# Justin Thomas' WITB: the 2026 Titleist setup

> A new GTS2 driver, a putter switch and a set of one-off prototype blades. Every club in JT's full Titleist bag for 2026.

**Setup verified:** 2026-07-13

Justin Thomas is a full Titleist staffer, and the headline change for 2026 is a fresh Titleist GTS2 driver on a Mitsubishi Whiteboard 63X shaft, replacing his previous GT-series head. He plays a decade-old Titleist 915 FD as his 5-wood, one-off 621.JT prototype blades in the 6-9 irons, Vokey SM11 wedges and the Pro V1x ball.

The other 2026 storyline is at the other end of the bag — a switch to a Scotty Cameron Phantom mallet, moving him away from the blade-style Cameron he gamed for years.

## Quick facts
- **Tour:** PGA Tour
- **Clubs:** Titleist
- **Driver:** Titleist GTS2 (~9.5°)

## Notes

The big 2026 move is the driver: Thomas is now in a Titleist GTS2 head with a Mitsubishi Whiteboard 63X shaft, and he's paired it with a putter change to a Scotty Cameron Phantom 9.5 mallet after years with a blade. Two eras of his game, both updated in the same season.

The retentions tell you as much as the changes. He still carries a roughly decade-old 915 FD as his 5-wood, and his 6-9 irons remain the bespoke 621.JT prototypes. A couple of slots genuinely vary across reputable sources — the long-iron model and whether a GTS300 mini driver is a regular gamer — so we've described those rather than guess.
