Rancho RS7MT 0″ Front Lift Shocks for 2011-2020 GMC Sierra 3500HD

Part Number: RS77377

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on heavy-duty trucks. Utilizing a sophisticated monotube design, these front shocks provide the precision and responsiveness needed to manage the heavy front-end GAWR of the GMC Sierra 3500HD. By separating the gas and oil with a floating piston, the RS7MT eliminates oil foaming and aeration, ensuring consistent damping performance whether you are navigating highway expansion joints or maintaining control on corrugated work sites.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides immediate damping response to ensure precise vehicle control during sudden maneuvers.
• Internal Floating Piston (IFP): The physical barrier between nitrogen and hydraulic fluid provides zero aeration to ensure fade-free performance under high-duty cycles.
• Hardened Nitro-Coated Rod: A 14mm heavy-duty piston rod provides superior scuff resistance to ensure long-term seal integrity in harsh environments.
• Integrated Sealing System: A multi-lip wiper seal provides a clean rod surface to ensure the internal oil remains free of contaminants.

Frequently Asked Questions

Will these shocks lift my GMC Sierra 3500HD?
No, these shocks are configured for 0-inch lift and are designed to replace the factory-length dampers. They do not provide lift height themselves.

What is the benefit of a monotube shock over the factory twin-tube?
The monotube design features a larger single piston and a high-pressure gas charge, which reacts faster to road imperfections and dissipates heat much more efficiently than a traditional twin-tube shock.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77377_n643) includes two front shocks to complete the front axle of your vehicle.
