This shock absorber is engineered to withstand extreme temperature fluctuations and harsh off-road abuse, ensuring long-lasting performance and reliability.

Key Features:

The Rancho RS9000XL Rear Shock combines advanced technology and rugged construction to deliver exceptional performance:

• Nine-position adjustable damping: Easily customize ride firmness and control for on-road smoothness or off-road responsiveness with a simple manual knob.
• Tri-tube body design: Up to 2.75-inch diameter filled with all-weather fluid for cooler operation and consistent performance across temperatures from -40°F to 248°F.
• 18mm nitro-carburized piston rod: Application-specific treatment resists scuffs and corrosion, enhancing durability.
• Double-welded loops and sintered iron piston: Reinforced stress areas and a 1.25-inch piston improve structural integrity under heavy loads.
• Low-friction, self-lubricating seal: Retains gas and oil for quicker rebound and smoother compression cycles.
• Polyurethane rebound bumper and bushings: Absorb ride harshness and improve shock responsiveness.
• Nitrogen gas pressurized to 120 PSI: Minimizes air-to-oil mixture, reducing damping fade and foaming during extended use.
• Protective polyvinyl boot and premium liquid metallic finish: Extend shock life by shielding components from dirt and corrosion.

Construction & Design:

The RS9000XL shocks feature a robust tri-tube design that enhances heat dissipation and fluid flow, maintaining consistent damping performance even under extreme conditions. The piston rod undergoes nitro-carburizing, a specialized hardening process that significantly improves resistance to wear and corrosion, critical for off-road environments. Double-welded loops at high-stress points and a heavy-duty sintered iron piston ensure the shock can handle the rigors of towing, hauling, and aggressive trail use.

Additionally, the shock incorporates a low-friction, self-lubricating seal system that preserves internal gas and oil, enabling faster rebound and smoother compression. The polyurethane bumpers and bushings further contribute to ride comfort by absorbing impacts and reducing harshness.
