5in. X 14in. X 275lbs Rear Spring

The 5in. X 14in. X 275lbs Rear Spring from Landrum Springs is engineered for vehicles requiring load-bearing suspension geometry tuned to handle increased chassis weight, towing capacity, or performance modifications. This rear spring is ideal for trucks, SUVs, and heavy-duty platforms where factory springs prove insufficient or deflect excessively under sustained load. Whether you're upgrading a work vehicle, reinforcing a lifted truck, or dialing in a custom build, a properly rated coil spring is fundamental to maintaining ride height, axle geometry, and brake balance—all critical safety factors that affect handling and tire wear.

This Landrum spring features a 275-pound spring rate, meaning it requires 275 pounds of force per inch of compression—a specification that directly controls how the suspension responds to bumps, acceleration loads, and cargo weight. The 5-inch coil diameter and 14-inch free length are standard OEM-compatible proportions, allowing straightforward installation without custom fabrication or frame modifications. Landrum Springs manufactures these coils using high-carbon steel heat-treated for consistency and durability, resisting fatigue failure and maintaining rate consistency across thousands of compression cycles. The compact shipping weight of 8.7 lbs reflects a single-spring unit, making this an economical choice for single-rear or dual-spring setups depending on your suspension architecture.

Mechanics and fabricators favor Landrum springs for diagnostic and replacement work on GM, Ford, and Dodge platforms where rear spring rates commonly range from 250 to 350 lbs/in. This 275-pound rate suits mid-duty applications—perfect for trucks carrying moderate payload without running overly stiff suspension that sacrifices ride comfort or creates bottoming-out risk on articulated terrain. Verify your vehicle's spring pocket dimensions and existing rate before ordering; incorrect spring rates compromise suspension geometry, increase brake dive, and accelerate wear on shocks and bushings. Always replace springs in pairs when possible to maintain balanced load distribution and predictable handling characteristics.
