Fortify the valvetrain in your 1989-1998 Dodge 5.9L Cummins with the XDP Performance Valve Springs and Retainer Kit XD389. Valve springs are a vital upgrade often overlooked in performance builds. The stock valve springs in your Cummins engine are not designed to handle the increased engine RPM or higher boost levels common in modified applications. Even typical upgrades like an exhaust brake, aftermarket turbocharger, fuel plate, and injectors can trigger valve float, potentially leading to catastrophic engine damage.
Moreover, boost and drive pressure can push your valves open, causing reversion—where exhaust gases flow back into the cylinder during the intake stroke, hindering engine performance. These potential issues highlight why upgraded valve springs are essential for modified engines!
The XDP Performance Valve Springs and Retainer Kit XD389 features a conical design that offers improved valve control compared to basic straight springs. This innovative conical shape allows for a smaller, lighter weight spring retainer that is more robust due to its reduced size. Unlike other aftermarket valve springs, the XD313 Valve Spring Kit is compatible with a wide range of applications, from stock to race-built engines, making these springs a perfect one-and-done upgrade that lets you increase your engine’s power potential in the future.
Each spring is subjected to a stress relief process and is computer load mapped, ensuring a superior-quality product with long-term resilience. Tested within 1 lb of seat pressure, this valve spring and retainer set includes locks, retainers, springs, and is backed by XDP's 1-year unlimited mileage warranty.
