NV5600 245HP H.O. TRANSMISSION OWNERS NOTE--- If you have a NV5600 6-Speed HO manual transmission (2000½-2005½ 245HP 5.9L Cummins), then you can order just a clutch kit rather than a clutch & flywheel kit. The South Bend clutch kit will fit the factory flywheel. Please specify which flywheel is in your truck to get the proper pilot bearing.
NV4500/NV5600 (NON-H.O.) TRANSMISSION OWNERS NOTE--- If you have an NV4500 5-speed (1994-2004) or NV5600 6-speed NON H.O. (1999-2000), then you MUST already have a South Bend flywheel in your vehicle. The South Bend clutch kit is NOT COMPATIBLE with the factory flywheel.
