1.270 Valve Spring Shims .570 ID .030 Thick

The 1.270 Valve Spring Shims .570 ID .030 Thick by DURA-BOND are precision-engineered components primarily designed for high-performance engine builders. These shims are critical spacers in valve spring assemblies, allowing technicians to fine-tune spring pressure and preload to exact specifications.

Manufactured to DURA-BOND's exacting tolerances, these shims feature a .570 inner diameter and a .030-inch thickness that integrates seamlessly into standard valve spring stacks. The hardened steel construction ensures durability under cyclic loading, while the precision engineering minimizes run-out and promotes uniform load distribution across the spring seat.

Armorers and performance engine builders rely on DURA-BOND shims to maintain optimal valve train geometry, which is essential for reliability and performance. The 1.270-inch outer diameter is optimized for compatibility with various valve spring assemblies, making these shims a versatile choice for those who demand precision in their applications.
