1.480 O.D. Spring Shims .765 I.D. .060 Thickness

The 1.480 O.D. Spring Shims .765 I.D. .060 Thickness from COMP CAMS are precision-engineered valve spring shims designed for engine builders, performance tuners, and automotive technicians who demand exact valve train geometry. These shims serve a critical function in maintaining proper valve spring seat pressure and clearance in high-performance and competition engines. Whether you're rebuilding a stock engine or optimizing a race motor, accurate spring shims are non-negotiable for reliable operation and maximum horsepower delivery.

Manufactured from hardened steel, these valve spring shims feature a 1.480-inch outer diameter, 0.765-inch inner diameter, and 0.060-inch thickness—specifications that allow precise stacking and customization of valve spring pressure curves. The 0.060-inch thickness is a standard measure in the industry, enabling mechanics to fine-tune spring pressure in 0.060-inch increments by layering multiple shims. Steel construction ensures durability under the extreme cyclic loading and temperature fluctuations found in modern engine compartments, preventing deflection or deformation that could compromise valve control and timing accuracy.

This set of 16 shims is ideal for complete engine builds, rebuilds, or multi-cylinder tuning projects where consistent spring pressure across all valves is essential. Professional engine builders and performance shops rely on COMP CAMS shims to dial in precise valve spring loads without compromising quality or repeatability. Installation requires proper spring compressor tools and knowledge of your engine's OEM or target spring pressure specifications; incorrect stacking can result in over- or under-pressured springs, leading to valve float, noise, or accelerated wear. Always consult your engine manual or tuner's specifications before selecting shim thickness and quantity for your application.
