13in. x 5in. x 225# Rear Spring

The 13in. x 5in. x 225# Rear Spring from Landrum Springs is a heavy-duty coil spring engineered for vehicle suspension systems requiring precise load control and consistent ride quality. This rear spring is designed for truck, trailer, and commercial vehicle applications where reliable spring rates are critical to maintaining proper suspension geometry and payload capacity. The 225 lb/in spring rate makes this unit ideal for vehicles carrying moderate to heavy loads while maintaining predictable handling characteristics across various road conditions.

Built from high-strength steel with a durable gold powder coat finish, this conventional coil spring features a 5-inch outer diameter and 13-inch length that fit standard rear suspension mounting locations. The 225 lb/in spring constant delivers predictable compression and extension, resisting sagging under sustained load while minimizing harsh rebound that compromises comfort. Landrum Springs' Gold Series designation reflects quality construction that withstands repeated compression cycles, temperature fluctuations, and corrosive environments. The gold powder coat provides rust resistance and longevity, protecting the steel core from salt, moisture, and chemical exposure common in harsh operating conditions.

This rear spring is ideal for fleet operators, owner-operators, and vehicle enthusiasts restoring or upgrading suspension systems on trucks and utility vehicles. Installation requires proper suspension geometry verification and may necessitate complementary front spring adjustment to maintain balanced ride height and stability. Verify mounting bracket compatibility and suspension type before purchase, as this conventional spring design suits leaf-spring or coil-spring rear suspension architectures. The individual spring unit weighs 6.6 lbs and ships ready for direct installation once proper alignment and fastening procedures are completed.
