Rancho RS5000X 4″ Front Lift Shocks for 2011-2018 GMC Sierra 3500HD

Part Number: RS55380

Summary: The Rancho RS5000X series leverages a patented progressive engagement valving system to significantly reduce harshness during initial impacts. Designed for the GMC Sierra 3500HD, these twin-tube gas-pressurized shocks provide a smooth, comfortable street ride while maintaining the durability required for off-road excursions. Configured for 4-inch front lift applications, they offer the necessary travel and damping control to manage the heavy-duty requirements of your truck’s front end.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping stages to ensure a smooth ride over small bumps and road chatter.
• Gas Pressurized Twin-Tube Design: High-pressure nitrogen gas charge reduces aeration and foaming to ensure consistent performance during spirited driving or heavy hauling.
• 16mm Nitro-Carburized Piston Rod: The heavy-duty hardened rod construction provides superior scuff resistance and corrosion protection to ensure a long service life in harsh environments.
• Self-Lubricating Seal: A specialized seal retainment system reduces friction and heat to ensure the shock operates reliably across extreme temperature ranges.

Frequently Asked Questions

Will these shocks lift my GMC Sierra 3500HD?
No, these shocks do not create lift. They are specifically lengthened and valved to work with a vehicle that already has a 4-inch front lift kit installed.

How does the RS5000X differ from a standard shock?
The RS5000X features a unique “Progressive Engagement Valving” system which allows the shock to react instantly to road speed and terrain changes, unlike standard shocks which have a fixed damping rate.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55380_n641) includes two front shocks to complete the front axle of your vehicle.
