FAQ
Is this clutch good for towing with mild tunes?Yes. The OFE friction balances heat tolerance and smooth engagement, making it a strong choice for street/tow trucks with mild to moderate tuning.
Does the kit replace my factory flywheel?
Yes. This kit includes a solid/single-mass flywheel and the hardware needed for the ZF-6 application.
What pedal feel should I expect?
Pedal effort is firmer than stock, but engagement is progressive and predictable for daily driving and towing.
Will it hold 475 HP on a heavy truck?
It is rated to approximately 475 HP / 1000 ft-lbs. Heavier trucks or frequent high-heat use may benefit from stepping up to a dual disc.
What if I have a 2000.5–2003.5 build?
This part number specifically targets 1999–2003.5 ZF-6 7.3L applications; verify transmission and build date before ordering.
