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

Part Number: RS77379

Summary: The Rancho RS7MT Monotube series is engineered for high-performance handling and rapid heat dissipation on the GMC Sierra 3500HD. Designed for vehicles at factory ride height, these shocks feature a high-pressure nitrogen charge that eliminates performance-robbing aeration. This monotube design provides the precise response required for heavy-duty hauling and off-road stability, ensuring your truck maintains composure under demanding loads.

Features

• Monotube Construction: A 1.97-inch (50mm) diameter body provides increased fluid capacity to ensure consistent damping and cooler operating temperatures.
• High-Pressure Nitrogen Charge: The 200 PSI gas charge provides immediate response to surface changes to ensure maximum tire-to-road contact.
• Hardened Nitro-Coated Rod: The heavy-duty piston rod provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• Hydraulic Rebound Stop: An internal plunger provides a controlled cushion at full extension to ensure protection against metal-on-metal bottoming out.

Frequently Asked Questions

Will these shocks lift my GMC Sierra 3500HD?
No, these shocks are configured for a 0-inch lift and are designed to replace factory-length shocks without changing the vehicle’s ride height.

What is the benefit of a monotube design over a twin-tube?
Monotube shocks like the RS7MT offer better heat dissipation and faster reaction times because the single-tube design allows for a larger piston and prevents oil foaming.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77379) includes 2 shocks for the rear of your vehicle.
