Overview:
The Melling High Performance Valve Spring Shim is an essential component designed to optimize the valve spring geometry in high-output Chrysler, Dodge, Jeep, and Ram engines. Crafted for enthusiasts and professional builders alike, this shim ensures precise valve spring alignment and consistent valve train performance under demanding conditions. Whether upgrading or maintaining your 5.7L Hemi, 6.1L SRT8, 6.4L 392, or 6.2L Hellcat and Trackhawk engines, these shims provide the reliability and durability needed for peak engine operation.
Manufactured in the USA with premium materials, Melling’s valve spring shims meet or exceed OEM specifications, making them a trusted choice for performance builds and rebuilds. They are designed to work seamlessly with new or reclaimed engine valves, helping to maintain optimal valve spring pressure and extend component life.
Key Features:
Engineered for precision and durability, the Melling valve spring shims offer the following key features:
- Constructed from high-grade chromoly steel for superior strength and wear resistance
- Thickness of 0.015 inches (0.38 mm) to provide accurate valve spring preload adjustment
- Inside diameter of 0.511 inches (13.00 mm) and outside diameter of 1.259 inches (32.00 mm) for a precise fit
- Universal fitment across multiple Chrysler, Dodge, Jeep, and Ram V8 engines with Hemi and SRT configurations
- Manufactured to meet or exceed OEM quality standards for consistent performance
- Designed to maintain optimal valve train geometry, reducing wear and improving valve spring longevity
- Recommended for use with new retainers to ensure secure installation and reliable operation
- Made in the USA, ensuring quality craftsmanship and material integrity
Construction & Design:
The Melling valve spring shims are precision-engineered from chromoly steel, a material known for its excellent strength-to-weight ratio and resistance to fatigue. This ensures the shim maintains its shape and thickness under the high stresses of valve spring operation. The carefully controlled dimensions, including a 0.015-inch thickness and accurately sized inner and outer diameters, guarantee a perfect fit within the valve spring assembly.
These shims are designed without a raised center, allowing for uniform contact and load distribution across the valve spring retainer. This design consideration helps prevent premature wear and contributes to consistent valve train performance over time.
Installation & Fitment:
Installation of the Melling High Performance Valve Spring Shim is straightforward for experienced engine builders and mechanics. It is recommended to use new valve spring retainers when installing these shims, whether on new or reclaimed valves, to ensure proper seating and secure retention. The shim fits directly between the valve spring and retainer, allowing for precise adjustment of valve spring height and preload.
This shim is compatible with a wide range of vehicles equipped with Chrysler, Dodge, Jeep, and Ram V8 engines, including:
- 2005–2024 Chrysler 300
- 2002–2010 Dodge Ram, 2011–2026 Dodge Durango
- 2006–2023 Dodge Charger and Challenger
- 2005–2011 Dodge Dakota and 2005–2008 Dodge Magnum
- 2005–2010 Jeep Commander and Grand Cherokee, 2011–2026 Jeep Grand Cherokee, Wrangler, Wagoneer
- 2011–2026 Ram 1500, 2500, and 3500 models
This extensive fitment ensures versatility for a variety of performance and restoration projects involving Hemi and SRT engines.
What's Included:
- Melling High Performance Valve Spring Shim (0.015 inch thickness)
Ideal For:
This valve spring shim is ideal for automotive enthusiasts, professional engine builders, and mechanics who demand precise valve train geometry and enhanced durability in high-performance Chrysler, Dodge, Jeep, and Ram engines. It is especially suited for those upgrading or maintaining 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat or Trackhawk engines where valve spring performance is critical.
