Monroe 58552 Load Adjusting Shock Absorber

Product Details

The Monroe Load Adjusting Shock Absorber line is built for light trucks that carry varying loads. The calibrated spring adds support as demand increases, helping the suspension maintain more consistent control over rough pavement, cargo weight shifts, and trailer tongue load. Monroe 58552 is a front shock absorber assembly with a metal dust shield and loop bushing/sleeve mounts for the listed Chevrolet and GMC applications.

This part cross-references Gates 34036 and 43107 for the same application.

What It Helps Address

• Front-end sag when towing or hauling
• Excessive bounce after load changes
• Reduced control on uneven roads with cargo onboard
• Suspension instability in older 4x4 trucks and SUVs
• Wear from operating a vehicle with varying front axle load

Installation Notes

Verify compressed length, extended length, and mounting codes before installation. Monroe 58552 uses upper LS41 and lower LS37 loop bushing and sleeve mounts, so confirm the sleeve dimensions match the vehicle’s original mounting points. This part fits front positions only and is listed for vehicles without factory equipped quad shocks where noted in the fitment data.
