Rancho RS7MT 0″ Rear Lift Shocks for 2011-2020 GMC Sierra 2500HD

Part Number: RS77379

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on both the GMC Sierra 2500HD and 3500HD. Featuring a sophisticated monotube design, these rear shocks provide the precision response needed to eliminate body roll and maintain stability under heavy loads. Configured for 0-inch lift heights, they serve as a premium upgrade for stock-height heavy-duty trucks seeking superior damping control over standard twin-tube alternatives.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides immediate damping response to ensure consistent control on washboard roads.
• Hardened Nitro-Carburized Rod: The heavy-duty piston rod provides increased durability and corrosion resistance to ensure a long service life in harsh environments.
• Internal Floating Piston: The physical separation of gas and oil provides aeration-free performance to ensure fade-free damping during towing or hauling.
• Large Bore Diameter: An increased piston surface area provides more precise valving sensitivity to ensure a smooth ride on uneven pavement.

Frequently Asked Questions

Will these shocks lift my GMC Sierra?
No, these shocks do not create lift. They are configured for vehicles with 0-inches of rear lift and are designed to replace factory-length shocks.

What is the benefit of the RS7MT monotube over a standard shock?
The monotube design dissipates heat much faster than twin-tube shocks and uses an internal floating piston to prevent oil foaming, which maintains consistent performance during heavy use.

Are these sold as a pair or individually?
Based on the SKU 2xRS77379, this specific package includes a pair (2) of rear shocks.
