Valve Spring Shims 1.625in x .060in

The Valve Spring Shims 1.625in x 0.060in by MANLEY are precision-engineered components designed for high-performance engine builds and valve train modifications. These shims are essential for tuners, engine builders, and automotive enthusiasts who demand exact valve spring preload control on both naturally aspirated and forced induction platforms. Proper valve spring shimming is critical to maintaining precise seat pressure and preventing float at elevated RPM.

Manufactured from hardened steel, these shims resist deformation under sustained pressure and thermal cycling, ensuring consistent performance across thousands of combustion cycles. The shims feature a fixed thickness of 0.060 inches, which is suitable for applications requiring mid-range preload adjustment without compromising valve train geometry.

Engine builders working with LS, small-block Chevy, Ford, and Mopar platforms benefit from MANLEY's valve spring shims when transitioning to aggressive aftermarket cams or increasing engine speed limits. Installation involves disassembly of the cylinder head and careful measurement of existing preload to ensure optimal performance.
