PAC Racing Springs Steel C/M Spring Seats - 1.270 x .640 x .520 are precision-engineered components designed for serious suspension builders and high-performance engine shops. These chromoly steel seats serve as load-bearing interfaces between coil springs and suspension mounting points, ensuring consistent spring rate delivery and eliminating compression loss under dynamic driving conditions.
Constructed from chromoly steel, these spring seats provide superior fatigue resistance compared to standard mild steel, which is critical for handling repeated compression cycles. The precision-machined contact surfaces ensure uniform spring seating, preventing binding, lateral misalignment, or premature wear on spring coils. The compact design helps keep unsprung mass minimal.
Professional installers, suspension fabricators, and DIY tuners will find these seats beneficial for custom spring applications where OEM perches are unavailable or incompatible with aftermarket spring choices. They integrate seamlessly into various suspension setups, including factory-style double-wishbone or MacPherson designs, making them a versatile choice for performance builds.
