FAQ
How much power will this clutch hold?It’s rated around 600 HP and 1,100 ft-lbs in NV4500 5-speed applications when used as intended (performance street/track). Slipping or exceeding ratings will reduce life.
Does this kit include a flywheel?Yes—this upgrade includes a dual-drilled 5-speed flywheel along with bearings, hardware, and alignment tool for a complete install.
Is this good for towing?Not ideal. The aggressive ceramic facings are designed for holding power, not smooth tow engagement. For tow-friendlier manners, consider the organic upgrade NMU70279-5SCE or Kevlar/Ceramic NMU70279-06-5SCE.
Break-in procedure?Typical break-in is ~500 miles of easy stop-and-go driving with no wide-open throttle or hard launches to seat the facings and maximize service life.
What else should I replace while I’m in there?We recommend fresh hydraulics and checking the actuation hardware: 94–97 HYD, 98–02 HYD, pivot, fork, spring.
