The Mopar Performance Spacer Package is a precision shim set specifically designed for fine-tuning valve train geometry in Mopar 426 Hemi engine builds and high-performance restorations. This package includes 12 individual round shims that help maintain critical clearances between rocker arms and cylinder heads, making it an essential tool for serious engine builders and restoration shops.
Each shim features an inner diameter of 0.878 inches and a thickness of 0.015 inches, crafted from hardened steel to ensure durability and dimensional stability in high-RPM and high-boost environments. These shims are engineered to address common rocker arm geometry issues, allowing for precise adjustments without the need for a complete valve train redesign.
Professional engine builders, Mopar enthusiasts, and restoration specialists rely on the Spacer Package to achieve optimal pushrod geometry and prevent rocker arm bind. The round profile and precision bore of each shim ensure concentric seating and repeatable performance across multiple installations, making it a vital component for both street and competition applications.
