Quick Verdict
Buy GT4 if...
- · You specifically want the compact 440cc address profile
- · You swing 110+ mph and can exploit the absolute lowest spin
- · You are an elite ball striker who rarely misses center
- · Budget matters and $399–499 fits better than $699
Buy GTS4 if...
- · You swing 95–110 mph and generate too much spin
- · You want low spin without the compact head penalty
- · You need fitting flexibility to tune draw/fade bias
- · The GT4's forgiveness was ever a concern for you
Why Titleist made the GTS4 a 460cc head: The compact GT4 sold in small numbers because very few golfers could actually handle it. By moving to 460cc and using the 5-position weight track to achieve forward CG — rather than head size — Titleist can deliver the same low-spin philosophy to a much wider range of players. The '4' model no longer requires tour-level ball striking to be worth hitting.

Head-to-Head Breakdown
The Biggest Change: 440cc to 460cc
GT4 (2024)
The GT4 — like every Titleist '4' model before it — used a compact 440cc head. This was a deliberate design choice: the smaller, shallower head appealed to elite-level players who wanted the most workable, tour-style profile available with a Titleist headcover. It was a niche driver for a niche player. The compact shape limited its appeal but made it distinctive.
GTS4 (2026)
The GTS4 breaks from that history. It is now a full 460cc head — the same size as the GTS2 and GTS3. Titleist moved the CG forward rather than shrinking the head to produce low spin. The result is a driver that achieves the same low-spin profile as the GT4 in a body that is far more forgiving and confidence-inspiring at address. It is a fundamentally different product philosophy.
Spin and Launch
GT4 (2024)
The GT4's fixed forward CG and compact 440cc head produce the lowest spin and lowest launch of any Titleist driver in recent memory. For tour players with swing speeds above 110 mph and elite ball-striking consistency, this profile maximises carry distance on a penetrating, efficient flight. In the wrong hands — anyone below 105 mph or with an inconsistent attack angle — the GT4 actively hurts distance.
GTS4 (2026)
The GTS4 achieves low spin through its 5-position weight track positioned toward the front. The spin is low — lowest in the GTS lineup — but slightly higher than the GT4 at equivalent loft settings. The launch is low-mid rather than low. For a fast swinger who generates too much spin, the GTS4 hits the target without demanding the GT4's consistency requirements. It is a more forgiving path to the same spin profile.
Forgiveness
GT4 (2024)
The GT4's compact 440cc head produces noticeably lower MOI than a standard 460cc head. On off-center contact — heel, toe, or low-face — the GT4 punishes inconsistency. Distance loss on mishits is significant. This is the correct trade-off for a tour player who rarely misses the middle; for most recreational golfers, it is a liability.
GTS4 (2026)
The GTS4 is far more forgiving than the GT4. The full 460cc head and doubled PMP material maintain much better ball speed on off-center contact. With the weight moved rearward on the track, it can even approach GTS3 levels of forgiveness while still producing the lowest spin in the lineup. This is the key selling point: low spin without the punishment of a compact head.
Who It Is Really For
GT4 (2024)
The GT4 is — and always was — a specialist club for elite-level players. It requires a consistent, repeating swing, high swing speed (105+ mph), and the ability to produce a precise attack angle. Cameron Champ and other tour players who thrive on the lowest-spin, lowest-launch profile are the correct audience. For anyone outside that description, the GT4 is the wrong call.
GTS4 (2026)
The GTS4 dramatically widens the audience for the Titleist '4' concept. A golfer swinging 95–110 mph who generates excess spin can now get the low-spin profile without sacrificing forgiveness or needing tour-level ball-striking consistency. The 5-position track also allows the GTS4 to be partially de-tuned toward the GTS3's territory — versatility the GT4 never had.
Verdict
The GTS4 is the right call for almost every golfer who previously considered a '4' model Titleist driver. It delivers the same low-spin philosophy in a 460cc head with a 5-position weight track — meaning you get low spin without the punishment, and adjustability the GT4 never had.
The GT4 remains the right call for one specific type of player: the elite-level golfer above 110 mph who specifically wants the compact 440cc address profile and can handle the forgiveness trade-off. For that player, the GT4 at $399–499 is also exceptional value. For everyone else, the GTS4 is the superior product and represents a genuine step forward in what the '4' designation can offer.
Where to Buy
Frequently Asked Questions
Why did Titleist make the GTS4 a 460cc head?
To widen the audience for the '4' model's low-spin philosophy. The GT4 and all previous Titleist '4' models used compact 440cc heads that required elite ball-striking consistency. By using a 5-position weight track to achieve forward CG in a 460cc body, the GTS4 delivers comparable spin numbers with dramatically better forgiveness — accessible to any fast swinger with a spin problem, not just tour players.
Is the GTS4 harder to hit than the GT4?
No — the opposite. The GTS4's 460cc head is significantly more forgiving than the GT4's compact 440cc head. The GT4 was punishing on mishits; the GTS4 is not. The GTS4 is the more accessible driver by a meaningful margin.
What swing speed does the GTS4 target?
The GTS4 targets golfers with driver swing speeds of 95–110 mph who generate excess spin and want a lower, more penetrating flight without sacrificing forgiveness. The GT4 was suited to 110+ mph with elite consistency; the GTS4 opens that profile to a wider range of skilled players.
Should a GT4 player upgrade to the GTS4?
Only if you want a 460cc head. If you specifically play the GT4 for its compact address profile and are comfortable with the forgiveness trade-off, the GTS4 is a different driver in that respect. If you play the GT4 purely for its low spin and would have preferred more forgiveness, the GTS4 is the upgrade you've been waiting for.
