1.300 Valve Spring Locators .505 ID 16pk

The 1.300 Valve Spring Locators .505 ID 16pk by Straub Technologies Inc. are precision engineered components designed for engine builders, automotive technicians, and performance shops performing valve train assembly and maintenance. These locators serve as critical positioning aids during cylinder head work, ensuring valve springs seat correctly and maintain proper geometry throughout the assembly process. A 16-pack quantity provides sufficient inventory for multiple engine builds or a complete shop stock refresh.

Each locator features a 1.300-inch outside diameter designed to accommodate a 1.300-inch spring OD, with a .505-inch inner diameter bore for precise positioning around valve stems. The .060-inch thickness provides rigid support while remaining lightweight for easy handling during installation. Manufactured from hardened steel, these components resist deformation under spring pressure and repeated use cycles, maintaining dimensional accuracy across hundreds of engine assemblies. The consistent internal diameter ensures repeatable centering of valve springs, which is essential for proper valve lift, duration, and overall engine performance.

Professionals working with small-block and mid-size engines benefit most from this 16-piece set, as the quantity covers multiple cylinder heads or serves as workshop backup inventory. Installation is straightforward: place locators on valve stems before positioning springs and retainers, then remove after final torquing. These locators are compatible with any engine using 1.300-inch OD valve springs and .505-inch stem bores, making them universal across many domestic and import platforms. Whether you're rebuilding classic muscle cars, high-performance engines, or maintaining fleet vehicles, precision valve spring locators are non-negotiable for achieving OEM-spec performance and longevity.
