Key Features:

The Rancho RS5000X Rear Shock incorporates several innovative technologies and design elements to optimize suspension performance:

• Exclusive Valving System: Features a unique rebound valving and advanced compression phase for superior handling and shock control.
• Progressive Engagement Valving: Custom-tuned to reduce initial impacts at low speeds, minimizing harshness and improving ride comfort.
• Compression Control Valve: Regulates fluid transfer to absorb impacts smoothly without disc flutter, maintaining precise shock motion control.
• Low-Friction, Self-Lubricating Seal: Retains gas and oil effectively for quicker rebound and smoother compression cycles.
• Durable Piston Rod: 16mm nitro-carburized rod resists scuffs and corrosion for extended service life.
• Large Twin-Tube Body: Filled with all-weather fluid to ensure cooler operation and consistent performance across extreme temperatures (-40 to 248°F).
• Polyurethane Rebound Bumper and Rubber Bushings: Absorb ride harshness and enhance responsiveness to changing road conditions.
• Nitrogen Gas Pressurization: Pressurized to 150 PSI to reduce damping fade and foaming for sustained shock performance.
• Polyvinyl Protective Boot: Shields the shock from debris and environmental damage.

Construction & Design:

The RS5000X is built with high-quality materials and precision engineering to withstand demanding driving conditions. Its 16mm nitro-carburized piston rod offers exceptional resistance to wear and corrosion, while the 35mm sintered iron piston enhances structural integrity for reliable shock motion control. The double-welded loops at stress points provide added durability, ensuring the shock absorber maintains its performance over time. The large twin-tube design filled with all-weather fluid allows the shock to operate efficiently in a wide range of temperatures, preventing overheating and maintaining consistent damping characteristics.

Installation & Fitment:

Designed as a direct replacement for the rear shocks on Dodge Ram 1500 models from 2009 to 2018 and Ram 1500 Classic models from 2019 to 2020, the Rancho RS5000X installs easily with no modifications required.
