RS55367

Overview:

The Rancho RS5000X Rear Shock is engineered specifically for Dodge Ram 1500 models from 2009 through 2018 and Ram 1500 Classic models from 2019 to 2024. 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. Ideal for Ram owners seeking durable, reliable suspension upgrades, the RS5000X delivers consistent performance across a variety of driving conditions.

With its unique valving system and precision-tuned compression control, the RS5000X shock absorber offers superior control over suspension movement, reducing harshness and improving stability. Whether navigating rough trails or cruising highways, this shock helps maintain vehicle composure and driver confidence.

Key Features:

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

• Exclusive Valving System: Cross Tuned technology with a rebound valving system and advanced compression phase for improved handling on and off road.
• Compression Control Valve: Custom-tuned for each vehicle to regulate fluid transfer, absorb impacts smoothly, and maintain shock motion control without disc flutter.
• Progressive Engagement Valving: Reduces initial impacts at low speeds to minimize rough ride sensations.
• Durable Construction: 16mm nitro-carburized piston rod resists corrosion and scuffs, paired with a 35mm sintered iron piston for enhanced structural integrity.
• Low-Friction Seals: Self-lubricating seals retain gas and oil for quicker rebound and smoother compression.
• All-Weather Fluid: Twin-tube body filled with fluid that withstands extreme temperatures from -40 to 248°F, ensuring consistent performance.
• Polyurethane Rebound Bumper and Rubber Bushings: Absorb ride harshness and improve responsiveness to changing road conditions.
• Nitrogen Gas Pressurization: Pressurized to 150 PSI to reduce air-to-oil mixing, minimizing damping fade and foaming.
• Protective Polyvinyl Boot: Shields the shock shaft from debris and environmental damage.
• Limited Lifetime Warranty: Backed by Rancho’s commitment to quality and durability.

Construction & Design:

The RS5000X rear shock is built with high-quality materials and precision engineering to withstand demanding driving environments. The 16mm piston rod undergoes nitro-carburizing, a heat treatment process that enhances surface hardness and corrosion resistance, ensuring long-lasting durability. The 35mm sintered iron piston provides robust structural support, while the twin-tube design filled with all-weather fluid maintains optimal operating temperatures even in extreme climates.

Low-friction, self-lubricating seals improve shock responsiveness by retaining gas and oil, enabling quicker rebound and smoother compression cycles. The polyvinyl protective boot guards against dirt and debris, extending the service life of the shock absorber. Rubber bushings and a polyurethane rebound bumper further contribute to ride comfort by absorbing vibrations and harsh impacts.

Installation & Fitment:

The Rancho RS5000X Rear Shock is a direct replacement for the rear shocks on Dodge Ram 1500 models from 2009 to 2018 and Ram 1500 Classic models from 2019 to 2024. Installation requires no modifications, fitting seamlessly with factory mounting points for a straightforward upgrade. Professional installation is recommended to ensure proper torque specifications and alignment for optimal performance and safety.
