Six-speed manual only. 2003-2006 VQ35DE, including RevUp, uses the external-release family; 2007-2008 VQ35HR uses an internal CSC family. Buy a complete matched disc, cover, flywheel, release-bearing/CSC solution, pilot part, bolts, and hardware plan. Excludes automatic, G35, 2009 Roadster, and twin-disc/race-only selection advice.
Aftermarket options
Stock-style dual-mass flywheel paths and matched single-mass packages have different noise, inertia, and release requirements. Do not combine a random disc/cover with an unverified flywheel or omit the HR CSC decision.
Before you buy
Six-speed only. VQ35DE/RevUp and VQ35HR packages are not interchangeable. A single-mass conversion can add gear rattle/chatter. Verify engine, production date, transmission, clutch/flywheel stack, release system, included bolts, and break-in instructions.
