Description
If you’re building a front-end suspension that demands precision geometry and consistent load support, a properly matched coil spring is non-negotiable. The Hyperco 18Z1100-12 delivers a stiff 1100 lb/in rate in a compact 12-inch package—ideal for drag racing, road course setups, or high-downforce applications where predictable spring behavior translates directly to lap times. This conventional coil design pairs easily with modern dampers and control arms, giving you the foundation for a tuned suspension without compromise.
