FAQ
What power will this clutch realistically support?Our listing rates this kit around ~350 HP / 800 ft-lbs. It’s ideal for tuned/towing daily drivers that want organic engagement and longer life than stock. For 400–500+ HP builds, see the ceramic or kevlar/ceramic options above.
Does it include a flywheel?No. Add the Valair V3434 flywheel if your existing wheel is worn or you’re converting. See “Recommended Supporting Parts.”
Which hydraulics do I need?Most 2000.5–2002 NV5600 trucks use the NMU70HYD-02 set; many 2003–2005 trucks use the later NMU70HYD-03. Verify by model year/VIN.
Is this for the NV5600 or G56?NV5600 only. If you have a 2005–2018 G56, choose a G56-specific clutch from our Valair lineup.
