Rear Load-Adjusting Shock Absorber and Coil Spring Assembly

The Monroe MON-58640 is a rear load-adjusting shock absorber and coil spring assembly engineered to enhance the capability of Dodge Ram 1500 trucks, particularly when towing or hauling. This assembly incorporates a heavy-gauge, calibrated coil spring that automatically adjusts to the vehicle's load, providing up to 1,100 lbs. of additional load-carrying capacity. Unlike older air shock designs, these load-adjusting shocks are virtually trouble-free, requiring no manual adjustments or air lines, and are built with modern technology for superior durability. They feature aluminum collars for increased strength. Key specifications include a compressed length of 400mm (15.75 inches) and an extended length of 673.1mm (26.5 inches). The mount type for both the upper and lower ends is a Loop Bushing and Sleeve Mount, with a sleeve ID of 9/16 inches and an OAL of 1.5/8 inches. The dust shield is metal and included, while hydraulic lockout, bump stop, and internal rebound bumper are not featured. This product is specifically designed for the rear position of Dodge Ram 1500 models from 2002 to 2008. It is suitable for various trims including Custom, Laramie, and SLT, and for both RWD and 4WD configurations, as well as different engine sizes (3.7L, 4.7L, 5.7L) and cab types (Crew Cab, Standard Cab) within those years. It is intended for towing and hauling applications. It's important to note that the actual load carrying ability is limited by the vehicle's suspension, tires, and transmission.
