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

Part Number: RS55383

Summary: The Rancho RS5000X Series is engineered to deliver a significant upgrade in ride quality and durability for heavy-duty trucks. Utilizing a sophisticated twin-tube design with a unique Progressive Engagement Valving system, these shocks provide a smooth street ride while maintaining control under load. Specifically configured for 5-6 inches of rear lift, they ensure your lifted Silverado or Sierra maintains optimal suspension travel and stability on and off the road.

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 aggressive movements.
• Gas Pressurized Twin-Tube: Nitrogen gas charging reduces aeration and foaming to ensure consistent performance during heavy towing or long-distance hauling.
• Large Shock Body: A 2.25-inch diameter reserve tube provides increased fluid capacity to ensure lower operating temperatures and reduced fade.
• Nitro-Carburized Piston Rod: Heavy-duty 16mm rod construction provides superior corrosion resistance and strength to ensure long-term durability in harsh environments.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are designed with the correct extended and compressed lengths to work on trucks that already have a 5-6 inch rear lift kit installed.

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

Are these shocks sold as a pair?
Yes, based on the SKU configuration, this package includes 2 rear shocks to complete the rear axle of your vehicle.
