The 1.480 O.D. Spring Shim Kit by COMP CAMS is a vital component for adjusting valve spring pressure in high-performance engine builds. This kit includes 16 individual shims in three thicknesses (.015", .030", and .060") designed to help engine builders achieve precise spring rates without the need for complete spring assembly replacements. It's perfect for those working on street performance engines, track-ready setups, or new cam installations.
These spring shims adjust the pre-load on valve springs, which directly influences spring pressure in both closed and open positions. COMP CAMS shims are manufactured to strict tolerances, ensuring compatibility with standard 1.480 O.D. spring seats commonly found in small-block and big-block engines. This allows for fine-tuning of valve control and helps prevent coil bind.
Engine builders, performance enthusiasts, and mechanics will find this kit invaluable for its flexibility during cam installations or spring upgrades. Proper spring pressure is essential for maintaining performance, especially with aggressive cam profiles, as inadequate pressure can lead to valve float and power loss, while excessive pressure can cause premature wear.
