10.5in x 5in x 275# Rear Spring

The 10.5in x 5in x 275# Rear Spring from Landrum Springs is a heavy-duty leaf spring engineered for light-duty trucks, trailers, and custom vehicle builds requiring enhanced load capacity and ride stability. As a mechanic working on suspension upgrades, you'll recognize this spring as a direct replacement or performance upgrade for vehicles needing improved rear-end support, reduced sagging under cargo, and consistent handling characteristics. Landrum Springs manufactures OEM-quality and performance springs using advanced heat-treating processes, making this 275-pound spring ideal for restoring worn suspensions or upgrading vehicles that frequently carry payload.

This rear spring features a 10.5-inch free length and 5-inch width, specifications that define its load rating and deflection curve under compression. The 275-pound rating indicates the spring's resistance to vertical load—higher-rated springs compress less under the same weight, translating to improved anti-squat geometry and better traction during acceleration or braking. Manufactured from high-carbon steel with precise tempering, the spring resists stress corrosion and maintains consistent spring rate across its service life. The compact 5-inch width allows installation in vehicles with space-constrained rear suspensions, while the geometry preserves factory or custom mounting points without requiring frame modifications.

This spring suits mechanics and enthusiasts upgrading pickup trucks, utility vehicles, and custom builds where factory springs have weakened from age or payload cycling. It's particularly effective for vehicles used in towing, hauling, or off-road service where rear-end sag compromises handling and safety. Installation requires removing the axle load, unbolting worn springs, and securing the new spring to existing shackle and mounting hardware—a straightforward bolt-on upgrade requiring no welding or frame fabrication. Verify your vehicle's spring attachment style and mounting width before ordering to ensure compatibility with existing suspension geometry and ride height targets.
