Hyperco Leaf Spring Perch
Hyperco Hydraulic Leaf Spring Perches: Race-Proven Load Centering
When it comes to extracting maximum performance from a coilover suspension, the spring perch is far more than a simple mechanical seat — it is a critical interface between the spring and damper that directly influences shock longevity, tire contact, and overall handling balance. Hyperco has spent decades engineering solutions to a problem that many builders overlook: the inherent lateral loading that coil springs impose on shock absorbers.
Hyperco's Hydraulic Spring Perches are suspension components used on coil-over springs designed to minimize lateral forces. Coil springs do not distribute their load evenly around the face of the end coils by nature, which results in lateral load on the damper. Left unaddressed, this side loading accelerates shock wear and compromises the damper's ability to do its job consistently lap after lap.
How Hyperco's Hydraulic Technology Works
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 practical result is profound: a reduction of bending load on the shock absorber of up to 96%, along with an enhancement in mechanical grip at the tire.
Hyperco Hydraulic Centering Perches allow the spring end coils to tilt, reducing the bending loads on your shocks. This is especially critical in high-downforce or high-lateral-load applications where suspension geometry is constantly in flux. Hyperco's Hydraulic Spring Perch is designed for remote corner-weight adjustment, making it a Cup, IndyCar, and Pro Time-Attack level tuning tool.
Precision Machined in the USA
Hyperco's hydraulic spring perches are precision-machined in the USA and sold individually, allowing builders to spec exactly the quantity and sizing they need. Perches are available in multiple inner diameter sizes — including 2.00", 2.25", 2.50", and 60mm metric variants — to match a broad range of leaf spring perch and coilover spring configurations.
Applications span open-wheel racing, Trans Am, Formula Ford, Formula Atlantic, quarter midgets, dirt and pavement late models, and motorcycles. This breadth of fitment reflects Hyperco's status as a truly universal supplier across motorsport disciplines.
A Brand Built on Spring Science
Hyperco has engineered precision suspension springs in the USA since 1970, supplying teams in Formula 1, IndyCar, NASCAR, Pirelli World Challenge, and top drift and time-attack programs. For more than 50 years, every Indianapolis 500 winner has won driving with Hyperco suspension springs. That racing heritage flows directly into every spring perch Hyperco produces — these are not afterthought accessories, but components developed alongside the springs they seat.
Hyperco provides high-performance suspension components, including coil over suspension springs, hydraulic load-centering spring perches, and composite leaf springs, with more than 800 race-tested products in the Hyperco catalog as well as products for off-road, power sports, and street performance vehicles. Whether you are building a dedicated race car or upgrading a performance street machine, Hyperco's hydraulic leaf spring perches deliver a measurable, engineering-backed advantage at every corner of the vehicle.
