Description
UST Mamiya TSPX DART V 120 X-Stiff Iron Shafts
The UST Mamiya TSPX DART V 120 X-Stiff Iron Shaft is engineered for elite ball strikers who require maximum stability and precision from their equipment. At 120 grams and built with an extra stiff profile, this Tour-level graphite shaft offers ultra-tight dispersion, reduced torque, and the kind of consistency that aggressive swingers can trust round after round.
Designed exclusively for certified TSPX dealers, the DART V 120 X-Stiff utilizes UST’s Dual Action Recoil Technology to create a seamless energy transfer throughout the shaft. This design minimizes flex inconsistencies and eliminates weak zones, giving better players total command over shot shape, launch height, and spin rate — especially under high load.
At its core is M40X — a high tensile modulus carbon fiber developed by TORAY Industries. M40X delivers a 30% strength improvement over standard carbon fiber and is paired with proprietary nanoalloy resin systems to suppress vibration and remove the harsh, boardy feel that often plagues stiff graphite builds. The result is a low-torque powerhouse that feels refined, launches true, and responds cleanly to elite swing mechanics.
Best fit for: Strong, high-speed players seeking a low-launch, low-spin Tour-weight iron shaft with X-Stiff responsiveness, superior dispersion control, and advanced composite feel.
