Rancho RS5000X 4″ Front Lift Shocks for 2011-2018 Chevy Silverado 3500HD

Part Number: RS55380

Summary: The Rancho RS5000X series leverages advanced CrossTune technology to provide a significant upgrade over factory damping for lifted heavy-duty trucks. Specifically configured for 4-inch front lift applications, these twin-tube gas-pressurized shocks utilize a progressive engagement valving system to maintain smooth street comfort while resisting bottoming out during off-road use. By minimizing aeration and foaming, the RS5000X ensures consistent performance and durability for the Chevy Silverado and GMC Sierra 3500HD under demanding loads.

Features

• CrossTune Technology: A unique progressive valving system provides a custom-tuned compression and rebound profile to ensure balanced handling on both highway and trail.
• Twin-Tube Gas Pressurization: A 150-PSI nitrogen gas charge provides reduced aeration and foaming to ensure consistent damping performance during rapid cycling.
• Nitro-Carburized Piston Rod: A heavy-duty reinforced rod construction provides increased scuff resistance and protection against the elements to ensure long-term seal integrity.
• Protective Boot: An included high-quality accordion bellows provides a physical barrier against road debris and mud to ensure the longevity of the shock shaft and oil seals.

Frequently Asked Questions

Will these shocks lift my truck 4 inches?
No, these shocks do not create lift. They are extended-length dampers designed to work with a truck that has already been equipped with a 4-inch suspension lift kit.

What is the benefit of the Twin-Tube design on the RS5000X?
The twin-tube design is highly durable for work trucks; the outer tube can take a dent from road debris without affecting the inner cylinder or the movement of the piston.

Are these sold as a pair?
Yes, this SKU (2xRS55380) includes a pair of two (2) shocks for the front of your vehicle.
