Shop with Blessed Performance for the XDP Performance Valve Springs & Retainer Set for your 1989-1998 Dodge 5.9L Cummins diesel. Featuring a conical design that offers improved valve control over a basic straight spring.

This makes these springs a perfect option for a "one-and-done" upgrade that lets you upgrade your engine to support more power in the future. Each spring is subjected to a stress relief process and is computer load mapped to give a superior-quality product with long-term resilience. Tested within 1 lb of seat pressure, this valve spring & retainer set comes complete with locks, retainers, and springs.
