Put the Power Down with Confidence

When you're making serious power with your 1994–2003 5.9L Cummins, the last thing you want is your clutch slipping under load. That’s where the Valair NMU70279-04-5SCE 13-Inch Upgrade Clutch comes in. This clutch kit is built for diesel owners who aren’t messing around—whether you’re towing heavy, daily driving with a tune, or putting your foot down just because you can. Rated for up to 600 horsepower and 1100 ft-lbs of torque, it’s more than capable of handling the demands of a performance build without sacrificing everyday drivability.

Durability Where It Counts

Valair didn’t cut corners with the components either. The ceramic button disc is built for serious wear resistance, giving you consistent engagement even under heat and stress. The heavy-duty spring hub helps absorb shock and prevent chatter, while the 3400# pressure plate offers the clamping force you need for crisp, positive shifts. This kit includes everything for a full install—flywheel, pressure plate, clutch disc, pilot and release bearings, and even the alignment tool. If you’re looking to put power to the ground without worrying about fade or failure, this clutch is a dependable, track-tested option that’s right at home in the real world.
