The Monroe 552001~TS Rear Gas-Magnum Severe Service Shock Absorber is engineered to enhance the performance and durability of heavy-duty vehicles operating under demanding conditions. Designed for the rear position, this shock absorber features a 24.74-inch extended length and a 1.97-inch body diameter, providing optimal fit and function for various applications. Its non-adjustable design ensures consistent performance, making it a reliable choice for fleet operations seeking to maintain vehicle stability and ride quality. Constructed with a heavy-duty nitrocarburized rod and sintered iron piston, the Monroe 552001~TS offers superior durability, extending the service life of the shock absorber. The larger bore and 2-inch reserve tube increase fluid capacity, allowing the shock to work efficiently and maintain a controlled ride over extended periods. A nitrogen gas charge maintains tire-to-road contact, improving ride and handling by reducing aeration and shock fade. The shock absorber's design includes a loop welding technique, providing up to 14,100 lbs. (6,395 kg) tensile strength for maximum durability. The 1-3/8-inch bore and 5/8-inch diameter nitrocarburized piston rod offer efficient and consistent control, while the 1-stage valving reacts effectively to a wide range of driving conditions. These features collectively contribute to enhanced vehicle stability, reduced maintenance costs, and improved driver comfort, addressing the operational challenges faced by fleet managers in maintaining vehicle performance under heavy-duty conditions.
