Spring Conv Front 5in OD x 9.5in Elite 400lbs

The Spring Conv Front 5in OD x 9.5in Elite 400lbs is a premium front coil spring engineered for performance suspension builds and OEM-replacement applications where precise load control is critical. Built by Landrum Springs, an industry leader in suspension technology, this conventional coil spring delivers the consistent spring rate needed for both street vehicles and competition builds. Whether you're restoring a classic muscle car, upgrading a daily driver, or fine-tuning a track-focused platform, this 400 lb/in spring rate provides the foundation for responsive handling and predictable weight transfer.

This front spring features a 5-inch outer diameter and 9.5-inch free length, making it compatible with many popular suspension geometries and mounting locations. The 400 lb/in spring rate—the force required to compress the spring one inch—balances ride quality with structural support, resisting bottoming under moderate load while maintaining compliance over road imperfections. Constructed from high-carbon steel and finished with a durable silver powder coat, the spring resists corrosion and maintains finish integrity through years of thermal cycling and moisture exposure. The Elite series designation indicates enhanced material selection and stricter tolerances, ensuring consistent performance across the lifespan of your vehicle.

Mechanics and enthusiasts building independent front suspension systems—whether A-arm, strut-based, or control-arm designs—rely on Landrum Springs for repeatable, predictable performance. This spring suits both bolt-on upgrades and complete suspension rebuilds, and works effectively when paired with matched rear springs and quality dampers. Before installation, verify your platform's original spring specifications, ensure proper suspension geometry, and use appropriate spring compressors during removal and installation. The 6.16 lb weight and compact packaging allow straightforward handling and fitment into standard spring perches and mounting brackets.
