Rancho RS7MT 1-2.5″ Front Lift Shocks for 2011-2020 GMC Sierra 2500HD

Part Number: RS77378

Summary: The Rancho RS7MT series is engineered for high-performance handling and precise control on the GMC Sierra 2500HD. These monotube shocks are specifically configured for 1-2.5 inches of front lift, providing a leveled stance and improved clearance. By utilizing a high-pressure nitrogen gas charge and a floating dividing piston, these shocks eliminate aeration and shock fade during intense driving conditions. Whether navigating highway stretches or demanding work sites, the RS7MT ensures a consistent, responsive ride for heavy-duty applications.

Features

• Monotube Design: A high-pressure 46mm bore provides rapid heat dissipation to ensure consistent damping performance under heavy loads.
• Internal Floating Piston: The physical separation of nitrogen gas and hydraulic fluid provides zero aeration to ensure immediate response to road inputs.
• Nitro-Carburized Piston Rod: A specialized surface treatment provides superior corrosion resistance to ensure long-term durability in harsh environments.
• Application-Specific Valving: Custom-tuned internal shim stacks provide precise control for heavy-duty trucks to ensure reduced body roll and improved stability.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured for vehicles that have already been leveled or lifted 1″ to 2.5″ via torsion key adjustments or other suspension modifications.

What is the benefit of a Monotube over a Twin-Tube shock?
Monotube shocks like the RS7MT react faster to road changes and dissipate heat more efficiently, making them ideal for heavy-duty trucks and off-road use where performance consistency is vital.

Can I use these with my factory shock spacers?
No, these shocks are not for use with aftermarket shock spacers or relocation brackets as per the manufacturer’s fitment notes.
