Rancho RS5000X 4″ Rear Lift Shocks for 2001-2010 GMC Sierra 2500HD

Part Number: RS55297

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to deliver a refined ride for your heavy-duty truck. Engineered specifically for vehicles with a 4-inch rear lift, these shocks feature a cross-tuned twin-tube design that provides exceptional durability and dent resistance during off-road use. By minimizing aeration and shock fade through a gas-pressurized charge, they ensure consistent damping performance and smooth street comfort for daily driving and hauling.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping circuits to ensure a smooth ride over small bumps while maintaining control during large impacts.
• Twin-Tube Gas Pressure: A nitrogen-charged 2.25-inch body provides increased fluid capacity to ensure lower operating temperatures and reduced fade during extended use.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod diameter provides increased structural rigidity to ensure long-term seal integrity in harsh environments.
• Protective Boot: An included polyvinyl accordion boot provides a physical barrier against debris to ensure the chrome rod remains free of pits and scratches.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened and valved for vehicles that have already had a 4-inch lift kit installed.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable; if the outer body is dented by a rock or debris, the inner working tube remains unaffected, allowing the shock to continue functioning properly.

Are these sold as a pair?
Yes, based on the SKU configuration, this product includes two (2) rear shocks.
