Repalcement Spring Seat Cup Ford/Mopar

The Edelbrock Replacement Spring Seat Cup for Ford and Mopar engines is a precision valve train component engineered to properly locate and support valve springs during operation. This outside spring seat locator maintains correct spring geometry and preload, which are critical to consistent valve actuation across the entire RPM range. The set of 16 cups ensures you have complete coverage for a full engine rebuild or restoration project.

Manufactured from durable steel, each cup features a 0.060-inch thickness with a 1.700-inch outer diameter and 0.565-inch inner diameter, designed to accommodate a 1.550-inch spring outer diameter. These dimensions are critical: they ensure that valve springs seat squarely on the cylinder head, preventing binding, cocking, or uneven load distribution that would compromise spring life and engine reliability. Proper spring seating is non-negotiable in performance builds where sustained RPM and high valve lift demand consistent spring function.

This replacement spring seat cup is essential for engine builders and restoration specialists working on Ford and Mopar platforms. Whether assembling a stock rebuild, a classic muscle car restoration, or a performance application, these locators are fundamental to achieving valve train stability. Engine builders rely on quality spring seats to prevent valve recession, reduce coil bind risk, and maintain the engineered preload that the cam profile and spring design require.

Edelbrock's engineering expertise in cylinder head flow and valve train dynamics has made the brand a standard reference in the rebuild community. This spring seat cup carries the precision tolerances expected from a manufacturer that understands that small components deliver big results in engine reliability and performance consistency.
