2002–2010 Dodge Ram 1500 Laramie, SLT, Sport, SRT-10, ST
RS55281
Overview:
The Rancho RS5000X Front Suspension Shock is engineered to enhance the handling and ride quality of most Dodge Ram 1500 models from 2002 through 2010. Designed for drivers who demand superior on- and off-road performance, this shock absorber features advanced valving technology that improves vehicle control, reduces ride harshness, and maintains consistent damping under a variety of driving conditions. Whether navigating rugged trails or cruising city streets, the RS5000X delivers a smoother, more controlled ride that enhances both comfort and safety.
Built with durability and longevity in mind, this shock absorber is an ideal upgrade for Dodge Ram owners seeking reliable suspension performance that withstands extreme temperatures and challenging terrain.
Key Features:
The Rancho RS5000X shock incorporates several innovative technologies and design elements to optimize suspension performance:
- Exclusive Valving System: Features a unique rebound valving system and advanced compression phase for improved handling and responsiveness.
- Progressive Engagement Valving: Custom-tuned to reduce initial impacts at low speeds, minimizing rough ride sensations.
- Compression Control Valve: Regulates fluid transfer to absorb impacts smoothly without disc flutter, maintaining shock motion control.
- Nitrogen Gas Pressurization: Pressurized to 150 PSI to reduce air-to-oil mixture, minimizing damping fade and foaming for consistent performance.
- All-Weather Fluid: Large twin-tube body filled with fluid that withstands temperatures from -40°F to 248°F, ensuring cooler operation and reliable control.
- Durable Construction: 16mm nitro-carburized piston rod resists corrosion and scuffs, while double-welded loops and a 35mm sintered iron piston enhance structural integrity.
- Protective Polyvinyl Boot: Shields the shock from debris and environmental damage for extended service life.
- Ride Comfort Enhancements: Polyurethane rebound bumper and rubber bushings absorb harshness, while a fluon-banded piston improves responsiveness to road conditions.
Construction & Design:
The RS5000X shock absorber is engineered with premium materials and precision manufacturing to ensure durability and reliable performance. Its 16mm nitro-carburized piston rod offers exceptional resistance to wear and corrosion, critical for maintaining smooth operation over time. The 35mm sintered iron piston provides enhanced structural strength, while the double-welded loops at stress points increase toughness under demanding conditions.
The shock’s large twin-tube design is filled with specialized all-weather fluid that maintains optimal viscosity across a wide temperature range, preventing overheating and ensuring consistent damping. A polyvinyl protective boot guards against dirt and debris, extending the shock’s lifespan and maintaining performance integrity.
Performance & Sound
With its advanced valving and nitrogen gas pressurization, the Rancho RS5000X shock absorber delivers improved vehicle control and handling stability both on paved roads and off-road trails. The shock’s design minimizes damping fade and foaming, ensuring consistent performance during extended use. Additionally, the polyurethane rebound bumper and rubber bushings reduce ride harshness, contributing to a quieter, smoother driving experience without compromising responsiveness.
Installation & Fitment:
The Rancho RS5000X is designed as a direct replacement for front suspension shocks on Dodge Ram 1500 models from 2002 to 2010, including Laramie, SLT, Sport, SRT-10, and ST trims. Installation requires no modifications, fitting seamlessly with existing mounting points and hardware. This makes it a straightforward upgrade for owners seeking enhanced suspension performance without the need for custom fabrication or additional components.
