• Recommended for use with new retainers during valve installation to ensure proper assembly
• Manufactured in the USA with strict quality control for consistent performance

Construction & Design:

This valve spring shim is crafted from premium chromoly steel, a material known for its excellent strength-to-weight ratio and resistance to fatigue under high-stress conditions. The precise dimensions ensure a perfect fit within the valve spring assembly, maintaining the correct spring height and tension critical for valve train stability.

The shim’s robust construction helps it withstand the repeated compressive forces encountered during engine operation, reducing the risk of deformation or failure. Its smooth finish and dimensional accuracy contribute to consistent valve spring performance and longer engine component life.

Installation & Fitment:

The Melling valve spring shim is designed for straightforward installation in compatible Chrysler, Dodge, Jeep, and Ram engines. It fits a wide range of models from 2002 through 2026, including popular vehicles such as the Chrysler 300, Dodge Ram trucks, Durango, Charger, Challenger, Jeep Grand Cherokee, Wrangler, and Ram 1500/2500/3500 series.

Installation typically requires removal of the valve springs and retainers. Melling recommends using new retainers when installing this shim, whether on reclaimed or new valves, to ensure proper valve train geometry and secure assembly. No modifications are necessary, making it an ideal direct replacement or upgrade part.
