FAQ
How much power will this clutch hold?It’s rated around 500 HP / 1,000 ft-lbs for street/tow use with the included 3400# pressure plate.
Is this truly a 13" conversion for my 5-speed?Yes. It replaces the factory 12.25" setup with a 13.00" disc and matching flywheel designed for the NV4500 5-speed.
Will I need a starter spacer?No when using the included 5-speed conversion flywheel. A spacer (V2151) is only required when using a 6-speed flywheel on an NV4500.
What should I replace while I’m in there?We recommend fresh hydraulics (94–97, 98–02) and linkage parts (pivot, fork, spring) for best feel and longevity.
