Rancho RS5000X 4″ Front Lift Shocks for 2011-2018 GMC Sierra 2500HD

Part Number: RS55380

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade over factory damping for heavy-duty applications. Utilizing a sophisticated twin-tube design, these shocks are specifically configured for GMC Sierra 2500HD/3500HD models with a 4-inch front lift. The Cross-Tuned technology delivers a unique valve transition that reduces harshness while maintaining the durability required for towing and off-road use.

Features

• Progressive Engagement Valving: A custom-tuned compression disk stack provides reduced initial impact harshness to ensure a smoother ride over small road imperfections.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent response by minimizing aeration and foam buildup to ensure fade-free performance during heavy-duty cycles.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural integrity and corrosion resistance to ensure long-term reliability in harsh environments.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and dent resistance to ensure the internal piston remains functional even if the outer shell is damaged.

Frequently Asked Questions

Will these shocks lift my GMC Sierra?
No, these shocks do not create lift. They are specifically lengthened and valved to accommodate a GMC Sierra 2500HD that already has a 4-inch front lift kit installed.

Are these shocks sold as a pair?
Yes, this SKU (2xRS55380_n605) includes a pair of front shocks to cover both the driver and passenger sides.

What is the benefit of the twin-tube design for my truck?
The twin-tube design is highly durable for daily use and off-roading; the outer tube acts as a shield, ensuring that if it is dented by debris, the inner cylinder where the piston travels remains unaffected.
