Rancho RS5000X 2-4″ Lift Shocks for 1966-1977 Ford Bronco 4WD

Part Number: RS55115

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade over factory damping for those seeking a balance between off-road durability and street comfort. Utilizing a cross-tuned twin-tube design, these shocks are configured for 2-4 inch lift heights, effectively managing the increased unsprung weight of larger tire packages. The unique progressive engagement valving ensures a smooth ride during daily transit while providing the necessary resistance to prevent bottoming out during trail use.

Features

• Cross-Tuned Technology: A specialized valve system provides a custom-tuned ride for lifted applications to ensure consistent control on uneven terrain.
• Progressive Engagement Valving: A custom-tuned compression disc works in conjunction with the base valve to provide initial comfort to ensure harsh impacts are absorbed without jarring the chassis.
• Nitro-Carburized Piston Rod: The 16mm heavy-duty rod construction provides superior scuff and corrosion resistance to ensure long-term seal integrity in harsh environments.
• Protective Boot Included: A durable polyvinyl accordion boot provides a physical barrier for the piston rod to ensure debris does not damage the internal seals.

Frequently Asked Questions

Will these shocks lift my Ford Bronco?
No, these shocks do not create lift. They are specifically valved and length-adjusted to function correctly on vehicles already equipped with a 2-4 inch suspension lift kit.

What is the benefit of the twin-tube design for my Bronco?
The twin-tube design is highly durable for off-roading; if the outer body is dented by a rock, the inner cylinder remains unaffected, allowing the shock to continue functioning properly.

Are the boots required for installation?
While the shocks will function without them, the included boots are highly recommended to protect the nitro-carburized rods from rock chips and mud, which extends the life of the seals.
