Rancho Suspension RS55843 RS5000X Gas Strut Assembly

The Rancho RS5000X RS55843 suspension strut delivers superior on-road and off-road performance through innovative engineering and advanced technology. Featuring Rancho's exclusive Cross Tuned technology, this strut combines a unique rebound valving system with an advanced compression phase to significantly improve handling and vehicle control in any driving condition.

Key Features:

• Cross Tuned Technology: Exclusive rebound valving system and advanced compression phase work together to improve overall handling and performance both on and off-road
• Progressive Engagement Valving: Custom-tuned for each vehicle application to reduce harsh initial impacts at low speeds and minimize rough ride quality
• Twin-Tube Design: Large 2.25-inch diameter body filled with all-weather fluid allows for cooler operation and withstands internal temperatures from -40°F to 248°F
• Nitro-Carburized Piston Rod: 0.625-inch diameter steel rod resists scuffs and corrosion for enhanced durability and longevity
• Sintered Iron Piston: 1.375-inch application-specific piston with fluon banding provides enhanced responsiveness and smoother operation
• Gas Pressurized: Nitrogen gas charged to 60 PSI to minimize air-to-oil mixture, reducing damping fade and foaming
• Low-Friction Seal: Self-lubricating seal retains gas and oil for quicker rebound and smoother compression throughout the shock cycle
• Enhanced Durability: Double-welded loops at stress areas, polyurethane rebound bumper, and protective boot for extended service life

This complete strut assembly includes factory hardware for installation (washers, bushings, and nuts). Backed by Rancho's Limited Lifetime Warranty, the RS5000X series represents decades of suspension engineering expertise from one of the industry's most trusted brands.
