Monroe 58601 Shock Absorber and Coil Spring Assembly - Rear

Load Adjusting Rear Shock for Ford Trucks

Monroe 58601 is a load adjusting shock absorber for rear suspension applications on select Ford trucks. It uses a heavy-gauge calibrated spring to add control as cargo weight or towing demand increases, helping the suspension respond more consistently to changing road and load conditions.

Product Details

Monroe Load Adjusting Shock Absorber 58601 is built for light trucks that tow or carry varying loads. The spring-assisted design adds resistance as demand increases, which helps maintain rear suspension control when the vehicle is working harder. This makes it a practical choice for Ford F-150, Ford F-250, and Ford F-100 Ranger rear applications where load changes are part of normal use. This part cross-references Monroe Shocks & Struts 43167 for the same application.

What It Helps Address

• Rear-end sag when carrying cargo
• Reduced control during towing
• Excessive suspension movement over changing road conditions
• Inconsistent ride behavior between empty and loaded driving
• Wear from frequent hauling demands

Installation Notes and Tips

Verify rear fitment by year, model, and gross vehicle weight rating before installation. Confirm upper and lower mounting styles match the vehicle’s existing shock mounts, and compare compressed and extended lengths to the suspension travel available on the truck. Inspect surrounding suspension components for wear before replacing the shock absorber.

Quality Assurance

Monroe load adjusting shocks are engineered for truck applications that see changing payload and towing conditions. Part number 58601 follows Monroe’s load-adjusting shock design and mounting specifications for the listed Ford rear applications.
