Tour Driver

The 2026 Titleist GTS4 is a tour driver built for players who want control over raw distance. At 440cc, it's noticeably smaller than a standard 460cc head, and that difference isn't cosmetic. Smaller heads spin less, shape shots more easily, and give confident ball-strikers the feedback they want at impact. Titleist didn't make this for everyone.

That compact profile pairs with an adjustable hosel, so you can dial in loft and face angle to match your exact swing tendencies. The adjustability matters more here than on a forgiving distance driver because the GTS4 amplifies your ball flight. Get the settings right and it's surgical. Leave them wrong and the miss shapes will tell you immediately.

Among Titleist's 2026 driver lineup, the GTS4 sits at the top of the tour hierarchy. It's not trying to save you from a bad swing. The design assumes you have one worth working with.

• Single-digit handicaps and scratch players who shape shots intentionally and want a driver that responds to what they do rather than quietly correcting it.
• Experienced players who find standard 460cc heads hard to aim at address and prefer the compact, workable look the GTS4 presents at setup.
• Anyone who fights a consistent miss off the tee and wants to use the adjustable hosel to set a permanent draw or fade bias into the head rather than compensating with their swing every round.

Frequently Asked Questions

How does the Titleist GTS4 compare to the GTS3?

The GTS4 is the more demanding option. It runs a 440cc head versus the GTS3's larger footprint, so you get lower spin and more workability but noticeably less forgiveness on off-center strikes. If you're debating between the two, the GTS3 is the easier driver to play. The GTS4 is specifically for players who want that compact head and are willing to trade protection on mishits for shot-shaping ability.

Is the 440cc head hard to get used to?

It depends on your background. If you've been gaming a 460cc driver for years, the GTS4 will look and feel smaller at address, and the margin for mishits is tighter. Players who have used tour-category equipment before or who play blades in their irons tend to adapt quickly. Others may need a few range sessions before the smaller profile stops feeling like a liability.

What loft should I get in the GTS4?

Most players using a 440cc tour driver run between 9 and 10.5 degrees. Since the GTS4 has an adjustable hosel, you have room to experiment after purchase, so starting in the middle of that range makes sense. Swing speeds above 105 mph usually want 9 to 9.5 degrees; anything below that tends to benefit from 10 degrees or more to get enough launch without sacrificing carry.

Can a higher handicapper use the Titleist GTS4?

Nothing physically stops you, but it wouldn't serve most higher handicappers well. A larger head has more moment of inertia, which limits the distance lost on off-center hits. The GTS4's 440cc head doesn't offer that protection. Mishits with this driver lose more distance and stray further offline than they would with the GTS3 or GTS2. Unless you're regularly breaking 80, one of those models is a better fit.

How does the adjustable hosel on the GTS4 work?

The hosel sleeve rotates into several labeled positions, each changing the effective loft and face angle of the driver. You use the torque wrench that ships with the club to loosen the screw, rotate to your desired setting, and re-tighten. Moving the face to a closed position encourages a draw; open encourages a fade. Loft changes affect launch angle and spin. A launch monitor is worth using when you first dial it in so you know exactly what each setting is doing to your numbers.
