Rancho RS5000X 4″ Lift Shocks for 2011-2018 Chevy Silverado 2500HD

Part Number: 2xRS55380_2xRS55381_n94

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your heavy-duty truck. Specifically tuned for vehicles with a 4-inch lift, these shocks utilize a cross-tuned twin-tube design to soak up harsh road impacts and off-road chatter. This complete set ensures your Silverado or Sierra maintains a controlled, comfortable stance whether you are commuting or hauling heavy loads.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between low and high-speed impacts to ensure consistent comfort on varied terrain.
• Twin-Tube Gas Pressure Design: The 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures and reduced fade during heavy-duty use.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior corrosion resistance and structural integrity to ensure long-term durability in harsh environments.
• Polyurethane Bushings: High-density mounting points provide enhanced pivot articulation to ensure reduced noise, vibration, and harshness (NVH) transfer to the chassis.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and extended in length to function correctly on a vehicle that already has a 4-inch suspension lift installed.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design features an outer reserve tube that protects the inner working cylinder from rock chips or dents, ensuring the shock remains functional even in demanding off-road conditions.

Is the hardware included for installation?
Yes, this kit includes all necessary bushings and hardware required to replace your factory shocks on the 2011-2018 Silverado/Sierra 2500HD and 3500HD platforms.
