5in. x 16in x 300# Rear Spring

The Landrum Springs 5-inch OD x 16-inch Rear Coil Spring (K16-300) is a Gold Series conventional coil spring engineered for rear suspension applications requiring a 300 lb/in spring rate. Built from high-grade steel with a gold powder coat finish, this spring delivers consistent load support and damping characteristics essential for vehicle suspension tuning, whether for street performance, autocross applications, or specialized automotive setups.

The 300 lb/in spring rate defines how much force is required to compress the spring one inch—a moderate-to-stiff rate suitable for vehicles seeking improved handling without sacrificing ride comfort entirely. At 16 inches in length with a 5-inch outer diameter, this rear spring integrates into suspension geometries where space and load-bearing characteristics are precisely matched. The gold powder coat provides both corrosion resistance and visual identification, common in Landrum's Gold Series lineup. Weighing 10.05 lbs, the spring is substantial enough to handle sustained loads while maintaining the predictable, linear behavior expected from conventional coil spring designs.

This Landrum Springs rear coil spring is ideal for builders and technicians upgrading suspension systems on vehicles where OEM springs no longer meet performance requirements. The 300 lb/in rate works well for vehicles with moderate weight increases, lifting kits, or those transitioning from soft stock springs to more responsive setups. Proper spring selection depends on vehicle weight, intended use, and complementary damping components—ensuring that a 300 lb/in rear spring coordinates with matched front rates and shock absorbers for balanced suspension behavior.
