Rancho RS5000X 0″ Rear Lift Shocks for 2002-2009 GMC Envoy with Rear Air Spring

Part Number: RS55386

Summary: The Rancho RS5000X Series gas-pressurized shocks provide a significant upgrade in ride quality for your GMC Envoy or Oldsmobile Bravada. Utilizing a sophisticated twin-tube design with a larger 2.25-inch body, these shocks offer increased fluid capacity to maintain cooler operating temperatures. Specifically tuned for vehicles with rear air springs, they provide the durability and dent resistance required for both daily commuting and light utility use.

Features

• Progressive Engagement Valving: Custom-tuned internal valving provides a smooth initial response to ensure comfort during highway cruising.
• Large Shock Body: The 2.25-inch twin-tube diameter provides increased oil capacity to reduce internal heat buildup and ensure consistent damping performance.
• Gas Pressurization: Nitrogen gas charging provides a reduction in aeration and foaming to ensure immediate response during rapid suspension cycling.
• Heavy-Duty Construction: A 16mm nitro-carburized piston rod provides extra structural rigidity to ensure long-term seal integrity in harsh environments.

Technical Specifications

Fitment

• 2002-2009 GMC Envoy
• 2002-2004 Oldsmobile Bravada
• Note: Fits models equipped with Rear Air Spring only.

What’s Included

• Includes 2 Shocks
• Installation Hardware (where applicable)
• Protective Dust Boots

Why Choose This Product?

• Engineering Advantage: Rancho’s Cross-Sectional Area (CSA) design increases fluid flow within the shock, allowing for better heat dissipation than standard OE replacements.
• Performance Benefit: The twin-tube design is inherently more resistant to trail debris; a dent in the outer tube will not restrict the inner piston’s movement.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks are configured for 0″ of lift and are designed to maintain the factory ride height while improving damping performance.

Do these work with standard coil spring models?
These specific units are valved and designed for vehicles equipped with the Rear Air Spring system found in GMC Envoy and Oldsmobile Bravada models.

What is the benefit of the RS5000X over a standard shock?
The RS5000X features a larger body and gas pressurization, which prevents the “fading” feeling often experienced with stock shocks during long drives or when carrying heavy loads.
