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

Part Number: 2xRS55128_2xRS55190_n681

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to enhance the ride quality of your lifted GMC Suburban. Designed specifically for vehicles with 4 inches of suspension lift, these shocks manage the increased unsprung weight of larger tire packages while maintaining daily-driver comfort. The twin-tube gas-pressurized design provides a durable, dent-resistant outer body that ensures consistent performance during light off-road use or highway cruising.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a soft ride during initial travel to ensure smooth street comfort.
• Twin-Tube Gas Pressure: The low-pressure nitrogen charge reduces aeration and foaming to ensure consistent damping under high-cycle conditions.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term durability against rock chips and corrosion.
• Polyurethane Bushings: High-density mounting material reduces NVH (Noise, Vibration, and Harshness) to ensure a quiet and controlled cabin environment.

Frequently Asked Questions

Will these shocks lift my GMC Suburban?
No, these shocks do not create lift. They are specifically valved and extended to accommodate a GMC Suburban that already has a 4-inch suspension lift installed.

Are these shocks sold as a complete set?
Yes, this SKU includes a full set of four shocks (two front and two rear) specifically matched for your 2WD Suburban.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for daily use; if the outer tube is dented by road debris, the inner workings of the shock remain protected and functional.
