5in OD x 8in FH Rear Spring

The Landrum Springs 5in OD x 8in Rear Spring (model H400) is a conventional coil spring engineered for rear suspension applications requiring a 400 lb/in spring rate. This gold powder-coated steel coil spring delivers consistent load support and ride control across a wide range of vehicle weights and driving conditions, making it a trusted choice for automotive suspension tuning and restoration projects.

The H400's 400 lb/in spring rate provides firm support without excessive stiffness, balancing comfort with handling stability. The 5-inch outside diameter and 8-inch length are designed to fit within standard rear suspension packaging, while the gold powder coat protects against corrosion in varied climates and road conditions. At 4.63 lbs, this single spring integrates cleanly into OEM-style suspension setups or aftermarket systems that call for this load specification.

Rear springs of this specification are used in classic car restoration, performance suspension builds, fleet maintenance, and light-duty truck applications where controlled spring rate is essential. Whether you're replacing a worn OEM spring, upgrading a restoration project, or fine-tuning suspension geometry, the H400 offers predictable performance backed by Landrum's heritage in suspension component manufacturing.

Landrum Springs is recognized for precision coil spring manufacturing. Their Gold Series conventional coil springs are engineered to OEM and performance specifications, making them suitable for both stock replacement and tuning applications. Each spring is sold individually—confirm fitment to your specific vehicle before ordering.
