Rancho RS5000X 0-1.5 inches Rear Lift Shocks for 1981 Jeep Scrambler 4WD

Part Number: RS55113

Summary: The Rancho RS5000X series utilizes a Cross Tune Technology system to deliver a significant upgrade in ride quality for your Jeep Scrambler. As a Tier 4 twin-tube shock, it features a unique valving design that reduces harshness and improves handling on both paved roads and light trails. These shocks are specifically configured for 0-1.5 inches of rear lift, providing a durable and dent-resistant solution that maintains smooth street comfort during daily operation.

Features

• Cross Tune Technology: A progressive engagement valving system provides customized damping to ensure a smooth, controlled ride across varying terrain.
• Gas Pressurized Design: Low-pressure nitrogen gas charge provides a reduction in aeration and foaming to ensure consistent performance during extended use.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and outer-wall durability to ensure the internal piston remains functional even if the outer shell is dented.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the shock rod to ensure the seal remains free from debris and contaminants.

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 to 1.5 inches of rear lift to ensure the piston operates within its correct travel range.

What is the benefit of a twin-tube design for my Jeep?
The twin-tube design is ideal for off-road vehicles because the outer tube acts as a shield; if a rock dents the outer body, the inner pressure tube remains unaffected, allowing the shock to continue functioning.

What is “Cross Tune Technology”?
It is a proprietary valving system from Rancho that uses a base valve and a piston valve to provide better control at both high and low speeds, eliminating the “stiff” feeling associated with traditional heavy-duty shocks.
