Steel C/M Spring Seats - 1.550 x .770 x .575

The PAC Racing Springs Steel C/M Spring Seats (1.550 x .770 x .575) are precision coil-over components designed for serious builders and track-focused suspension engineers. These spring seats serve as the interface between your coilover body and the spring, controlling spring location, preload geometry, and overall suspension stiffness delivery.

Manufactured from hardened steel, these spring seats provide the durability and concentricity required for high-cycle motorsports applications. The 1.550-inch outer diameter accommodates a variety of spring wire diameters, while the .770-inch bore and .575-inch height ensure precise spring positioning and axial alignment. Steel construction resists deformation under extreme preload conditions, maintaining stable spring rates across suspension articulation.

These spring seats are ideal for builders working with PAC Racing Springs coilovers or any aftermarket suspension system that utilizes standard C/M spring seat geometry. Track engineers, chassis dyno tuners, and DIY fabricators will find value in having quality replacement or upgrade seats on hand for suspension tuning and performance enhancements.
