2021 Titleist TSi2 and TSi3 drivers continue the Titleist Speed Project

The new 2021 Titleist TSi2 and TSi3 drivers are all about getting more distance more often, and the engineering team behind the TSi Series have exhausted every possible avenue to build the fastest, longest, and most consistent drivers they have ever put into the hands of golfers.

But, before we get to what’s new, we have to take a look back. The Titleist TSi Series drivers build on the unprecedented success of the original TS Series, which were kicked off with the introduction of the TS2 and TS3—the first drivers to come from what Titleist calls its “Titleist Speed” Project (in case you were curious what TS stands for). This resulted in Titleist forever changing the way they design and build their drivers, with the TS Series having 20-percent thinner crowns and faces six grams lighter than the previous models.

These changes and engineering breakthroughs immediately thrust Titleist into the conversation around the fastest drivers on the market, and forever did away with the old “they’re really good but not the longest” stereotype.

This “new boundary-pushing Titleist” is no accident either. Since 2008, the golf club R&D department has gone from 13 engineers and designers to over 70—that means more brainpower focused on each individual project, which in turn results in more people time per product category and better golf clubs.

Titleist’s driver evolution – From “concept” to reality

As much as the conversation around the new TSi2 and TSi3 drivers is about the evolution from the original TS Series, the truth is it really started years before that with the C16 (“C” standing for Concept and 16, its year of release, 2016 ). It was the first time Titleist introduced to consumers what it called a “no holds barred approach to design and materials”—a true “if we build it, they will come” line of clubs. The C16 driver alone debuted with a $1,000 price tag…and quickly sold out.

For Titleist and its team of engineers, it allowed them to remove the reigns of cost and do whatever it takes to push manufacturing and material technologies in search of ultimate performance. Looking back on the C16 driver now, even then they were dropping hints about future designs.

“These clubs are previews of what’s to come. Maybe not in the next generation. Maybe in two generations.” – Titleist on the C16 series.

The C16 driver gave us SureFit adjustable CG (center of gravity) weighting, which became part of the full retail line in within a year with the launch of the 917D3—and here’s the big one: an ultra-thin, ATI-425 Titanium Crown, the first driver to use this super-strong patented material in the golf club space.

Titleist TSi2 and TSi3 drivers

The “i” is for “innovation”

Titleist’s ATI-425 Titanium face

Titleist has enjoyed using extra letters to denote key features of some of its newest models—the most recent is the T100s with the “S” standing for both “strong” and “speed.” The “i” in TSi is no different but it has a few more meanings attached beyond the obvious “innovation.”

Inertia

Both of the new TSi Series drivers have boosted MOI over the previous generation beyond the traditional heel and toe forgiveness.

Engineers spent a huge amount of time figuring out a way to make the drivers more stable higher and lower on the face to help boost “high-low” MOI to create smaller launch windows and greater spin robustness. Spin robustness is a term we will continue to hear more about since driver faces can’t get any faster (off the middle), per the rules of golf, but enhancing a club’s ability to generate tighter spin robustness creates more consistent numbers and smaller standard deviation from optimal conditions.

The now 2 generations old 917 Series with ARC on sole

This was achieved in previous generations of Titleist drivers with ARC (Active Recoil Channel), to aid shots hit lower on the face, but it required the use of extra material which was able to be eliminated with the launch of the TS. In essence, Titleist engineered it obsolete for use in their drivers.

According to Titleist, the TSi2 has an improved high/low inertia of 13 percent, while the TSi3 comes in at 10 percent. In the world of engineering, single percent advancements are considered a big step so for Titleist to hit double digits on both products should be considered a big leap.

The final part of the inertial story is about shaping—for both speed and altering the internal weight properties of both drivers to make them more forgiving. Shaping is less a technology component and more about the overall design because when it comes to manufacturing a driver head, adjusting the shape doesn’t add cost—engineers call this “free technology.”

The weight saving and reshaping resulted in lower, deeper centers of gravity for both heads, which when taken out into the real world for testing creates more dynamic loft—this is why for the TSi Series drivers the lofts have all been strengthened by 1/2 degree to help maintain proper launch windows.

The reshaping also created a 15-percent reduction in total drag around the head thanks to improved aerodynamics. Truly no detail has been overlooked.

