Product Details

This Monroe Load Adjusting Shock Absorber is built for rear suspension service on vehicles that see frequent towing and hauling. The spring-assisted design helps the shock respond to added load, giving the suspension more control when cargo weight changes from trip to trip. Monroe 58608 is a direct-fit rear shock option for 1983-2011 Ford Ranger, 2001-2009 Mazda B2300, 1994-2007 Mazda B3000, 1994-2004 Mazda B4000, 1998-2001 Mazda B2500, and 1984-1990 Ford Bronco II applications. This part cross-references Monroe Shocks & Struts (e.g., 43165, 43167) for the same application.

Common Uses

• Rear suspension control when towing trailers
• Improving stability when hauling tools, equipment, or cargo
• Reducing excessive rear-end movement under changing loads
• Supporting trucks that alternate between empty and loaded operation
• Replacing worn rear shocks on Ford Ranger and Mazda B-Series trucks

Installation Notes

Verify compressed length, extended length, and mounting style before installation. Monroe 58608 uses a loop bushing upper mount and a loop bushing with sleeve lower mount, so match the existing hardware and suspension layout on the vehicle. Confirm rear-position fitment for the exact year and model before ordering.

Quality Assurance

Monroe is known for suspension components engineered for real-world truck use, and the Load Adjusting Shock Absorber line is built around a calibrated spring and protective dust shield to support demanding rear suspension service.
