Variable Pressure Clutch (vpc By Tak's Performance Parts List

AIM strongly recommend VP Performance Kits to upgrade '98 and later Harley-Davidson stock clutch for any performance engines, even a Screamin Eagle Stage 1 Kit (Exhaust pipe, Air cleaner, EFI tuner). Because as you know Harley-Davidson has reduced clutch lever effort from 2006 Big Twin model by reducing clutch spring pressure about 10%. Even though clutch performance is 10% less than before, the current engine size has been increase to 96ci. That means clutch performance may not be enough when you do any engine performance modifications.

VP Performance Kits are the best product to upgrade Harley-Davidson stock clutch and eliminate unnecessary heavy clutch pull (not like a regular heavy duty spring), but add up to 40% additional pressure to clutch as engine RPM increases (Centrifugal Force) to make very strong clutch clamping force. VP Performance Kit is including VP92T and Clutch spring.

Note: In the Chart, The clutch will not slip when there is your engine torque curve below the clutch pressure curve. These pressure and handling torque in the chart are calculated with stock primary and final gear ratio. These numbers will be change by primary and final gear ratio.

One of the less desirable byproducts of increased power is the need for a clutch spring upgrade, and the additional lever effort it requires. By adding the Variable Pressure Clutch (VPC) devise, clutch plate holding pressure is reduced at lower RPM’s, and increased as RPM rises, reducing the chance of clutch slippage as power builds. The VPC system reduces initial pressure and uses weights. And if that isn’t enough, put the squeeze on your clutch pack with the S&S Variable Pressure Plate. The weighted clutch fingers use centrifugal force to increase the pressure on the plates. The faster you spin your engine, the stronger your clutch engagement, all without increasing the clutch lever pull at idle. 380 lbs pressure, 25% stronger. AIM is the distributor for Tak's Performance Products (TPP), manufacturer of the Variable Pressure Clutch (VPC). The VPC is a replacement pressure plate actuator that uses centrifugal force to put pressure to the clutch plates to keep them from slipping. The faster the clutch spins, the greater the pressure on the clutch plates. And if that isn’t enough, put the squeeze on your clutch pack with the S&S Variable Pressure Plate. The weighted clutch fingers use centrifugal force to increase the pressure on the plates. The faster you spin your engine, the stronger your clutch engagement, all without increasing the clutch lever pull at idle. 380 lbs pressure, 25% stronger. The Variable Pressure Clutch (VPC) by Tak's Performance Parts uses a system that reduces spring pressure at idle, and as the centrifugal force increases in line with rising engine rpm it provides the clutch with the required pressure to match engine torque.

Note: VP Performance Kits and VP Charger Kits ---Requires removing the outer primary cover to change the diaphragm spring. Non-stock derby covers (including any special or '03 anniversary cover) and 3 holes derby covers may require a derby cover spacer. Clutch pull becomes heavier as RPM increases. Will fit models equipped with H-D hydraulic clutch.