Impact

The Tsi2 and TSi3 drivers utilize ATI-425 titanium for the face insert, allowing engineers to once again make the faces thinner to reduce weight while also increasing the overall elasticity for better ball speed retainment. ATI is also known as Allegheny Technologies Incorporated, and you will find their logo has a nice little place on the face of the new drivers.

To add some additional background, ATI is a massive specialty materials company headquartered in Pittsburgh, PA, with sales that surpassed $4 billion dollars in 2019. Materials they have designed are used in medical devices, jet engines, nuclear submarines, wind turbines, deepsea mining, military aircraft bodies, and other defense applications.

The ATI-425 titanium is manufactured in their state of the art factory in Pittsburgh, and compared to the conventional titanium alloys used in golf, offers a six-percent higher yield strength, four-percent higher tensile strength, and most importantly a 30-percent higher ductility. Titleist is currently the only company using ATI-425.

This titanium material allows Titleist engineers to design thinner, faster faces since it can handle higher stress while remaining extremely durable. This leads to higher COR/CT around the entire face while still keeping within compliance of the rules. It’s a fine line to walk, but when you’re pushing limits of performance, you need to look for every advantage.

The other advantage Titleist has on the manufacturing side is engineers don’t cut corners. Every head is tested for CT multiple times in multiple locations through the process—this leads to some of the tightest tolerances in the industry and ensures that the driver in your hands is at the limit. It’s no different than how Titleist treats clubs on the other end of the spectrum by measuring the grooves of every single Vokey wedge that comes out of production.

The final part of “impact” is of course the moment of impact and acoustics. The new Titleist TSi drivers have already been described as being “solid soft” (which I realize is an oxymoron). They have a nice pitch that lets you know you hit it well, but the overall tone is softer and more elongated rather than sharp. It’s not an easy thing to achieve when you have a thin-wall constructed object hitting another solid object traveling over 100 mph, but to get a good idea, here is our own Johnny Wunder hitting a TSi3.

Integration

This is where we bring together the new materials and the redesigned aerodynamic shape and add in a few more pieces of new and improved technology.

SureFit weighting goes all the way back to the C16, which was the first Titleist driver to offer an adjustable center of gravity. Since then, Titleist has continued to refine the technology, and the TSi3 represents by far the best system to date for both golfers and fitters alike for a number of reasons.

First, let’s talk about fitters. The original SureFit was the perfect “set it and forget it” system, but it also meant that if you had to check how the driver was set up, you had to look very closely at the small port. Then you had to pull the cap off, get out your weight kit, adjust, and then finally reinstall the cap. I’m willing to bet Titleist had to ship out a few replacement caps to golfers that lost them during the adjusting process.

The new system eliminates the need to remove any cap and instead replaces the old port with a new set five-position track. The driver comes stock with an eight-gram weight with additional weights available in two-gram increments up to 12 grams and down to four. This makes dialing in head weight and ball flight tendencies much easier than before and improves the overall fitting process.

Now for golfers. Beyond the much great ease of adjustability, the biggest issue some found with the configuration of the TS3’s sole was the way the SureFit port stuck out from the sole and created some resistance in the backswing—it was a comment both from regular golfers and some of Titleist’s tour staff. It seems like a minor issue, but when you’re about to launch a golf ball 300 yards down a fairway, it’s pretty important to feel comfortable making a backswing.

And there we have it, new face, new sound, new shape, and new weighting system to make the TSi Series drivers the best Titleist drivers to date—but wait there’s more!

New featured & premium featured shafts

With Titleist’s position as a premium golf brand, it is officially eliminating the word “stock” from its vocabulary and replacing it with “featured.”

At Titleist, we are a premium brand and the TSi series woods are a premium performance product. For that reason, we only use real deal aftermarket shafts – not make for “stock shafts.”

Yes, it’s just a name change, but it demonstrates just how far Titleist is willing to go to differentiate itself from its competition—even when it comes to its off the rack featured shaft offerings which include

Project X HZRDUS Smoke Black RDX: Weight- 60 & 70 grams. Launch- Low/Mid. Spin- Low/Mid, Flex- 6.0 & 6.5
Mitsubishi Chemical Tensei AV Blue RAW: Weight- 55 & 65 grams. Launch- Mid. Spin- Mid. Flex- R, S, and X
Mitsubishi Chemical KURO KAGE Black DC, 5th gen: Weight- 50 & 55 grams. Launch- High. Spin- Mid. Flex: A, R, and S

Beyond the featured shafts, Titleist is also offering what it is calling premium featured shafts in partnership with Graphite Design. This allows golfer access to Graphite Design’s top-three shaft brands for a reduced price compared to previous generation drivers.

