The Rancho RS5000X Series shock absorber is engineered to provide a significant upgrade over factory damping for classic 4WD Dodge and Plymouth trucks. Utilizing exclusive Cross Tuned technology and a progressive engagement valving system, these shocks adapt to varying road conditions to minimize harshness at low speeds while maintaining firm control during high-speed compression. The 150 PSI nitrogen gas charge works in tandem with all-weather fluid to reduce aeration and shock fade, ensuring consistent performance even in temperatures ranging from -40 to 248°F.
