Key Features:

The Rancho RS9000XL Front Shock combines advanced technology and robust construction to deliver exceptional performance. Key features include:

• Nine-position adjustable damping: Easily customize ride firmness with a simple manual knob for on- and off-road versatility.
• Tri-tube body design: Up to 2.75-inch diameter filled with all-weather fluid ensures cooler operation and consistent damping from -40 to 248°F.
• 18mm nitro-carburized piston rod: Application-specific treatment resists scuffs and corrosion for enhanced durability.
• 1.25-inch sintered iron piston: Provides superior structural integrity and smooth shock absorption.
• 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 responsiveness to changing road conditions.
• Nitrogen gas pressurized to 120 PSI: Minimizes air-to-oil mixture, reducing damping fade and foaming during extended use.
• Long-lasting protective finish: Premium liquid metallic coating and polyvinyl boots shield components from corrosion and debris.

Construction & Design:

The RS9000XL shocks feature a rugged tri-tube design tailored to Jeep Wrangler applications, ensuring optimal fluid flow and heat dissipation. The piston rod undergoes nitro-carburizing, a hardening process that significantly improves surface strength and corrosion resistance, critical for off-road durability. Double-welded loops reinforce stress points, while the sintered iron piston enhances structural integrity under heavy loads.

Seals are engineered for low friction and self-lubrication, maintaining gas and oil retention to provide consistent damping performance. Protective polyvinyl boots guard against dirt and debris, extending shock life in harsh environments. The combination of these materials and engineering choices results in a shock absorber built to endure demanding conditions while delivering smooth, controlled ride quality.

The Rancho RS9000XL Front Shock is a direct-fit replacement for Jeep Wrangler models from 2007 through 2017 and the 2018 Wrangler JK series. Designed for easy installation, these shocks fit both stock and lifted vehicles without requiring modifications. Installation typically involves standard suspension tools and mounting hardware, allowing for a straightforward upgrade that restores or enhances ride control and handling characteristics.
