Rancho RS5000X 5-6″ Front Lift Shocks for 2011-2018 GMC Sierra 3500HD

Part Number: RS55382

Summary: The Rancho RS5000X series leverages a patented progressive engagement valving system to enhance the handling and ride quality of your heavy-duty truck. Designed for vehicles with 5 to 6 inches of front lift, these twin-tube shocks provide exceptional durability and dent resistance for demanding environments. By minimizing fluid aeration and harshness, these shocks deliver a smooth street ride while maintaining the control necessary for off-road excursions and towing tasks.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition of damping force to ensure a smooth ride over small bumps while maintaining control during large impacts.
• Gas Pressurized Twin-Tube Design: A 150 PSI nitrogen gas charge provides a reduction in aeration and foaming to ensure consistent performance during sustained suspension cycling.
• Robust Shock Body: A 2.25-inch diameter reserve tube provides increased oil capacity for cooler operation to ensure long-term durability under heavy loads.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a shield for the piston rod to ensure the oil seal remains free from debris and contaminants.

Frequently Asked Questions

Will these shocks lift my GMC Sierra 3500HD?

What is the benefit of the twin-tube design on this model?
The twin-tube design is highly durable for work trucks; the outer tube can take a dent from road debris without affecting the inner cylinder or the movement of the piston.

Does this include both front shocks?
Yes, this SKU (2xRS55382_n640) includes a pair of two (2) front shocks.
