5in x 16in x 75lb Rear Spring

The 5in x 16in x 75lb rear spring from LANDRUM SPRINGS is a precision-engineered suspension component designed for vehicles requiring custom spring rates and load capacity control. This coil spring is built for enthusiasts and mechanics tackling suspension modifications, whether you're lowering a chassis, adjusting ride height for performance handling, or optimizing weight distribution across an independent rear suspension system.

Manufactured using high-tensile steel, this spring maintains a consistent spring rate across full compression and extension cycles. The 5-inch free length provides the geometry necessary for rear axle travel while minimizing bind and ensuring predictable spring behavior under braking, acceleration, and lateral loads. The 75-pound rate makes this spring ideal for lighter applications or as part of a progressive spring setup where variable load support enhances both ride quality and cornering stability.

This rear spring suits builders working on vintage muscle cars, street rods, and modern performance platforms using custom rear suspension systems. Installation pairs well with quality dampers and control arms, allowing tuners to dial in specific performance characteristics. Its lightweight design at 4.3 lbs ensures structural integrity and fatigue resistance over extended use, making it critical for track days and aggressive street driving.
