FAQ
How much power will this clutch hold?It’s rated around 600 HP and 1,100 ft-lbs thanks to the ceramic facings and 3400# pressure plate.
Is this okay to tow with?No. This ceramic “performance replacement” is not for towing. For tow-friendly drivability, choose the organic or Kevlar/ceramic options listed above.
Does it include a flywheel?No. This kit includes the disc, pressure plate, bearings, and alignment tool. If your flywheel needs replaced, use the matching NV5600 unit: V3434.
Which hydraulic kit should I use?Use NMU70HYD-02 for 1998–2002 trucks and NMU70HYD-03 for 2003–2005.
Daily driving manners?Ceramic buttons offer aggressive engagement ideal for racing/pulls and spirited street use. Expect more on/off behavior vs. organic. Break in per Valair’s guidance.
