2001-2016 Duramax Valve & Spring Kit (110090080)

Fits

The intake/exhaust valve, valve seal, spring, spring seat/retainer/keeper kit comes standard with each PPE Duramax Cast Iron Cylinder head. This kit is specially designed for the GM 6.6L Duramax and contains the components for both driver and passenger side cylinder heads. The valves are fully nitridated and reinforced for superior durability and reliability. The tapered valve springs’ higher spring rate and lighter valve train weight enable faster response during high RPMs and eliminate valve float. Premium chromoly material construction ensures the longevity and durability of valve seats, retainers, and keepers.
