Rancho RS5000X 5-6″ Lift Shocks for 2011-2018 Chevy Silverado 2500HD

Part Number: RS55382 / RS55383

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted heavy-duty trucks. Engineered specifically for the 2011-2018 Chevy Silverado and GMC Sierra 2500HD/3500HD, these shocks handle the increased unsprung mass of larger wheel and tire combinations. The gas-pressurized twin-tube construction provides excellent durability and dent resistance while maintaining smooth street comfort during daily transit.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between low and high-speed impacts to ensure controlled handling over varied terrain.
• 2.25-inch Twin-Tube Body: A larger fluid capacity provides increased cooling efficiency to ensure consistent damping performance under heavy loads.
• Nitrogen Gas Pressure: 150 PSI gas charge provides immediate response and minimizes aeration to ensure fade-free performance.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically sized and valved to work on vehicles that have already been modified with a 5-6″ lift kit.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for daily driving and off-road use; if the outer body is dented by a rock, the inner cylinder is protected, allowing the shock to continue functioning.

Do I need to purchase boots separately?
No, this kit includes the signature Rancho red protective boots to safeguard the shock rods from debris.
