Spring Locator 1.550 O.D .570 I.D. .040 Thickness

The Spring Locator 1.550 O.D .570 I.D. .040 Thickness by COMP CAMS is a precision valve spring locator designed for high-performance engine builders, mechanics, and racing enthusiasts who demand exact valve train geometry. This critical component seats between the valve spring and cylinder head, ensuring proper spring positioning and load distribution during engine assembly and operation. A correctly positioned spring locator prevents premature wear, reduces valve float, and maintains consistent spring pressure across the entire RPM range.

Manufactured from hardened steel, this locator features a 1.550-inch outer diameter and 0.570-inch inner diameter with a 0.040-inch wall thickness, engineered to withstand extreme valve train forces and thermal cycling. The 0.810-inch spring ID accommodates standard performance valve springs while the inside locator design prevents rotational movement and lateral drift during high-RPM operation. COMP CAMS' reputation for engineering precision ensures tight tolerances and consistent bore sizing across each unit in this 16-piece set, critical for multi-cylinder engine builds requiring uniform valve train response.

Professional engine builders and performance shops rely on this spring locator for small-block and modern performance engines where spring rate and valve control are non-negotiable. Installation requires precision boring or honing to exact specifications; improper seating can result in spring misalignment and catastrophic valve failure at sustained high RPM. The 16-piece quantity provides complete coverage for multi-cylinder applications, making this set essential for engine machine shops, restoration facilities, and racing programs demanding OEM-quality valve train geometry.
