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

Part Number: RS55001 / RS55112

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your GMC Suburban. Utilizing a sophisticated gas-pressurized twin-tube design, these shocks are specifically configured for vehicles with 2.5 to 4 inches of lift. By implementing Rancho’s Crossed-Tuned technology, this set balances off-road ruggedness with smooth street performance, effectively eliminating the harshness often associated with lifted applications.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition between damping stages to ensure consistent comfort on uneven terrain.
• Gas-Pressurized Twin-Tube: Low-pressure nitrogen gas charge provides reduced aeration and foaming to ensure reliable performance during sustained cycling.
• Cross-Tuned Technology: Specific internal valving calibration provides a balanced damping profile to ensure stability during both high-speed highway driving and low-speed crawling.
• Protective Boot Included: High-quality polyvinyl accordion boots provide a physical barrier against road debris and moisture to ensure the longevity of the polished piston rod.

Frequently Asked Questions

Will these shocks lift my GMC Suburban?
No, these shocks do not create lift. They are specifically sized and valved to work with a vehicle that already has a 2.5 to 4-inch suspension lift installed.

What is the benefit of the RS5000X over a standard hydraulic shock?
The RS5000X is gas-pressurized, which prevents the oil from foaming (aeration) during rapid movement, ensuring the shock doesn’t lose its damping effectiveness on rough roads.

Do I need to purchase boots separately?
No, this kit includes four red protective boots to protect the shock rods from dirt, mud, and road salt.