TOUR AD – DI: Weight- DI 5,6,7,8. Launch- Mid/High. Spin: Low | Flex: X, S
TOUR AD – XC: Weight- XC 5,6,7,8. Launch- Low/Mid. Spin: Low | Flex: X, S
TOUR AD – IZ: Weight- IZ 5,6,7,8. Launch- Low/Mid. Spin: Low | Flex: X, S

All Graphite Design shafts are manufactured in Japan to the highest quality standards, and offer unmatched stability and feel by using aerospace quality carbon fibers and cutting edge technology.

But what about a TSi4…and a TSi1?

This is the million-dollar question, and unlike with the previous generation, Titleist has been a little more open about discussing future line add-ons.

The TSi4 has already been spotted on the USGA conforming list, and in the bag of at least one PGA Tour player, while the TSi1 has not yet been spotted. The likely reason is the TSi1 will be a club designed to cater to golfers at the lower end of the speed spectrum much like the TS1, and since there aren’t any tour players swinging under 90 mph with their driver, there isn’t any rush to get it on the USGA conforming list until closer to its official release date—rumor has sometime in the spring of 2021.

But since both of these clubs are designed for the smallest portion of the fitting bell curve, the chance is if you are in the vast majority of golfers looking to get fit into a new TSi series driver, the TSi2 and the TSi3 is going to offer you an ideal platform to optimize performance and consistency.

Why Rickie Fowler is switching to a shorter driver at the PGA Championship

Published

May 13, 2026

Alistair Cameron

In a golf world where players are looking to eke out every yard possible, usually by lengthening their drivers to add clubhead speed, there’s one player at the PGA Championship who’s going in the opposite direction. In fact, for Rickie Fowler, his goal off the tee is not about gaining extra distance or yards north to south, but rather about shrinking the misses from east to west.

Ahead of the PGA Championship and the week prior at the Truist Championship. Fowler mentioned to Cobra Tour Rep Ben Schomin that the driver didn’t quite swing feel the same as everything in the bag. As a result, and with Schomin’s suggestion to try and sync everything up with the big stick, Fowler decided to test out a shorter length shaft.

“He’s been at 45 (inches), and he’d been at 45 for a few weeks, 44 1/8 (inches) is really is where he is been living really for the most part, for the last couple of years, and is where he is been comfortable,” Schomin told GolfWRX. “It just felt like it was a little long and loose on him.”

Interestingly, Fowler ranks 40th in Driving Accuracy this year on the PGA Tour. It’s his most accurate season with the driver since the start of the decade. But sometimes for players, feel is more important than statistics.

“It was really more of a trying to get the swing to feel the fluidness from club to club to club to try to get it to feel the same,” Schomin added. “And so we took it down to 43 and a quarter, and it was a touch of a ball speed loss, just based on that overall club head speed. But honestly, he squared it up probably a little better. The right miss wasn’t nearly as far. So really, overall down-range dispersion tightened up a fair amount, and he felt confident in swinging it.”

The change in length had Fowler’s caddie, Ricky Romano, beaming at how well he had driven during Tuesday’s practice round at Aronimink. So much so, he was asking Schomin not to suggest changes anymore.

Fowler’s shaft-shortening is one of a few driver adjustments he’s made this season, and to Schomin’s credit, it’s thanks to the fact that he and the rest of the Cobra team had Fowler fit very well into three of the four heads in the Cobra OPTM lineup.

“He had three distinct drivers and the biggest decision was trying to decide which worked best at that time,” Schomin told GolfWRX previously. “He’s played the majority of the season with OPTM X, but has also played a couple of tournaments with OPTM LS. His overall driving stats have been good.”

At the RBC Heritage earlier this spring, Fowler switched drivers, changing from his Cobra OPTM X and into the Tour, low-loft Max K model that Gary Woodland used to win just a few weeks prior.

Now for the PGA Championship, Fowler’s back in the X head, but still using the UST Mamiya LIN-Q PowerCore White 6TX shaft, just a little bit shorter.

“Will he stay there? I’m not sure,” Schomin added. “Could we end up say at like 43 and 7.5 (of an inch). If it’s giving him the same feel of consistency through the bag, then I think we might end up just a touch longer. But if he likes where he is at, he’s confident where he is at, that’s really all that matters.”

