Split Mass Frame & Thermoform Body
At the heart of the new lineup is the Split Mass Frame construction combined with a full Thermoform body made from Titleist’s proprietary matrix polymer material.
The design allows significant weight savings while maintaining the sound and feel preferred by better players. Compared to the previous generation, the amount of Thermoform material has doubled, increasing from 13g to 26g while accounting for around 60% of the body surface area at only 13% of the total mass.
That freed-up weight is redistributed low-forward and deep-back within the head to optimize launch conditions while also increasing stability and MOI.
Speed Sync Face
The new Speed Sync Face technology is designed to improve ball speed consistency across the face while maintaining stable spin performance.
A reinforced perimeter structure increases flex and COR efficiency, especially on center strikes, while the redesigned upper face area improves performance on high-face impacts. Variable face thickness technology further enhances speed retention across the hitting area.
Dual Weight System
Each GTS model also introduces a new Dual Weight System for expanded shot and launch customization.
The GTS2 features front and rear flat weights (standard setup: 11g front / 5g rear), while the GTS3 and GTS4 combine a forward track weight (8g) with a rear flat weight (5g).
By repositioning weight farther back, golfers can increase launch and spin characteristics, while custom fitting allows additional weight configurations beyond the standard setup.
Improved Aerodynamics
The GTS drivers feature refined aerodynamic shaping designed to reduce drag and improve clubhead speed.
The GTS2 and GTS3 both feature a raised tail section that improves airflow transition from crown to sole. While highly aerodynamic heads can sometimes compromise ideal CG positioning, Titleist says the Split Mass Frame allows both aerodynamic efficiency and optimized weighting to work together.
High Contrast Face Graphics
A new high-contrast face alignment design highlights the center of the face, helping golfers position the ball more precisely at address and improve visual confidence.
