Summary: The Rancho RS5000X Series gas-pressurized shocks are engineered to deliver a significant upgrade in ride quality and durability for your GMC R2500. Featuring a cross-tuned twin-tube design, these shocks provide the ideal balance of off-road ruggedness and smooth street comfort. Specifically configured for vehicles with a 1.5-inch rear lift, they ensure proper suspension travel and consistent damping performance under various load conditions.

Features

• Cross-Tuned Technology: A unique valve system provides precise damping control to ensure a smooth, stable ride on both paved surfaces and rough terrain.
• Gas-Pressurization: High-pressure nitrogen gas charge provides reduced aeration and foaming to ensure consistent performance during heavy-duty use.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles that already have 1.5 inches of rear lift to ensure the piston operates within the correct range.

What is the benefit of the RS5000X gas charge?
The nitrogen gas charge minimizes the mixing of air and oil (foaming), which prevents shock fade during rapid suspension cycling.

Is the dust boot included?
Yes, these shocks include a red polyvinyl boot to protect the chrome piston rod from road grime and off-road debris.
