XD390 XDP Heavy Duty High Boost Valve Spring Set - Dodge 5.9L/6.7L Cummins 1998.5-2024

Overview

Control the valvetrain in your truck with the XDP Valve Spring Set. Common upgrades like aftermarket tuning, fueling and turbo upgrades can cause valve float that can result in severe engine damage. The intake valve in your truck could also be blown open from added boost levels and exhaust drive pressure which allows reversion. Reversion is when exhaust gasses enter the cylinder on the intake stroke, another condition that can hurt your power potential. These springs come ready for install using your factory retainers and locks.
