Conv Rear Spring 5in x 13in x 250

The Conv Rear Spring 5in x 13in x 250 by Integra Shocks is a precision-engineered suspension component designed for vehicles requiring reliable load support and consistent ride quality. Whether you're upgrading a daily driver, preparing a project vehicle, or maintaining fleet equipment, this conventional rear spring delivers the predictable performance mechanics and enthusiasts depend on.

Built by Integra Shocks—a trusted name in suspension engineering—this spring addresses the common need for stable, progressive spring rates that handle both highway driving and demanding terrain. This rear spring features a 250 lb/in spring rate with a free length of 5.3 inches and a compressed travel of 13.4 inches, making it suitable for applications where moderate to mid-range load capacity is essential.

The compact 5-inch coil diameter maximizes packaging efficiency in tight rear suspension bays while maintaining structural rigidity. The 7 lb weight keeps unsprung mass reasonable, which benefits both handling response and tire contact patch consistency over varied surfaces. This spring suits builders and mechanics working with independent rear suspension (IRS) systems, coilover conversions, or custom suspension geometries where OEM springs fall short.
