1.625 Valve Spring Locators

The Manley 1.625 Valve Spring Locators are precision engineered components designed for high-performance engine builders and mechanics who demand reliability in critical valve train assemblies. These locators serve as spacers that properly position valve springs on the spring seat, ensuring consistent preload and preventing spring bind or coil separation under aggressive valve lift and high RPM operation. Whether you're building a street performance engine or preparing a race-ready package, correct valve spring locator selection is non-negotiable for durability and consistent cam profile execution.

Manufactured from hardened steel with a black oxide finish for corrosion resistance, the 1.625 Valve Spring Locators feature a precisely machined 0.062 inch thickness that maintains exact spring seat geometry without deflection under load. The design incorporates a 1.570 inch outer diameter that seats cleanly on the spring pad, a 0.567 inch inner diameter for the locator bore, and a 0.860 inch spring ID to accommodate most common valve spring configurations. This set of 16 locators allows for complete coverage on dual overhead cam engines or mixed applications where locator replacement or upgrade is required across both intake and exhaust circuits.

These locators benefit anyone performing valve spring replacement, cylinder head reconditioning, or engine assembly on modern performance platforms. Installation requires careful placement during head assembly to ensure proper spring stack height and avoid valve lash complications. Technicians should verify spring ID compatibility before assembly and confirm that locator thickness matches original equipment or specified build parameters for your specific application, as incorrect locator dimensions can alter valve timing events and compromise engine performance or longevity.
