The PPE C5 Clutch Upgrade Kit is engineered to take that load without flinching. This kit was built for the kind of real-world abuse that comes with high torque numbers and constant pressure. It shines in First Gear, Reverse, and Park by improving holding power right where you need it most. The stronger grip means less slippage, better throttle response off the line, and a more direct feel when you're towing a full load or hammering the throttle. Complete Kit with No Guesswork Everything you need comes in the box. The PPE kit includes eight high-strength clutches and eight precision-matched steels, making it a true drop-in solution for 2001 to 2010 GM 2500HD and 3500HD trucks running the 6.6L Duramax with an Allison 1000 Series transmission. It’s ideal for those who want to build their transmission with confidence, knowing the components are proven to perform under pressure. Whether you're upgrading as part of a full rebuild or just trying to future-proof your setup, this kit brings serious capability without the headache. Once it's in, you'll feel the difference every time you shift—especially when your foot’s on the floor and your trailer’s at max weight.
