NV5600 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.
G56 TRANSMISSION OWNERS NOTE--- If you have a G56 6-Speed manual transmission (2005-2015 5.9/6.7L Cummins), then you MUST already have a South Bend flywheel in your vehicle. The South Bend clutch kit is NOT COMPATIBLE with the factory flywheel.
