Designed for 2001–2016 GM 6.6L Duramax engines, this complete kit replaces all 32 valves with premium components that are built to handle the heat. Whether you're spinning high RPMs or hauling heavy loads, the tapered springs provide the higher spring rate needed to eliminate valve float and improve throttle response. These aren’t just upgrades, they’re essential if you want reliability under stress. Made from high-strength chromoly, every spring seat, retainer, and keeper is built to hold up to performance abuse while keeping your valvetrain tight and responsive. This is the same hardware PPE installs in their cast iron cylinder heads, so you know it's battle-tested. If you're ready to get serious about your engine build, this kit is a no-brainer. Engineered To Eliminate Float And Boost Response The PPE 110090050 kit includes 32 valve springs, retainers, spring seats, and keepers specifically designed for 2001–2016 Duramax-equipped GM trucks. Each component is crafted from chromoly steel, a material chosen for its excellent strength-to-weight ratio and high resistance to fatigue. The valve springs feature a tapered profile and higher spring rate, helping to maintain precise valve control and eliminate float during high-RPM operation. By reducing valvetrain weight and increasing spring stiffness, the kit enhances engine responsiveness under demanding conditions. It’s an ideal match for performance builds, especially when tuning or turbo upgrades push the limits of factory hardware. This complete kit ensures compatibility across all 32 valves, providing even pressure distribution and consistent timing. Whether you're installing fresh heads or upgrading worn components, PPE's valve spring kit is designed for durability and built to perform. Backed by a 1-year limited warranty, it brings both confidence and capability to any Duramax engine project.
