FAQ

Yes. The 1947-O is designed to work with the OEM NV5600 HO flywheel (no flywheel included).

Approximately 400 HP and 800 ft-lbs in typical NV5600 HO applications, with smooth, tow-friendly engagement.

If your flywheel is worn or you want increased heat capacity from Organic/Feramic facings with a matched flywheel, step up to 1947-OFEK.

No. This part targets NV5600 HO years (2000.5–2005.5) with a 1-3/8" input. See our other South Bend kits for NV4500 or non-HO coverage.

Pedal effort is slightly higher due to the increased clamp load, but remains very streetable for daily/tow use.
