Rancho RS5000X 4″ Lift Shocks for 2011-2018 GMC Sierra 2500HD

Part Number: RS55380

Summary: The Rancho RS5000X series leverages a patented progressive engagement valving system to deliver a refined ride for your GMC Sierra 2500HD. Engineered specifically for vehicles with a 4-inch lift, these shocks utilize a large 2.25-inch body to increase fluid capacity and maintain cooler operating temperatures. The twin-tube gas-pressurized design provides exceptional durability and dent resistance, ensuring consistent performance during heavy-duty hauling or off-road excursions.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides restricted flow at low speeds and increased flow as velocity rises to ensure a smooth street ride without sacrificing off-road control.
• 2.25-inch Twin-Tube Body: An oversized shock housing provides increased oil capacity to ensure reduced internal temperatures and consistent damping under heavy loads.
• Nitrogen Gas Charging: Pressurized gas displacement provides a barrier against oil aeration and foaming to ensure fade-free performance during rapid suspension cycling.
• Protective Polyvinyl Boot: A high-durability accordion boot provides a physical shield for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

Will these shocks lift my GMC Sierra?
No, these shocks do not create lift. They are specifically length-tuned to function correctly on vehicles already equipped with a 4-inch suspension lift.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable for work trucks; if the outer body is dented by a rock or debris, the inner cylinder remains functional, allowing the shock to continue operating.

Does this kit include all four shocks?
Yes, based on the SKU configuration, this package includes a full set of four shocks for the front and rear of the vehicle.
