Monroe 58648 Shock Absorber and Coil Spring Assembly - Rear

Monroe Load Adjusting Shock Absorber 58648

Monroe 58648 is a rear load adjusting shock absorber for light trucks and vans that tow or carry changing loads. It uses a heavy-gauge calibrated spring to add control as road conditions and vehicle weight become more demanding.

This Monroe Load Adjusting Shock Absorber line is built for vehicles that see frequent towing and hauling duty, helping maintain more consistent rear suspension response under load. It is a direct-fit suspension shock absorber and coil spring assembly for select Dodge Grand Caravan, Chrysler Town & Country, Ram C/V, and Volkswagen Routan rear applications.

Verify rear fitment by year, make, model, and suspension configuration before installation. This part uses LS28 upper and lower mounting codes with loop bushing and sleeve mounts, so confirm sleeve dimensions against the original shock before replacement. This part cross-references Monroe Shocks & Struts (e.g., G64042) for the same application.
