VALVE SPRING SHIM KIT, 1.640″ OD, .635″ ID, .015-.030-.060″

Description

Optimize your engine’s valve spring setup with the Comp Cams Valve Spring Shim Kit, designed to deliver precise preload adjustments essential for maintaining valve train stability and performance. Accurate shim selection prevents valve float and spring damage, directly improving engine reliability and efficiency.

This kit includes shims in three thicknesses—.015, .030, and .060 inches—allowing you to fine-tune valve spring tension within tight tolerances. Such incremental thickness options enable exact compensation for wear or component variations, ensuring consistent spring pressure and optimal valve control.

The shims measure 1.640 inches in outer diameter (OD) and .635 inches in inner diameter (ID), dimensions that match standard valve spring seat requirements for broad compatibility with various engine builds. This precise sizing guarantees proper fitment without risk of slippage or misalignment during high-RPM operation.

Constructed by Comp Cams, a leading brand in engine components, this kit weighs 0.4300 kg and has compact dimensions of 10.20 cm length, 4.30 cm width, and 7.10 cm height, making it easy to store and handle within your workshop environment. The robust material composition supports durability under repeated thermal and mechanical stress.

Installing these shims provides a practical solution to valve spring preload discrepancies caused by component wear or modifications. By restoring correct spring tension, you reduce the risk of valve train failure and extend the lifespan of your engine parts, particularly in performance or high-mileage applications.

Engine builders and tuners benefit from the flexibility and precision this kit offers, enabling tailored spring setups that match specific camshaft profiles and operating conditions. The kit’s versatility supports a wide range of engine configurations, enhancing overall powertrain responsiveness and longevity.

Trust the Comp Cams Valve Spring Shim Kit to deliver engineering precision and reliable performance where valve spring control is critical. It’s an essential tool for achieving exact valve spring preload and maintaining peak engine function under demanding conditions.
