Hyperco 2.25″ I.D. x 9″ Free Length Coilover Springs

Hyperco high-performance coil-over springs, or “Hypercoils” are the benchmark in motorsport suspension. These 2.25″ (57.1 mm) inside diameter, 9″ (228.6 mm) free length springs (Hyperco A series) are precision CNC-wound from premium high-tensile alloy steel and 100% load-tested for accurate, repeatable spring rates that hold true throughout their travel — so the rate on the label is the rate on the car.

Compared to conventional suspension springs, Hyperco coil-over springs provide more usable deflection and weigh less, reducing unsprung and overall vehicle weight. The 2.25″ I.D. suits coilover kits and threaded-body shocks built around a 2.25″ I.D. spring seat (verify your perch/slider).

Choose Your Spring Rate

Select your required spring rate from the dropdown. This 2.25″ x 9″ family is offered in rates from 130 lbs/in (23 N/mm) up through 600 lbs/in (105 N/mm). Use the rate specified by your chassis setup sheet or suspension tuner. Each spring is sold individually; most applications use them in matched pairs.
