5in. x 16in x 100# Rear Spring

The 5in. x 16in x 100# rear spring from Landrum Springs is a precision coil spring engineered for vehicles requiring controlled vertical compliance and load support at the rear axle. Built for enthusiasts and mechanics who demand predictable handling characteristics and OEM-equivalent performance, this conventional coil spring delivers consistent spring rate across its operating range. Whether you're restoring a classic vehicle, replacing worn OEM springs, or fine-tuning suspension geometry, this rear spring provides the foundation for stable ride quality and improved chassis dynamics.

Constructed from high-strength steel and finished with a durable gold powder coat for corrosion resistance, the 5in. x 16in x 100# spring features a 100 lb/in spring rate—a specification that defines how many pounds of load compress the spring one inch. This moderate rate is ideal for rear suspension applications where balanced ride comfort and load-carrying capacity are priorities. The 5-inch outer diameter and 16-inch compressed length make it compatible with standard mounting hardware found on many domestic and import vehicles. The gold powder coat protects against road salt, moisture, and environmental degradation while allowing easy visual inspection for damage or deformation.

Mechanics and DIY builders choose Landrum Springs coils for their consistent performance and reliability across thousands of suspension cycles. This rear spring suits vehicles experiencing sagging rear ends, uneven load distribution, or inconsistent handling due to fatigued OEM springs. Before installation, verify your vehicle's OEM spring rate and compare it against this 100 lb/in specification—mismatched springs can affect brake balance, steering response, and tire wear. Always replace springs in pairs (left and right) to maintain symmetrical suspension geometry and prevent rollover risk or uneven body attitude.
