The 1.640 O.D. Spring Shims .635 I.D. .030 Thickness are precision-engineered components designed for fine-tuning valve spring assemblies in high-performance engine builds. These shims are essential for adjusting preload, seat pressure, and installed height, which are critical parameters affecting cam profile performance and valve train stability.
With a 1.640-inch outer diameter and .635-inch inner diameter, these shims allow for precise incremental adjustments. The .030-inch thickness enables stacking multiple shims to dial in exact spring pressure curves. Constructed from hardened steel, they resist deformation under high-rpm loads, ensuring consistent preload over time.
Engine builders and automotive enthusiasts can benefit from using these shims to optimize valve spring performance. They are suitable for various applications where valve spring shimming is necessary, providing reliable results across different engine setups.
