The Rancho RS5000X Rear Shock is engineered to enhance the suspension performance of your Dodge Dakota (1997–2004) and Dodge Durango (1998–2003). Designed for drivers who demand superior handling both on and off the road, this shock absorber features advanced valving technology that improves ride quality, vehicle control, and durability. Whether you’re tackling rugged terrain or cruising city streets, the RS5000X delivers a smoother, more controlled driving experience with reliable performance under extreme conditions.
Built to withstand harsh environments and temperature fluctuations, the RS5000X is an ideal upgrade for enthusiasts seeking improved suspension response and longevity without sacrificing comfort or control.
Key Features:
Rancho’s RS5000X shocks incorporate innovative technologies tailored to optimize your vehicle’s suspension system. Key features include:
- Exclusive Valving System: Custom-tuned rebound and compression valving for each vehicle application to enhance handling and reduce rough ride impacts.
- Advanced Compression Functionality: Compression Control Valve regulates fluid transfer to absorb impacts smoothly and maintain shock motion control.
- Durable Construction: 16mm nitro-carburized piston rod resists corrosion and scuffs, with double-welded loops at stress points for added strength.
- Temperature Resilience: Large twin-tube design filled with all-weather fluid operates efficiently in temperatures from -40°F to 248°F.
- Reduced Fade: Nitrogen gas pressurized to 150 PSI minimizes air-to-oil mixing, reducing damping fade and foaming during extended use.
- Smooth Ride Components: Polyurethane rebound bumper and rubber bushings absorb harshness, while the fluon-banded piston enhances responsiveness.
- Protective Features: Polyvinyl protective boot shields the piston rod from debris and damage.
- Progressive Engagement Valving: Custom-tuned to reduce initial low-speed impacts, minimizing roughness in everyday driving.
Construction & Design:
The RS5000X rear shock is built with premium materials and precision engineering to ensure long-lasting performance. The piston rod undergoes nitro-carburizing, a heat treatment process that hardens the surface to resist wear and corrosion. The 35mm sintered iron piston provides enhanced structural integrity, allowing for consistent shock motion control under demanding conditions.
The twin-tube body design is filled with a specially formulated all-weather fluid that maintains optimal damping characteristics across a wide temperature range. Double-welded loops reinforce high-stress areas, ensuring the shock absorber withstands rigorous use without failure. Additionally, the polyvinyl boot protects internal components from dirt and moisture, extending service life.
Performance & Sound
By incorporating Rancho’s Cross Tuned technology, the RS5000X shock absorber improves overall vehicle handling and stability. The exclusive rebound valving system and advanced compression phase work together to deliver precise control and reduce unwanted suspension movement. This results in a smoother, quieter ride with less vibration and noise transmitted to the cabin, enhancing driver confidence and comfort.
Installation & Fitment:
The Rancho RS5000X rear shock is designed as a direct replacement for the rear suspension of Dodge Dakota models from 1997 to 2004 and Dodge Durango models from 1998 to 2003. Installation requires no special modifications and can be completed using standard tools. It is recommended to have the shocks installed by a qualified technician to ensure proper fitment and performance.
What's Included:
