Steel C/M Spring Seat - 1.450 x .700 x .570

The Steel C/M Spring Seat – 1.450 x .700 x .570 is a precision valve spring locator engineered for high-performance engine builds where durability and exact tolerances are non-negotiable. Designed for serious enthusiasts, race teams, and engine rebuilders, this chromoly component serves as an internal spring seat that maintains consistent valve spring geometry under extreme operating conditions. Whether you're building a competition engine or restoring a performance platform to factory-plus specifications, this spring seat ensures your valve train remains stable and reliable across the RPM band.

Machined from chromoly steel, the Steel C/M Spring Seat features a 1.450-inch outer diameter, 0.700-inch spring inner diameter, and 0.570-inch inner diameter seat with a 0.060-inch thickness profile optimized for minimal deflection and maximum load transfer. The chromoly material resists fatigue and deformation under cyclic spring pressures, critical when running high-lift camshafts or upgraded valve springs that demand rock-solid locating surfaces. Its compact 4.4 x 0.3 x 7.8-inch footprint and light 0.045-pound weight make it practical for OEM and aftermarket applications without adding unnecessary mass to the valvetrain assembly.

Engine builders and performance shops rely on this spring seat when precision matters most—during full rebuilds, high-horsepower upgrades, or when replacing worn factory components that have compromised valve train stability. Installation is straightforward: the seat locates inside the spring assembly and requires no special tools. This component is essential for anyone upgrading to stiffer springs, aggressive cam profiles, or seeking to eliminate valve float issues in existing platforms. Verify compatibility with your specific engine family and spring specifications before ordering to ensure proper fitment and performance.
