Rancho RS5000X Shock Absorber (REAR)

2007–2018 Jeep Wrangler / Jeep Wrangler JK

RS55332

Overview:

The Rancho RS5000X rear shock absorber is engineered specifically for Jeep Wrangler models from 2007 through 2018, including the JK series. Designed to enhance both on-road comfort and off-road capability, this shock absorber features advanced valving technology that improves vehicle handling and ride quality. Whether navigating rugged trails or cruising city streets, the RS5000X delivers consistent performance and durability tailored to Jeep enthusiasts seeking reliable suspension upgrades.

Built to withstand harsh conditions and extreme temperatures, this shock absorber offers a smoother, more controlled ride by effectively managing compression and rebound forces. Its robust construction and application-specific tuning ensure optimal shock motion control, making it an ideal choice for Jeep Wrangler owners who demand enhanced suspension performance without sacrificing longevity.

Key Features:

The Rancho RS5000X shock absorber incorporates several innovative technologies and design elements to provide superior handling and durability:

• Exclusive Valving System: Features a unique rebound valving system and advanced compression phase for improved overall handling on and off road.
• Progressive Engagement Valving: Custom-tuned to reduce initial impacts at low speeds, minimizing rough ride sensations.
• Low-Friction, Self-Lubricating Seal: Retains gas and oil for quicker rebound and smoother compression cycles.
• 16mm Nitro-Carburized Piston Rod: Provides superior resistance to scuffs and corrosion for long-lasting durability.
• 35mm Sintered Iron Piston: Enhances structural integrity and shock control.
• Polyurethane Rebound Bumper and Rubber Bushings: Absorb ride harshness and improve responsiveness to changing road conditions.
• Large Twin-Tube Body with All-Weather Fluid: Maintains cooler operation and consistent performance across a wide temperature range (-40 to 248°F).
• Compression Control Valve: Custom-tuned to regulate fluid transfer, preventing disc flutter and maintaining shock motion control.
• Nitrogen Gas Pressurized to 150 PSI: Minimizes air-to-oil mixture, reducing damping fade and foaming for consistent shock performance.
• Polyvinyl Protective Boot: Shields critical components from dirt and debris.

Construction & Design:

The RS5000X rear shock absorber is constructed with high-quality materials and precision engineering to ensure durability and reliable performance. The 16mm piston rod undergoes nitro-carburizing, a heat treatment process that significantly increases surface hardness and corrosion resistance. The 35mm sintered iron piston provides enhanced structural strength, allowing the shock to maintain consistent damping under demanding conditions.

The twin-tube design is filled with all-weather fluid that resists temperature-induced viscosity changes, enabling the shock to operate efficiently in extreme climates. Additionally, the low-friction, self-lubricating seal design helps retain gas and oil, promoting faster rebound and smoother compression for improved ride quality. Protective polyvinyl boots guard against environmental contaminants, extending the service life of the shock absorber.
