Summary: The Rancho RS5000X series leverages advanced CrossTune technology to deliver a significant upgrade in ride quality for your classic 4WD. Designed specifically for vehicles with 0-2 inches of rear lift, these twin-tube shocks provide a perfect balance of on-road comfort and off-road durability. The gas-pressurized design minimizes fluid aeration and foaming, ensuring consistent damping performance whether you are navigating highway miles or rugged trails.

Features

• Gas Pressurization: A high-pressure nitrogen charge provides reduced aeration and foaming to ensure consistent damping performance under heavy use.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with 0-2 inches of rear lift to ensure the piston operates within its optimal travel range.

Is the protective boot included?
Yes, these shocks come with red polyvinyl boots to protect the internal components from dirt, rocks, and road grime.

What is the benefit of the RS5000X gas charge?
The nitrogen gas charge keeps the internal oil under pressure, which prevents the air bubbles (aeration) that typically cause a “spongy” feel and loss of control during rough driving.
