Project X Graphite Technology

Zonal Design Theory
Project X driver and hybrid shafts are engineered using True Temper’s proprietary Zonal Design Theory (ZDT) which divides the shaft into three zones—butt, mid and tip sections. Each zone is optimized for performance using a specific design technology.

Butt section:

Hex-Axial Reinforcement Technology provides unmatched cross sectional stability minimizing energy lost to ovalization.

Mid section:

Constant Taper Design eliminates localized bending and creates even loading and unloading for maximum energy transfer.

Tip section:

Elongated Double Wrapped 55 MSI Reinforcement for a firmer tip section which minimizes droop and lag and reduces back spin.

Tour Launch and Spin
Like the Project X iron shafts, Project X driver and hybrid shafts provide penetrating launch conditions with ultra low spin. The stiff butt, soft mid-section combine with the double reinforced tip section to maintain a strong angle of attack and greatly reduce spin, even in higher loft drivers.
