Hyperco: Motorsport-Proven Suspension Springs for Every Build
Since 1965, Hyperco has been engineering some of the most precisely wound, performance-oriented suspension springs in the world. Founded and still privately held, Hyperco operates out of Pontotoc, Mississippi, and carries a legacy built on the unforgiving demands of professional motorsports. That racing DNA flows directly into every spring the company produces — whether it ends up on a dedicated track car, a weekend off-roader, or a high-performance street build.
What sets Hyperco apart from mass-market spring manufacturers is the consistency of their manufacturing tolerances. Competitive motorsports leave no room for variance: a spring rated at a specific rate needs to perform exactly at that rate, lap after lap. Hyperco has built its reputation by delivering that level of precision, which is why their springs have appeared in IndyCar, NASCAR, road racing, and off-road racing applications for decades. That same technology is packaged for the performance enthusiast market, giving everyday builders access to race-shop quality components.
A Complete Range of Spring Solutions
Hyperco's catalog is broader than many enthusiasts realize. Their coil springs form the backbone of the lineup, covering an enormous range of rates, free lengths, and diameters to suit conventional suspension systems and coil-over conversion setups alike. Whether you're corner-weighting a road race car or dialing in a street performance build, Hyperco coil springs are available in the precise specifications needed to get the job done right.
For truck and off-road applications where stock springs need a boost without a full replacement, Hyperco offers both leaf helper springs and coil helper springs — practical add-on solutions that improve load capacity and reduce sag under heavy use. These helper springs complement factory suspension systems, making them a cost-effective upgrade for towing, hauling, or aggressive trail use.
Builders who want a matched, tuned pair right out of the box will appreciate Hyperco's coil spring sets, which are sold as balanced pairs to ensure side-to-side consistency — a detail that matters enormously on any performance-oriented vehicle. Rounding out the hardware side of the lineup, Hyperco also manufactures leaf spring perches and other mounting accessories to ensure springs are properly seated and secured, completing the suspension system with the same attention to detail as the springs themselves.
Why Builders Trust Hyperco
Hyperco's product range extends well beyond basic replacement springs. Their composite leaf spring technology, specialty spring components, and wide variety of coil-over-compatible springs reflect a brand that has kept pace with the evolving demands of both professional race teams and the performance aftermarket. With nearly 400 products in their catalog, there is a Hyperco spring specification for virtually any chassis, corner weight target, or ride height goal. For suspension tuning, few brands offer the combination of motorsport pedigree, manufacturing precision, and catalog depth that Hyperco brings to the table.
