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

The Steel C/M Spring Seat - 1.450 x .700 x .570 by PAC RACING SPRINGS is a precision coil-over spring perch engineered for high-performance suspension builds and motorsports applications. This component serves as the load-bearing interface between your coil spring and suspension assembly, ensuring consistent spring rate delivery and eliminating deflection under dynamic driving conditions. Whether you're building a track car, street performance vehicle, or upgrading an existing suspension system, a quality spring seat is fundamental to achieving predictable handling and maximizing your spring investment.

Manufactured from hardened steel, this C/M (coil-over maintenance) spring seat features precision-machined dimensions of 1.450 inches outer diameter, .700 inches inner diameter, and .570 inches height—specs that reflect PAC Racing Springs' commitment to OEM-quality tolerances. The compact 0.045 lbs weight minimizes unsprung mass while the robust steel construction withstands repeated spring compression cycles, thermal cycling, and the lateral loads encountered during aggressive cornering or competition driving. The precisely calculated seat geometry maintains optimal spring concentricity, reducing binding and ensuring linear load transfer throughout the suspension stroke.

This spring seat is ideal for fabricators, suspension tuners, and enthusiasts assembling custom coil-over systems or refurbishing worn original equipment. Mechanics and racers rely on PAC Racing Springs components for their dimensional accuracy and durability in both street and track environments. Installation requires proper centering on the suspension tower or strut housing to prevent lateral loading; verify compatibility with your specific spring diameter and vehicle platform before assembly. Pair this seat with a complementary spring perch, damper body, and properly rated coil spring for a complete, performance-tuned suspension setup.
