Conventional Front Coil-Over Spring for 18Z0900-12 Black 5.5 O.D.12 Free Length Steel

This Hyperco coil spring is a conventional style front spring with a 5.5-inch outer diameter, a 12-inch free length, and a 900-pound spring rate. The spring features a great-looking blue powder coat finish and is made from high-quality steel.

The spring's design includes both ends closed and ground flat, bringing the closed-end NASCAR-style spring technology to the Hyperco conventional spring line. With traditionally designed, open-pitch coils, very little contact is made with the riser, meaning that very little of the end of the coil will deaden out during the early portion of spring deflection.

The closed-end design of Hyperco's high-travel conventional front spring directly impacts the number of active coils that deflect during spring compression, creating a very progressive spring rate through the initial stages of deflection. This means that the static load is reached with less spring deflection, leaving more on-track dynamic travel and enabling more aggressive and faster set-ups.

The Hyperco conventional-type front coil spring has an overall free length of 12 inches and a spring rate of 900 pounds. It features a blue powder coat finish and is constructed from high-quality steel. The spring is backed by a limited lifetime warranty, ensuring its durability and performance.

In summary, the Hyperco conventional-style front spring offers a unique blend of design features that set it apart from traditional coil springs. Its closed-end design, high-quality construction, and progressive spring rate make it an attractive choice for racers and performance enthusiasts seeking a reliable and high-performing suspension component.
