Rancho RS5000X 2.5-4″ Lift Shocks for 1987-1991 Chevy V30, V3500 4WD

Part Number: RS55001

Summary: The Rancho RS5000X series utilizes an innovative Cross-Tuned technology to provide a significant upgrade in ride quality for your lifted Chevy or GMC. By employing a progressive engagement valving system, these shocks effectively manage the increased unsprung weight of larger tire and wheel combinations. This twin-tube gas-pressurized design is engineered to deliver smooth street comfort while maintaining the rugged durability required for off-road environments.

Features

• Cross-Tuned Technology: A unique progressive engagement valving system provides custom-tuned damping to ensure controlled handling during both low-speed technical maneuvers and high-speed impacts.
• Gas-Pressurized Twin-Tube: High-pressure nitrogen gas charge provides a consistent oil column to ensure reduced aeration and shock fade during spirited driving.
• 16mm Nitro-Carburized Rod: The heavy-duty 16mm piston rod provides increased structural rigidity and scuff resistance to ensure long-term seal integrity.
• Protective Boot Included: A durable poly-vinyl accordion boot provides a physical barrier against road debris and moisture to ensure the chrome rod remains free of pits and corrosion.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured with the correct extended and collapsed lengths to accommodate vehicles already equipped with a 2.5-4 inch suspension lift.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design offers an outer tube that can take a dent from a rock or debris without affecting the inner piston tube, making it exceptionally durable for off-road use.

Are the boots required for installation?
While the shocks will function without them, the included boots protect the piston rod from contaminants, which is essential for maintaining the life of the internal seals.