If there’s more testing, though, just don’t tell his caddie.

GolfWRX Launch Report: 2026 Titleist GTS drivers

Published

May 13, 2026

GolfWRX Staff

What you need to know: As is customary for the Fairhaven-based company, Titleist officially announced today that its GTS drivers are headed to retail, following a successful tour release. The GTS2, GTS3, and GTS4 drivers will be available in golf shops June 11.

Since debuting at the Texas Children’s Houston Open, the new GTS lineup has quickly gained traction on the PGA Tour, with more than 50 players already making the switch to a GTS2, GTS3, or GTS4 driver. Among them are Justin Thomas and Jordan Spieth.

According to Titleist, the GTS series builds upon the performance foundation established by the GT Series, while introducing several major technological advancements, including a new Split Mass Frame construction, refined aerodynamics, and an updated Speed Sync face design.

2026 Titleist GTS drivers: What’s new, key technology

Split Mass Frame and thermoform body

At the center of the new GTS lineup is a redesigned internal structure: the Split Mass Frame. This technology works with a full-thermoform body made from Titleist’s Proprietary Matrix Polymer (PMP), a lightweight composite that enables engineers to reposition mass more efficiently throughout the head. Compared to the previous GT generation, GTS drivers feature nearly double the PMP material, increasing from 13 grams to 26 grams, while maintaining the sound and feel preferred by better players.

The weight savings from the thermoform construction allowed Titleist engineers to strategically separate mass placement inside the head. Specifically, more weight is pushed rearward to improve stability and forgiveness, while additional mass is positioned low and forward to optimize speed, launch, and spin.

In short, golfers are able to maintain ball speed and consistency across both centered and off-center strikes.

Faster aerodynamics

Titleist also refined the aerodynamic shaping of the GTS heads to help players generate more clubhead speed.

The tails of the new GTS2 and GTS3 heads have been raised compared to previous models, helping airflow stay attached to the crown and sole longer during the swing. According to Titleist, the improved airflow reduces drag and increases speed without affecting launch conditions or center of gravity placement.

Typically, aerodynamic gains can compromise forgiveness or launch characteristics, but the weight savings from the Split Mass Frame allowed engineers to preserve preferred CG locations.

New Speed Sync face

The new Speed Sync Face design is engineered to improve ball speed retention across a larger portion of the face. A reinforced perimeter structure helps maximize face deflection and COR on centered strikes, while the upper portion of the support ring is opened up to increase speed on high-face impacts, a common strike location for many golfers. The face also features a variable thickness design to preserve speed and performance across a wider impact area.

Expanded adjustability

Each GTS model includes a dual-weighting system to fine-tune launch, spin, and shot shape more precisely than previous generations. GTS2 uses interchangeable forward and aft weights, while GTS3 and GTS4 combine a rear weight with an adjustable forward track weight system.

Tour-inspired face graphics

The new lineup features redesigned high-contrast face graphics to improve alignment and framing at address, according to Titleist. Sharp visual lines are designed to make it easier to center the golf ball and to perceive loft more easily at setup.

Additional model details

GTS2

The GTS2 is the most forgiving model, designed for golfers seeking maximum stability and consistent speed across the face.
It produces high launch with mid spin and features a larger, confidence-inspiring profile behind the ball.
Standard weighting includes an 11-gram forward weight and a 5-gram rear weight, with additional fitting configurations available.

GTS3

The GTS3 is aimed at players who want more control over launch, spin, and shot shaping.
Compared to GTS2, the GTS3 offers lower launch and spin while featuring a more compact profile and deeper face design preferred by many stronger players.
The head features an adjustable forward-track weight system to further fine-tune center of gravity placement.

GTS4

The lowest-spinning option in the lineup, GTS4 is built for golfers looking to reduce excessive spin and maximize total distance.
Unlike previous “4” models from Titleist, the new GTS4 features a full 460cc profile that improves forgiveness and stability while retaining its low-spin DNA.
Like GTS3, it includes a forward track weighting system for precise fitting adjustments.

What Titleist says

“When we talk about driver design, it’s never about the one feature or benefit — it’s about all of them,” said Stephanie Luttrell, Titleist’s Senior Director of Metalwood R&D. “Ball speed, forgiveness, spin stability, adjustability, exceptional sound and feel… these are all attributes that golfers care about. It’s our job to design a lineup that elevates performance across the board without sacrificing in key areas, and we feel we’ve done that with GTS.”

