Product Details
SB-Series Conical Coilover Coil Spring by Hyperco®. Quantity: 1 per Pack. Conical Springs are designed to provide a linear spring rate from free length to solid height while tapering from a 2.5" ID to a 5" OD. They have a 5" OD like a conventional rear spring at one end and a 2.5" ID at the other end as is used on the most popular coil-over springs. The 5" OD body diameter helps prevent bowing issues on these long, light-rate, high-deflection springs. With the proper hardware, they can be used as coil-overs or conventional mount springs. Free lengths were determined to provide the maximum usable travel and spring load without having the ride height too high in the rear.

The racing suspension springs, now known as Hyperco® were pioneered by Jim Fielder in the early 1960s. He was instrumental in developing the spring designs and their dominance in the motor racing industry. The spring designs and technology that originated from Fielder have evolved into what is today known as the Hyperco brand.
