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

Part Number: RS77377 / RS77379

Summary: The Rancho RS7MT series is engineered specifically for high-performance handling and heat dissipation on heavy-duty trucks. Utilizing a sophisticated monotube design, these shocks provide the rapid response necessary to manage the unsprung weight of the GMC Sierra 2500HD and 3500HD. This complete set is configured for vehicles at factory ride height (0″ lift), offering a significant upgrade in stability and control over stock twin-tube units.

Features

• Monotube Construction: A high-pressure nitrogen gas charge separated from the oil provides consistent damping to ensure zero aeration during aggressive driving.
• Internal Floating Piston (IFP): The large bore piston design provides a larger surface area for valving sensitivity to ensure precise control on varied terrain.
• Hardened Nitro-Churized Rod: The heavy-duty piston rod construction provides superior scuff and corrosion resistance to ensure long-term seal integrity.
• Application-Specific Valving: Custom-tuned shim stacks provide optimized damping for heavy-duty towing to ensure reduced body roll and improved stability.

Frequently Asked Questions

Will these shocks lift my GMC Sierra?
No, these shocks are designed to work with vehicles at the factory ride height (0″ of lift) and do not provide any lift themselves.

What is the benefit of the RS7MT over a standard shock?
The RS7MT is a monotube shock, which dissipates heat faster than twin-tube shocks, preventing performance fade during heavy towing or off-road use.

Is this a complete set for my truck?
Yes, this SKU includes all four shocks (two front and two rear) required for a full vehicle replacement.
