Hydraulic Spring Perches

Hyperco’s Hydraulic Spring Perches are suspension components used on coil-over springs designed to minimize lateral forces, resulting in maximized total performance of a vehicle.

Coil springs do not distribute their load evenly around the face of the end coils by nature. This results in lateral load. Hyperco’s hydraulic spring perches eliminate lateral loads by allowing the spring forces to remain centered on the damper.

By precise shaping of the sealing wall of both the spring perch and cylinder body, a perch can freely tilt as needed to evenly distribute the load over the face of the perch. The result is a reduction of bending load on the shock absorber of up to 96%, along with an enhancement in mechanical grip at the tire.
