The Rancho RS5000X Series shock absorber (RS55118) utilizes an advanced twin-tube gas-pressurized design to deliver consistent performance on and off-road. Engineered with Rancho's exclusive Progressive Engagement Valving, this shock is custom-tuned to reduce initial impacts at low speeds while maintaining control during high-speed compression. The 150 PSI nitrogen gas charge minimizes air-to-oil foaming and damping fade, ensuring the shock maintains its effectiveness during demanding use.
