Rancho RS5000X 4″ Rear Lift Shocks for 1988-2000 GMC K2500 4WD

Part Number: RS55227

Summary: The Rancho RS5000X Series gas-pressurized shocks are engineered to provide a significant upgrade in durability and ride quality for your GMC K2500. Utilizing a sophisticated twin-tube design with a larger 2.25-inch body, these shocks offer increased oil capacity to maintain cool operating temperatures on rough terrain. Specifically configured for vehicles with a 4-inch rear lift, they provide the necessary travel and damping control to eliminate the harshness often associated with lifted suspension geometries.

Features

• Crossed Landscape Valve System: A progressive engagement valving system provides custom-tuned damping to ensure smooth street comfort and controlled off-road handling.
• Gas Pressurization: High-pressure nitrogen gas charging provides a reduction in aeration and foaming to ensure consistent performance during rapid suspension cycling.
• 2.25-inch Twin-Tube Body: An oversized shock body provides increased fluid capacity to ensure lower internal temperatures and fade-free operation.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

Frequently Asked Questions

Will these shocks lift my GMC K2500?
No, these shocks do not create lift. They are specifically sized and valved to function on vehicles already equipped with a 4-inch rear lift kit.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is exceptionally durable; even if the outer body is dented by a rock or debris, the inner working cylinder remains protected, allowing the shock to continue functioning.

Are these sold as a pair?
Yes, this specific SKU (2xRS55227) includes two rear shocks to complete the installation for one axle.
