Rancho RS7MT 4″ Front Lift Shocks for 2011-2018 GMC Sierra 3500HD

Part Number: RS77380

Summary: The Rancho RS7MT Monotube series is engineered to provide high-performance handling and rapid heat dissipation for heavy-duty applications. Specifically configured for 4-inch lifted GMC Sierra 3500HD models, these shocks utilize a high-pressure nitrogen gas charge to eliminate aeration and foaming. The monotube design ensures a precise, consistent damping response whether you are navigating highway miles or demanding off-road terrain.

Features

• Monotube Design: A 2-inch diameter body with a high-pressure nitrogen charge provides rapid heat dissipation to ensure consistent performance during aggressive driving.
• Internal Floating Piston (IFP): The large bore oil chamber separated by a floating piston provides a physical barrier between gas and oil to ensure zero aeration and instantaneous damping response.
• Hardened Nitro-Carburized Rod: A 14mm piston rod with specialized coating provides superior corrosion resistance and durability to ensure long-term seal integrity in harsh environments.
• Sealing System: An integrated dirt wiper and multi-lip seal provide a clean environment for internal components to ensure leak-free operation under heavy loads.

Frequently Asked Questions

Will these shocks lift my GMC Sierra 3500HD 4 inches?
No, these shocks do not create lift. They are specifically valved and length-tuned to work with vehicles that have already had a 4-inch lift kit installed.

What is the benefit of the Monotube design over a standard shock?
The monotube design features a single wall that allows for faster cooling and uses a floating piston to separate the gas and oil, preventing the oil from foaming during rapid cycling.

Do these shocks include the required mounting hardware?
Yes, these shocks include the necessary bushings and hardware required for a standard installation on the GMC Sierra 3500HD.
