The Rancho RS5000X series (RS55150) is a nitrogen-gas-pressurized shock absorber designed to replace worn factory units on full-size GM trucks, SUVs, and vans. Utilizing Rancho’s Cross Tuned technology, this shock features an exclusive rebound valving system and an advanced compression phase to maintain vehicle control while absorbing harsh impacts on and off-road. The twin-tube body is nitrogen-charged to 150 PSI, which reduces aeration and foaming to ensure consistent damping performance under heavy load or high-temperature conditions.

• Durable Construction: Features a 16mm nitro-carburized piston rod to resist scuffs and corrosion, along with a 35mm sintered iron piston for structural integrity.
• Advanced Valving: Progressive Engagement Valving is custom-tuned to reduce initial impacts at low speeds and minimize ride harshness.
• Temperature Resistance: All-weather fluid allows for consistent operation in internal temperatures ranging from -40°F to 248°F.
• Reliable Seals: Fluon-banded piston and self-lubricating seal provide a smoother rebound and quicker response to changing road conditions.
• Hardware Included: Comes with a polyvinyl protective boot and rubber bushings to protect the rod and absorb road vibrations.
