Coil Spring Conv Rear 13in x 5in x 215lb

The SWIFT SPRINGS Coil Spring Conv Rear 13in x 5in x 215lb (SKU SWI130-500-215TH) is a conventional rear coil spring designed for suspension systems requiring precise load control and consistent spring rate performance. This tight helix coil spring delivers 215 pounds per inch spring rate in a 13-inch length with 5-inch outer diameter, engineered to handle demanding applications where predictable spring behavior directly impacts vehicle handling and load management.

Manufactured from high-strength steel with a durable black powder coat finish, this rear coil spring resists corrosion and wear in both highway and off-road environments. The 215 lb/in spring rate makes this component suitable for mid-range load applications where maintaining ride height and controlling suspension articulation are equally important. The tight helix design ensures reliable performance over extended duty cycles, minimizing spring surge and maintaining consistent damping characteristics. At 12.95 pounds, the spring integrates seamlessly into rear suspension assemblies without introducing unwanted weight penalties.

This rear coil spring serves vehicle platforms requiring OEM-specification or aftermarket suspension upgrades, including light-duty trucks, SUVs, and vehicles transitioning to custom or performance suspension systems. Buyers often pair rear coil springs of this specification with matching front units and upgraded dampers to achieve balanced suspension geometry and improved cornering stability. The 5-inch outer diameter and 13-inch length fit standard rear suspension mounting points found across common domestic and imported platforms.

SWIFT SPRINGS coil springs are recognized in the suspension aftermarket for consistent load-bearing capability and longevity in competitive pricing. The 215 lb/in rate occupies the middle range of typical rear spring rates—softer than heavy-duty springs suited to payload applications, stiffer than passenger comfort-focused designs—making this configuration widely compatible with suspension builders and vehicle owners upgrading from worn OEM springs or seeking mild performance tuning without extreme stiffness.
