Rancho RS5000X 4″ Rear Lift Shocks for 1988-2000 GMC C2500 2WD

Part Number: RS55190

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 rear lift, these shocks utilize a unique valving system that minimizes harshness over small bumps while maintaining firm control during heavy suspension cycling. This makes them an ideal solution for GMC owners seeking a balance between rugged off-road durability and smooth street comfort.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide increased control during high-velocity impacts to ensure a stable ride on uneven terrain.
• Gas Pressurized Twin-Tube: High-pressure nitrogen charging provides reduced aeration and foaming to ensure consistent damping performance under heavy loads.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides superior scuff resistance and structural integrity to ensure long-term seal life.
• Protective Boot Included: A durable polyvinyl accordion boot provides a physical barrier against road debris and moisture to ensure the chrome rod remains free of pitting.

Frequently Asked Questions

Will these shocks lift my GMC C2500?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles that have already been equipped with a 4-inch rear lift kit.

What is the benefit of the gas charging in the RS5000X?
The nitrogen gas charge puts pressure on the internal hydraulic fluid, which prevents the fluid from foaming (aeration) during rapid movement, ensuring your shocks don’t lose damping power during spirited driving.

Are these shocks sold as a pair?
Yes, based on the SKU configuration, this product includes 2 shocks for the rear of your vehicle.
