Conv Rear Spring 5in x 13in x 225

The Conv Rear Spring 5in x 13in x 225 by INTEGRA SHOCKS is a heavy-duty coil spring designed for vehicle suspension systems that require reliable load support and consistent ride height. This spring is ideal for mechanics and enthusiasts who are rebuilding independent rear suspension (IRS) setups, whether restoring classic vehicles or upgrading modern performance builds.

With a verified spring rate of 225 pounds and a coil diameter of 5.3 inches, this spring ensures predictable suspension geometry and maintains proper ride height under load without excessive sag. The 13-inch free length provides an optimal compression range for IRS applications, allowing for compact packaging without sacrificing travel. INTEGRA SHOCKS has engineered this spring using heat-treated steel to resist permanent deformation, ensuring years of consistent performance through countless compression cycles.

Technicians working on independent rear suspension systems—particularly Corvettes, Camaros, and other platforms with transverse or multi-link IRS designs—will find this spring essential for enhancing vehicle performance. Its manageable weight of 6.5 pounds allows for straightforward installation and replacement during suspension service, making it suitable for both professional shops and dedicated home mechanics.
