Spring Conv Rear 5.0in OD x 13in Elite 225lbs

The Spring Conv Rear 5.0in OD x 13in Elite 225lbs by Landrum Springs is a premium rear suspension coil spring engineered for vehicles requiring enhanced load capacity and refined ride quality. Built for mechanics and enthusiasts tackling serious suspension upgrades, this spring delivers the stiffness and durability needed in custom builds, lowering applications, and performance restorations. Whether you're fine-tuning a classic hot rod, modifying a truck bed setup, or engineering a street performance platform, this Elite-grade spring provides the foundation for predictable handling and consistent suspension geometry under dynamic driving conditions.

Featuring a 5.0-inch outer diameter and 13-inch length, this coil spring is rated at 225 pounds per inch (lbs/in) of spring rate, providing controlled compression and rebound for rear-end applications. The Elite designation indicates Landrum Springs' premium quality control, tighter coil pitch tolerances, and superior stress-relief processing that extends cycle life and reduces risk of sagging over thousands of miles. At 6.6 pounds, the spring's weight is optimized for minimal unsprung mass while maintaining structural rigidity—critical for maintaining consistent tire contact and suspension response during acceleration, braking, and cornering. The 5.0-inch OD accommodates standard mounting hardware and works seamlessly within conventional rear suspension housings without requiring exotic fabrication.

This spring benefits mechanics building custom rear suspensions, truck owners upgrading payload capacity, and restoration specialists returning vehicles to factory or enhanced ride heights. The 225 lbs/in rate strikes a balance between load support and ride comfort, making it suitable for both street-driven and weekend performance vehicles. Always confirm compatibility with your specific platform's spring perch geometry and existing suspension components before installation; pair this rear spring with a matched front spring set for optimal chassis balance and handling characteristics. Proper alignment and suspension geometry checks following spring installation ensure maximum tire wear life and predictable vehicle dynamics.
