Conv Rear Spring 5in x 13in x 225

The Conv Rear Spring 5in x 13in x 225 by INTEGRA SHOCKS is a heavy-duty conventional coil spring engineered for rear suspension systems on trucks, SUVs, and performance vehicles. This replacement or upgrade spring delivers consistent load support and improved ride quality by managing weight distribution and absorbing road impacts. Conventional coil springs like this are the industry standard for vehicles requiring reliable, long-term suspension performance without the complexity of air or adjustable systems.

Built from high-grade steel and finished with a protective black powder coat, this rear spring features a 5-inch outer diameter, 13-inch compressed length, and a 225 lb/in spring rate—meaning it resists compression at 225 pounds per inch of deflection. This spring rate is ideal for moderate to heavy-load applications, providing a balance between comfort and vehicle control. The powder-coated finish resists corrosion and UV damage, extending service life in harsh weather and off-road conditions. At 6.5 pounds per unit, the spring maintains structural integrity while remaining manageable for installation and replacement.

This rear spring is ideal for buyers seeking dependable suspension renewal or load-carrying upgrades for full-size trucks and SUVs. Vehicle owners hauling cargo, towing trailers, or restoring factory suspension will benefit from the predictable performance and durability this spring provides. Installation requires proper alignment and may involve removing wheels and suspension components; consult your vehicle's service manual or a qualified technician to ensure correct fitment and safe operation. The 225 lb/in rate is compatible with vehicles originally engineered for conventional rear springs in this size range.
