FAQ
Will this clutch handle heavy towing?Yes. The organic 13" disc with a 3" wide lining is designed for smooth, controlled engagement under heavy loads—ideal for work and tow rigs.
What power level is it actually rated for?
Typical guidance is up to ~425 HP and around ~900 ft-lbs on properly maintained trucks. If you plan to exceed that, consider a dual-disc.
Does it include a flywheel?
Yes. The kit includes a matched flywheel to ensure correct stack height and release geometry.
Is this for NV5600 HO only?
Yes—this 1947-OKHD kit targets the HO NV5600 (2000.5–2005.5) with the 1-3/8" input. Earlier non-HO or 1.25" input applications require different part numbers.
How’s the pedal feel?
Noticeably firmer than stock but remains street-friendly with predictable, smooth engagement.
