The Gabriel 77808 Max Control Monotube Shock Absorber is engineered to enhance the performance and durability of 1999-2004 Ford F-250 and F-350 Super Duty Rear RWD models. Designed with a single-tube construction, this shock absorber offers superior response and control, ensuring optimal tire contact with the road surface. The larger bore size facilitates quicker reactions, contributing to a smoother and more comfortable ride. The super-finished chromed piston rod provides a consistent wear surface, enhancing seal lubrication and extending the product's lifespan. Additionally, the high-pressure nitrogen gas and floating piston technology enable immediate response to steering inputs, delivering exceptional handling. The external rod seal effectively keeps out debris, maintaining performance under various conditions. The Drawn-Over-Mandrel (D.O.M.) tubing reduces internal wear, further prolonging the shock absorber's service life. This product is a direct replacement for the original equipment, ensuring a seamless fit and reliable performance.
