Titleist TSi4 Driver

TSi drivers offer players four distinct ways to take advantage of our most advanced metals lineup ever. Find the one that fits you and experience what it’s like to step up to every tee ready to perform.

TSi1 delivers maximum launch and distance for moderate swing speeds. TSi2 provides maximum forgiveness across the face. TSi3 offers speed-tuned performance.  TSi4 aggressively reduces spin.

FEATURES & TECHNOLOGY

ATI 425 Aerospace Titanium Face

Faster in the air and faster at impact, all Titleist TSi drivers push the boundaries of speed through advanced engineering and material breakthroughs – including a new ATI 425 Aerospace Titanium face construction never before used in golf – that combine to produce the longest, straightest, best-looking, and best-sounding Titleist drivers ever.

Player-Tuned Aerodynamics & Sound

The improved shaping of the TSi4 allows the club head to move faster through the air and deliver more power at impact. The TSi4 has been aerodynamically engineered to reduce drag up to 6 percent (versus prior generation TS4 model), increasing club head speed for greater ball speed and distance.

Multi-Dimensional Stability

Players often equate “high MOI” with heel to toe forgiveness, but we employ a more holistic approach to MOI design. TSi optimizes sole to crown performance by producing higher inertia values versus the prior generation TS models and delivers more speed and a tighter launch and spin range up and down the face.

Ultra-Thin Titanium Crown

The thinnest cast titanium crown in the game allows weight to be redistributed low and forward for reduced spin.

Streamlined Shape

The aerodynamic design of TSi4 –featuring a 430cc classic, pear shape–reduces drag, allowing golfers to swing faster for increased club head speed and more distance.

CT Tested And Maximized

Every TSi4 driver is precision manufactured to the tightest tolerances and measured multiple times to ensure performance is at the maximum allowable limit.

Performance-Tuned Adjustability

Features Titleist’s patented SureFit hosel with 16 independent loft/lie settings, plus headweight adjustability (in two-gram increments, ranging from -4g to 4g) to create a more consistent and optimized ball flight through precision fitting.
