Spring Conv Rear 5.0in OD x 16in Elite 75lbs

The Spring Conv Rear 5.0in OD x 16in Elite 75lbs rear coil spring from Landrum Springs is engineered for builders and mechanics who demand precise suspension tuning without compromise. This elite-grade conversion spring replaces factory suspensions in muscle cars, classic hot rods, and modern performance vehicles where stock geometry limits handling potential. Built for rear-end applications, it serves as a critical component in independent rear suspension conversions, air suspension systems, and street-strip builds where load rating and ride quality must be optimized simultaneously.

Manufactured to Elite specifications, this coil spring delivers a 75-pound rate per inch of compression—a moderate spring constant ideal for daily-driven high-performance applications where excessive harshness must be avoided. The 5.0-inch outer diameter and 16-inch compressed length fit snugly in OEM mounting points or custom fabricated perches, while the precise rate ensures predictable weight transfer during acceleration, braking, and cornering. Landrum's manufacturing tolerances guarantee consistency across the spring's travel range, eliminating the dead spots or unpredictable behavior common to inferior aftermarket springs, and the material composition resists fatigue over hundreds of thousands of compression cycles.

Rear coil springs at this specification work best in IRS conversions, four-link rear suspensions, and multi-link independent setups where geometry allows vertical wheel motion without binding. Installers should pair this spring with complementary dampers (shock absorbers or struts) rated for equivalent travel and resistance to achieve balanced suspension dynamics; a 75-pound spring paired with undersized shocks will produce uncontrolled rebound and poor handling. The 4.65-pound weight per unit makes installation straightforward, and clearance checks are essential before final assembly to prevent contact with frame rails, fuel system components, or brake lines during full compression and full extension cycles.
