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

Part Number: RS55128

Summary: The Rancho RS5000X series leverages a cross-tuned twin-tube design to provide a significant upgrade in ride quality and durability for lifted applications. Engineered specifically for vehicles with a 4-inch front lift, these shocks utilize a unique valving system that minimizes aeration and foaming. This ensures a smooth, consistent street performance while maintaining the ruggedness required for light off-road use and heavy-duty utility.

Features

• Progressive Engagement Valving: A custom-tuned compression disk stack provides reduced harshness during initial impacts to ensure a smoother ride over small road imperfections.
• Twin-Tube Gas Pressure Design: The 2.25-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during extended use.
• Nitro-Carburized Piston Rod: A 16mm heavy-duty rod construction provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.
• Polyurethane Bushings: High-density mounting material provides enhanced durability and reduced deflection to ensure precise handling and noise vibration harshness (NVH) control.

Frequently Asked Questions

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55128_n681) includes a pair of two (2) shocks for the front of your vehicle.

Will these shocks provide 4 inches of lift to my GMC Suburban?
No, these shocks do not create lift. They are specifically valved and length-matched to work with vehicles that already have a 4-inch lift kit installed.

What is the benefit of the included shock boots?
The red protective boots shield the nitro-carburized piston rod from road debris, salt, and mud, which helps prevent premature seal failure.
