Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1987-1991 Chevy V30, V3500 4WD

Part Number: RS55134

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your heavy-duty Chevy or GMC truck. Utilizing a sophisticated gas-pressurized twin-tube design, these shocks are specifically configured for 2.5 to 4 inches of rear lift, ensuring proper suspension travel and control. The RS5000X focuses on delivering smooth street comfort while maintaining the ruggedness required for off-road environments and work-site demands.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between damping forces to ensure consistent ride quality over varying terrain.
• Gas Pressurization: High-pressure nitrogen gas charge provides reduced aeration and foaming to ensure fade-free performance during heavy hauling.
• Double-Welded Mounts: Reinforced loop-style mounts provide maximum structural integrity to ensure the shock withstands high-stress suspension cycling.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal life against debris and corrosion.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically sized and valved to work with vehicles that have already been modified with a 2.5 to 4-inch rear lift kit.

What is the benefit of the RS5000X gas charge?
The nitrogen gas charge keeps the internal hydraulic oil under pressure, which prevents the oil from foaming (aeration) during rapid movement, maintaining consistent damping performance.

Are these sold as a pair?
Yes, this specific SKU (2xRS55134) includes a pair of two (2) shocks for the rear of your vehicle.
