Unmatched Stiffness: Hyperco 650 lb/in Coil Springs

For the most demanding racing setups, the Hyperco 650 lb/in conventional coil spring provides the ultimate in front-end support. Designed with a 9.5-inch length and a 5.5-inch ID, this spring is built for drivers who need maximum stiffness to combat body roll and maintain precise steering geometry. Hyperco’s commitment to engineering excellence means you get a spring that performs consistently under the highest loads.

Superior Features

  • High-stiffness 650 lb/in spring rate
  • 5.5-inch ID for universal fitment
  • 9.5-inch free length
  • Distinctive blue powder coat finish
  • Premium steel construction

The 650 lb/in rate is ideal for high-downforce vehicles or tracks with significant elevation changes where front-end stability is paramount. By minimizing suspension travel, this spring helps keep the chassis flat, allowing for more aggressive cornering and improved tire performance. The blue powder coat finish not only makes a statement in your engine bay or wheel well but also provides a robust barrier against the elements. Whether you are building a dedicated track car or upgrading your existing suspension, Hyperco provides the reliability and performance you demand. Find this and other top-tier components at GGCRACING.
