Valve Spring Retainers

The Edelbrock Valve Spring Retainers (Part Number 9736) are precision-engineered components designed for high-performance engine builds requiring reliable valve actuation and spring control. This set of 16 steel retainers features a 7-degree valve seat angle, 1.060-inch step diameter, and 1.460-inch single-spring design, making them compatible with various small-block and mid-block engine platforms. Engineered to handle elevated RPM environments and aggressive cam profiles, these retainers ensure consistent valve train geometry and minimize spring surge at high engine speeds.

The 1.060-inch step specification provides a critical bearing surface for spring seating, while the 7-degree angle matches OEM and aftermarket cylinder head designs. Manufactured from hardened steel, these retainers resist deformation under sustained high-load conditions that occur during sustained throttle, forced induction, or high-RPM applications. The single-spring design accommodates both traditional coil springs and modern dual-spring configurations with proper shimming, offering flexibility for custom valve train tuning. Edelbrock's precision manufacturing tolerances ensure straightness and concentricity, which are essential for even spring preload distribution and extended component longevity.

These retainers are essential for engine builders, performance enthusiasts, and restoration shops working with stroker assemblies, cam upgrades, and modified cylinder heads. Whether assembling a street performance engine, bracket racing application, or vintage rebuild, matching the correct retainer geometry to your specific head and spring combination is critical for valve train stability. The set of 16 provides coverage for typical V-8 engine configurations with one pair of spares, supporting both compression-ignition and spark-ignition platforms requiring aftermarket valve train components.
