The 13in. x 5in. x 325# Rear Spring from Landrum Springs is designed for drivers who require reliable load-carrying capability and consistent ride quality, especially under heavy payload conditions. This purpose-built suspension component is ideal for those who frequently transport tools, tow equipment, or manage lifted platforms.
Constructed from high-carbon steel, this rear spring maintains a consistent spring rate of 325 lbs/inch throughout its load range. This means that for every 325 pounds of load applied, the spring compresses one inch, providing the necessary stiffness to support vehicle weight distribution while ensuring ride comfort on lighter loads. The engineering behind this spring also includes processes for fatigue resistance and longevity, preventing issues like sagging or bottoming out.
This rear spring is suitable for trucks, SUVs, and light commercial vehicles that operate close to their Gross Vehicle Weight Rating (GVWR). Additionally, it benefits enthusiasts looking to build custom suspensions, ensuring predictable handling geometry and minimal suspension sag under dynamic conditions.
