Rancho RS5000X 4″ Rear Lift Shocks for 1992-1999 GMC Suburban 1500 2WD

Part Number: RS55190

Summary: The Rancho RS5000X series features an innovative cross-tuned twin-tube design that delivers a significant upgrade over factory damping for lifted applications. Engineered to handle the increased leverage of a 4-inch lift, these shocks utilize a unique valving system that reduces harshness during initial impacts. This ensures a smooth, controlled ride for your GMC Suburban 1500, whether navigating city streets or maintaining stability under load.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides increased control during high-velocity movements to ensure consistent handling on uneven terrain.
• Twin-Tube Gas Pressurized Design: The 2.25-inch reserve tube provides extra oil capacity to ensure cooler operating temperatures and reliable damping performance.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm diameter rod provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.
• Polyurethane Bushings: High-density pivot points provide improved durability and reduced deflection to ensure precise suspension geometry.

Frequently Asked Questions

Will these shocks lift my GMC Suburban by 4 inches?
No, these shocks do not create lift. They are specifically valved and sized to function correctly with vehicles that have already been modified with a 4-inch suspension lift kit.

What is the benefit of the RS5000X gas pressurization?
The low-pressure nitrogen gas charge minimizes the mixing of oil and air (foaming), which ensures consistent damping force even during frequent suspension cycling.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55190) includes a pair of two (2) shocks for the rear of your vehicle.
