Dr.Pulley high performance clutch HiT 161310 Get quicker, harder
launches & positive engagement with these HiT Clutches. Everything you
could want out of a performance clutch, from fantastic machining and
craftsmanship to great feel and response.

The Dr. Pulley clutch and bell set is designed to be tuned to your vehicle and comes with at least six sets of springs - three clutch arm spring sets, and three pillow spring sets.

The HiT clutch has a secondary mechanism that engages when your CVT system reaches a certain RPM (tunable with the included three sets of "pillow" springs). This secondary mechanism locks the clutch arms in place against the clutch bell preventing clutch slippage when under load.

Dr. Pulley makes some of the best performing variators, clutches, and roller weights in the world. This HIT Clutch will maximize your your stock scooter or racing scooter's performance. The HIT clutch utilizes the push pin technology to create a more responsive clutching action, higher throttle response, and a more powerful mid range for hills and racing.
