Rancho RS7MT 4″ Front Lift Shocks for 2011-2018 GMC Sierra 2500HD/3500HD
Part Number: RS77380
Summary: The Rancho RS7MT series is engineered specifically for high-performance handling on leveled or lifted heavy-duty trucks. Utilizing a sophisticated monotube design, these shocks provide the rapid damping response necessary to manage the unsprung weight of larger wheel and tire combinations. Configured for 4-inch lift applications, they eliminate aeration and shock fade during demanding towing or off-road cycles, ensuring your GMC Sierra maintains composed vehicle dynamics regardless of terrain.
Features
- Monotube Construction: A high-pressure nitrogen gas charge separates the oil and gas to provide instantaneous damping response and zero aeration.
- Hardened Nitro-Coated Rod: The heavy-duty piston rod surface provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
- Application-Specific Valving: Internal shim stacks are tuned to the GMC HD chassis weights to provide improved body roll control and stability.
- Internal Floating Piston (IFP): The moving divider piston isolates the high-pressure gas from the oil to ensure consistent performance during rapid cycling.

Frequently Asked Questions
Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically sized and valved to function with a truck that already has a 4-inch front lift kit installed.
What is the benefit of a Monotube design?
The monotube design allows for a larger piston and better heat dissipation, which prevents the shock from becoming “soft” or losing damping power during heavy use.
Are these sold as a pair?
Yes, this specific SKU (2xRS77380_n605) includes a pair of two (2) front shocks.
