Rancho RS5000X 4.5″ Rear Lift Shocks for 2014-2018 GMC Sierra 1500

Part Number: RS55297

Summary: The Rancho RS5000X series leverages a patented progressive engagement valving system to deliver a refined ride for lifted GMC Sierra 1500 and Hummer H2 applications. Engineered for vehicles with 4.5 inches of rear lift, these twin-tube gas-pressurized shocks provide exceptional durability and dent resistance for off-road environments. By minimizing aeration and foaming, the RS5000X ensures consistent damping performance and smooth street comfort during daily transit.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping stages to ensure controlled handling over varied terrain.
• Twin-Tube Gas Pressure: A 150-PSI nitrogen gas charge provides a consistent pressure barrier to ensure reduced aeration and shock fade.
• 16mm Nitro-Carburized Rod: The heavy-duty piston rod construction provides increased tensile strength and corrosion resistance to ensure long-term seal integrity.
• Protective Boot: The included polyvinyl accordion boot provides a physical barrier against debris to ensure the longevity of the polished piston rod.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 4.5-inch rear lift kit to ensure the piston operates within its optimal travel range.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55297) includes 2 shocks for a complete rear axle installation.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-road use; if the outer tube is dented by a rock or debris, the inner working tube remains unaffected, ensuring you aren’t stranded on the trail.