“We know that forward CGs drive speed with great launch and spin characteristics, but you need to be able to do that with an inertial stability that still preserves ball speed, launch and spin consistency on off-center hits,” Luttrell said. “We’ve never before been able to hit these CG positions and inertia properties at the same time, and we’re achieving that because of GTS’ construction.”

Club Junkie’s take

I feel like every time there is a new Titleist wood release, I figure they can’t outdo their previous driver. And every year, I am wrong and impressed with the performance. The GTS fits right into that narrative again, as I didn’t know where Titleist could go from GT, but they pushed the limits again, and my fitting proved the smart people there found ways to improve.

My past four Titleist drivers have been a 2 series as my swing typically requires a little height, spin, and forgiveness so I figured I would just get a new GTS2 and be on my way. During the fitting, I was impressed by the new GTS construction, its added PMP material, and the advanced adjustability on each model. My fitter, Joey, got to work putting together a GTS2 and we started there. The launch and spin were great, and the consistency on misses was very tight. My average ball speed with the GTS went up a little bit as the new Speed Sync face creates more speed away from the center.

Joey then built up a GTS3 in 11 degrees, but I figured this wouldn’t have the stability I needed for tight dispersion on my miss hits. That thought was quickly erased after a few shots, and I really liked the more center start line and reduced draw on the misses I was seeing. We tried a few different settings and shafts to dial in the details in order to get the best fit. Having a forward and rear weight in the head allowed Joey to set up the GTS3 with a heavier rear weight to keep the launch and spin up, while the Sure Fit hosel set flat created a more center start line for me. My misses were not nearly as far left, and I was really impressed with the consistency on the spin and launch when I didn’t hit it in the center.

Titleist again created a wood line in GTS that delivers improvements over previous drivers while keeping the traditional look and feel you expect. More adjustability, better off-center speed, and 3 drivers that are playable over a wider range of players should make these extremely successful in fittings.

Titleist launches new GTS2 and GTS3 fairways

Published

1 day ago

May 13, 2026

Gianni Magliocco

Titleist has today introduced its new GTS2 and GTS3 fairways.

Lower and deeper center of gravity (CG) positions, new adjustable heel-toe weights and advanced clubface innovations drive total performance in the two tour-proven models.

New GTS fairway technology:

Wraparound composite crowns: Unlock lower CG positions for higher launch and lower spin as well as more CG depth for added forgiveness.

Refined shapes and profiles: With two distinct setups, with GTS2 featuring a shallower face height and larger address profile compared to GTS3’s deeper face and more compact profile. Both models feature flatter sole designs for better performance off the turf.

Dual-weighting systems: The dual-weighting systems allows for personalized performance, with interchangeable heel-toe flat weights helping to fine-tune CG location across the face.

A forged L-Cup face design: The new face design is optimized for GTS and works to preserve ball speed, maintain launch conditions and enhance sound and feel on low-face impacts.

Tour-inspired polished clubfaces: To help players see more of the clubface at address.

GTS2 Fairway

The new GTS2 fairway is designed with a shallower face and a larger profile than GTS3, ideal for players with more sweeping deliveries with their fairway metals.

GTS2’s new face height, inspired by tour feedback, was designed shallower than the prior generation GT2 model and more in line with the GT1 fairway. Each loft in GTS2 leverages a shallower profile except for the 13.5-degree, which maintains a slightly taller face.

With its new dual-weighting system, the ‘2’ model now has heel-toe CG adjustability.

Lofts: 13.5, 15.0, 16.5, 18.0, 21.0

Dual-weight system: 11-gram weight in heel, 5-gram weight in toe (standard)

GTS3 Fairway

The new GTS3 fairway is designed with a deeper face and a more compact profile, ideal for players who hit down on the golf ball more with their fairway metals.

New to the GTS3 family is a 21-degree offering, giving players two distinct profiles in Titleist’s 7-wood loft.

Instead of the track weight system featured in prior generation ‘3’ models, GTS3 now benefits from adjustable heel-toe flat weights.

Lofts: 15.0, 16.5, 18.0, 21.0

Dual-weight system: 11-gram weight in heel, 5-gram weight in toe (standard)

Price & Availability

The new GTS fairways are available for fittings and pre-sale now and will be in golf shops worldwide beginning June 11 priced at $399 (standard) and $599 (premium).
