Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1969-1991 GMC Suburban 1500 4WD

Part Number: RS55112

Summary: The Rancho RS5000X series leverages a unique Progressive Engagement Valving system to provide a smooth, controlled ride for lifted applications. Designed specifically for the GMC Suburban 1500 4WD, these twin-tube gas-pressurized shocks offer exceptional durability and dent resistance for off-road environments. By minimizing aeration and foaming, these shocks ensure consistent damping performance whether you are navigating highway expansion joints or rugged trails.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides increased control during high-velocity impacts to ensure a smooth transition between comfort and performance.
• Twin-Tube Gas Pressure: The 150 PSI nitrogen gas charge provides a consistent damping force to ensure reduced aeration and shock fade.
• Heavy-Duty Body: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during extended use.
• Nitro-Carburized Piston Rod: The 16mm hardened rod provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.

Technical Specifications

Fitment

• 1969-1991 GMC Suburban 1500 4WD
• Note: Configured for vehicles with 2.5 to 4 inches of rear lift height.

What’s Included

• Includes 2 Shocks

• Necessary Mounting Bushings

Why Choose This Product?

• Engineering Advantage: Rancho’s patented cross-tuned technology balances low-velocity comfort with high-velocity control through precision-engineered valving.
• Performance Benefit: The twin-tube design is inherently more resistant to trail damage, as a dent in the outer shell will not restrict the inner piston’s movement.

Frequently Asked Questions

Will these shocks lift my GMC Suburban?
No, these shocks do not create lift. They are specifically configured to accommodate the increased travel requirements of a vehicle already equipped with a 2.5-4 inch suspension lift.

What is the benefit of the RS5000X over a standard shock?
The RS5000X features a larger body and a unique valving system that engages more firmly during aggressive driving while remaining supple during normal street cruising.

Are the dust boots included?
Yes, this pair includes Rancho’s signature red protective boots to shield the piston rods from debris and contaminants.
