Variable Pressure Cutch: The Variable Pressure Clutch Kit reduces the spring tension for up to 50% reduction in clutch pull. The product will fit in stock primary and derby covers with no extra parts other than the VP kit supplies. At low RPM, where the clutch is more frequently engaged, the VP Kits make the clutch pull very light. As RPM goes up, the engine produces more torque and the VP clutch's centrifugal pressure applies more force to the clutch plate, eliminating slippage. Various kits are offered for the Evolution and Twin Cam enginess ranging from 80, 88, 95, 103 and 124 cubic inches for stock, Screaming Eagle and Stroker big twin models.
