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

Part Number: RS55380

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to enhance the ride quality of your leveled or lifted heavy-duty truck. Specifically configured for a 4-inch lift, these shocks balance rugged off-road durability with smooth highway manners by minimizing harshness over small bumps. The gas-pressurized architecture provides the necessary damping force to handle the increased unsprung weight of larger wheel and tire combinations on the Silverado and Sierra HD platforms.

Features

• Cross-Tuned Technology: A unique valve calibration system provides a progressive engagement of the valving to ensure a smooth ride during daily driving while maintaining control during off-road excursions.
• Gas Pressurization: High-pressure nitrogen gas charging provides reduced aeration and foaming to ensure consistent damping performance under heavy workloads.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased fluid capacity and dent resistance to ensure long-term reliability in harsh environments.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior scuff resistance and corrosion protection to ensure seal longevity.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened to accommodate the travel requirements of a truck already equipped with a 4-inch lift kit.

What is the benefit of the twin-tube design for my Silverado?
The twin-tube design is highly durable for daily use; the outer tube acts as a shield, so if a rock dents the body, the inner cylinder (where the piston moves) remains functional.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55380_n94) includes a pair of two (2) shocks for the front of your vehicle.
