DMAX Diesel 6.6 Performance Valve Spring Set | 2001-2022 GM Duramax 6.6L

Whether this set is for a daily driver or a race truck, the DMAX Performance Valve Spring Set can handle it all. A simple upgrade like engine tuning can raise the engine RPM and boost pressures. The stock spring's design tends to oscillate at high RPMs, this can put a lot of stress on valvetrain components. When the stock springs get weak or pushed past their limits, they can stay open when they're not supposed to. This will result in performance loss and can cause damage as well. Conical valve springs naturally dampen and reduce oscillation without creating more heat and friction. The result is a longer valvetrain life expectancy and the ability to handle higher pressures, all while reducing weight compared to the standard spring design. This spring set is perfect for replacing worn springs for trucks with up to 2,000HP race engines and everything in between.
