Part Number: RS55289

Summary: The Rancho RS5000X Series is engineered to provide superior durability and ride quality for heavy-duty applications. Utilizing a sophisticated twin-tube design with a larger 2.25-inch body, these shocks offer increased fluid capacity to maintain cooler operating temperatures during demanding use. Configured for vehicles with a 4-inch lift, they deliver a smooth street feel while providing the ruggedness required for off-road transitions.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth initial response to ensure comfort during daily driving.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent damping force to ensure reduced aeration and foaming.
• Heavy-Duty Body: A 2.25-inch twin-tube diameter provides increased oil capacity to ensure maximum heat dissipation during towing or hauling.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

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 a 4-inch suspension lift to ensure the piston operates within the correct travel range.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable; if the outer body is dented by a rock or debris, the inner cylinder is protected, allowing the shock to continue functioning properly.

Do these include the mounting hardware?
Yes, these shocks come with the necessary bushings and washers for the S5 upper stud mount and the OE-style lower mount for a direct-fit installation.
