Melling Engine Valve Spring Shim
2002–2026 Chrysler, Dodge, Jeep, Ram 5.7L Hemi / 6.1L SRT8 / 6.4L 392 / 6.2L Hellcat & Trackhawk
471052HP
Overview:
The Melling High Performance Valve Spring Shim is an essential component designed to optimize the valve spring system in a range of Chrysler, Dodge, Jeep, and Ram engines. Crafted to precise specifications, this shim ensures the correct geometry for superior valve train performance, helping maintain proper valve spring pressure and alignment. Ideal for enthusiasts and professional builders upgrading or maintaining high-output HEMI engines, the shim supports reliable operation under demanding conditions.
Manufactured in the USA, this valve spring shim meets or exceeds OEM standards, providing durability and consistent performance. It is compatible with multiple engine variants including the 5.7L Hemi, 6.1L SRT8, 6.4L 392, and the 6.2L Hellcat and Trackhawk powerplants, making it a versatile upgrade or replacement part for a wide range of vehicles.
Key Features:
Designed to enhance valve train geometry and durability, the Melling valve spring shim offers the following key features:
- Constructed from high-quality chromoly steel for strength and longevity
- Precise thickness of 0.015 inches (0.38 mm) to ensure accurate valve spring preload
- Inside diameter of 0.511 inches (13.00 mm) for a secure fit on valve springs
- Outside diameter of 1.259 inches (32.00 mm) to maintain proper spring seating
- Universal fit design compatible with multiple Chrysler, Dodge, Jeep, and Ram engines
- Manufactured to meet or exceed OEM specifications for reliable performance
- Recommended for use with new retainers to optimize valve spring system integrity
- Made in the USA, ensuring quality control and consistency
Construction & Design:
The Melling valve spring shim is engineered from premium chromoly steel, a material known for its excellent strength-to-weight ratio and resistance to fatigue. This ensures the shim can withstand the high stresses and temperatures encountered in performance engine environments. The precise machining of the shim guarantees a perfect fit, maintaining the critical valve spring geometry necessary for optimal engine operation.
Its 0.015-inch thickness is carefully calibrated to provide the correct spacing between the valve spring and retainer, which is crucial for maintaining proper spring tension and preventing valve float at high RPMs. The shim’s dimensions are designed to fit securely without raised centers, promoting even load distribution and durability.
Installation & Fitment:
Installation of the Melling valve spring shim is straightforward for experienced engine builders and mechanics. It is designed to fit a broad range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat or Trackhawk engines from model years 2002 through 2026. For best results, Melling recommends using new valve retainers when installing this shim, whether on reclaimed or new valves, to ensure optimal valve train performance and longevity.
No modifications are typically required, but proper valve spring compressor tools and adherence to manufacturer torque specifications are essential for safe and effective installation.
