1.500 O.D. Spring Shims 100pk .060 Thick .645 ID

The 1.500 O.D. Spring Shims 100pk .060 Thick .645 ID are precision spacers designed for valve spring preload adjustment. These shims are essential for engine builders looking to fine-tune valve spring pressure in various engine applications. Whether you're working on a standard rebuild or a performance upgrade, these shims provide the necessary precision for optimal engine performance.

Manufactured to strict tolerance standards, these spring shims feature a 1.500-inch outer diameter, a 0.645-inch inner bore, and a nominal thickness of 0.060 inches. Their precision-stamped construction ensures consistent flatness and uniform density, which are critical when stacking multiple shims to achieve target pressures. This design helps maintain dimensional accuracy under the extreme conditions encountered during engine operation.

Engine builders and mechanics can rely on these shims for various applications, including naturally aspirated, supercharged, or turbocharged engines. The 100-pack offers ample inventory for complete engine rebuilds or ongoing performance projects, eliminating the need for multiple smaller orders. These shims are compatible with common valve spring configurations, making them a versatile choice for many engine setups.
