The Valair Heavy Duty Upgrade Clutch NMU70G56-01 for your 2005.5-2018 Dodge 5.9L/6.7L Cummins is better than the OEM clutch you get from your dealer. This is due to the better quality materials used, the quality of the manufacturing process, and QC. Some companies also offer higher plate loads as options to the standard plate thus giving the clutch better holding ability than its OE counterpart. Best suited to trucks without or only minor power modifications. Good for light towing at stock HP levels. For use on 2005.5 & up G56 6-Speed Transmissions.
