The 1.640 O.D. Spring Shims .650 I.D. .060 Thickness by COMP CAMS are essential components for tuning valve spring pressure in various engine applications. These shims are designed for mechanics and engine builders who require precise adjustments to valve spring installed height, ensuring optimal performance in both naturally aspirated and forced-induction setups.
Manufactured from durable hardened steel, each shim features a 1.640-inch outer diameter, a .650-inch inner diameter, and a thickness of .060 inches. This common specification allows for stacking, enabling incremental pressure adjustments without the need to replace entire spring assemblies. The precision-engineered tolerances ensure consistent load distribution across the spring seat, which is critical for preventing valve float at high RPMs.
Engine builders, performance shops, and automotive enthusiasts can benefit from using these valve spring shims when upgrading camshaft profiles or correcting factory spring pressures on modified cylinder heads. Their reliable performance and compatibility with various setups make them a valuable addition to any performance tuning toolkit.
