Control the valvetrain in your 1998.5-2022 Dodge 5.9L and 6.7L Cummins with the XDP 24V Performance Valve Springs and Retainer Kit XD313. Valve springs are an essential upgrade that are often overlooked in many performance builds.

In addition, your valves can be blown open by boost and drive pressure causing reversion. Reversion is when exhaust gasses flow backwards and enter the cylinder on the intake stroke, hurting your engine performance.
