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

Part Number: RS55380

Summary: The Rancho RS5000X series provides a sophisticated twin-tube gas pressurized solution for lifted heavy-duty trucks. Engineered to handle the increased unsprung weight of 4-inch lift configurations, these shocks utilize CrossTune Technology to balance highway comfort with off-road control. This complete set ensures your Silverado or Sierra 3500HD maintains consistent damping performance while mitigating the harshness often associated with lifted suspension geometries.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between damping forces to ensure a comfortable ride on varied terrain.
• CrossTune Technology: A unique internal valve design provides a precise balance between control and comfort to ensure stability during towing or hauling.
• Gas Pressurized Design: High-pressure nitrogen gas charge provides reduced aeration and foaming to ensure consistent performance during spirited driving.
• 16mm Nitro-Carburized Rod: Heavy-duty piston rod construction provides increased structural rigidity to ensure long-term durability against debris and pitting.

Frequently Asked Questions

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

What is the benefit of the twin-tube design?
The twin-tube design provides an outer chamber that acts as a reservoir, making the shock more resistant to external damage (dents) without affecting the internal piston movement.

Are the boots required for installation?
While the shocks will function without them, the included red boots protect the nitro-carburized rods from rock chips and salt, extending the life of the oil seals.
