Rancho RS7MT 4″ Rear Lift Shocks for 2011-2018 Chevy Silverado 3500HD

Part Number: RS77381

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 shocks provide the precision response required for the Chevy Silverado and GMC Sierra 3500HD when configured for a 4-inch rear lift. By separating the gas and oil with a floating piston, the RS7MT eliminates oil aeration to ensure consistent damping performance during heavy towing or off-road excursions.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a lightning-fast damping response to ensure stability on unpredictable terrain.
• Internal Floating Piston (IFP): The physical partition between gas and oil provides zero aeration to ensure fade-free performance under high-cycle conditions.
• Hardened Nitro-Carburized Rod: The heavy-duty piston rod provides superior scuff and corrosion resistance to ensure long-term seal integrity.
• Application-Specific Valving: Custom-tuned shim stacks provide precise control for heavy-duty chassis to ensure a balanced ride between payload and empty beds.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and sized for vehicles that already have a 4-inch rear lift kit installed.

How many shocks come in this package?
This SKU includes 2 shocks (one pair) for the rear of your vehicle.

What is the benefit of a Monotube over a Twin-Tube shock?
Monotube shocks react faster to road inputs and dissipate heat more efficiently than twin-tube shocks, preventing the “fading” feeling during heavy use.
