XDP XD313 Performance Valve Springs & Retainer Kit

Control the valvetrain in your 1998.5-2018 Dodge 5.9L & 6.7L Cummins with the XDP 24V Performance Valve Springs & Retainer Kit XD313. Valve springs are an essential upgrade that are often overlooked in many performance builds. The factory valve springs in your engine are not intended to handle the increased engine RPM and elevated boost levels that are typical in modified applications. Even common upgrades like an aftermarket turbocharger and performance tuning can cause valve float that may result in serious engine damage. 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. This is why upgraded valve springs are a must-have on modified engines!
