Rancho RS5000X RS55044 Suspension Shock Absorber

The Rancho RS5000X RS55044 Suspension Shock Absorber is engineered to enhance both on- and off-road driving experiences. Its Cross Tuned technology, featuring a unique rebound valving system and advanced compression phase, improves overall handling and performance. The Progressive Engagement Valving is custom-tuned for each vehicle, helping to reduce initial impacts at low speeds and minimizing a rough ride. Constructed with a 16mm nitro-carburized piston rod and a 35mm sintered iron piston, it offers durability and resistance to corrosion. The twin-tube body, filled with all-weather fluid, allows for cooler operation and increased vehicle control, even in extreme temperatures ranging from -40 to 248°F. Additional features include a polyurethane rebound bumper, rubber bushings for absorbing ride harshness, and a nitrogen gas pressurization to 150 PSI to reduce damping performance fade. This shock absorber is compatible with various models, including the Dodge Ram 2500/3500 and Ford F-250/F-350 Super Duty series. Backed by Rancho’s Limited Lifetime Warranty, the RS55044 is a reliable choice for drivers seeking improved ride quality and vehicle control.
