What makes the Dr Pulley HiT (High-Thrust) Clutch so special and worth the extra cost? 

The Dr Pulley HiT clutch has high-quality clutch pad material running the length of the clutch arms for maximum surface area engagement with the clutch bell.  The stock clutches often only have a small patch of soft clutch pad material in the center of the clutch arms.  Additionally, the HiT clutch has a secondary mechanism that engages when your engine reaches a certain RPM (tunable with the included multiple sets of "pillow" springs).  This secondary mechanism locks the clutch arms in place against the clutch bell minimzing clutch slippage when under load!  The result? Solid clutch engagement at all times, particularly when accelerating and climbing.  The Dr. Pulley HIT clutch is designed to be tuned to your vehicle and comes with at least six sets of springs for all your tuning needs. 

Performance Clutch Bell:

The included clutch bell is a high performance replacement for your smoothed-out stock clutch bell.  Solid engagement with the clutch bell is key to power when climbing! 

Dr Pulley Variator:

This racing variator from Dr Pulley is precision engineered to increase performance over stock variators.  The steep-angled ramp plates in the Dr Pulley variators allow for faster and smoother engagement at all speeds as well as allow lighter weighted sliders to fully extend to make the most of your CVT system.  Longer channels create a more aggressive acceleration profile compared to stock variators.

Note: for most vehicles we do not recommend installing the spacer washers that come with the Dr Pulley variator as it can result in a loss of top speed.
