The Rancho RS5000X series shock absorber features an advanced Cross Tuned technology system, combining a unique rebound valving system with an enhanced compression phase. Designed to improve handling and control both on and off-road, this nitrogen gas-pressurized shock uses a 150 PSI charge to minimize air-to-oil mixture, effectively reducing damping performance fade and foaming under heavy use.

• Precision Valving: Progressive Engagement Valving (PEV) is custom-tuned to reduce initial impacts at low speeds while maintaining control during aggressive motion.
• Advanced Piston Design: A 35mm sintered iron piston with a fluon-banded seal provides enhanced structural integrity and consistent responsiveness to changing road conditions.
