Rancho RS5000X Rear Shock Absorber for 2015-2022 Chevrolet Colorado and GMC Canyon (RS55023)

Fits 2015-2022 Chevrolet Colorado and GMC Canyon models across all trim levels including Z71, AT4, and Denali.

The Rancho RS5000X RS55023 rear shock absorber uses a unique Progressive Engagement Valving (PEV) system to provide custom-tuned control for your mid-size truck. Designed for both on-road stability and off-road capability, this twin-tube shock features a large body filled with all-weather fluid, allowing it to maintain consistent damping performance in internal temperatures ranging from -40 to 248°F. The system is pressurized with nitrogen gas to 150 PSI to minimize aeration and foaming, significantly reducing shock fade during heavy use.

• Robust Construction: Features a 16mm nitro-carburized piston rod for superior scuff and corrosion resistance, plus double-welded loops at high-stress points.
• Advanced Valving: Cross Tuned technology utilizes a 35mm sintered iron piston and fluon-banding for immediate responsiveness to changing terrain.
• Ride Quality: Polyurethane rebound bumpers and rubber bushings absorb harsh impacts, while a custom-tuned compression control valve regulates fluid transfer without disc flutter.
• Protection: Includes a polyvinyl protective boot to shield the piston rod and oil seal from debris and moisture.
• Manufacturer Part Number: RS55023
