Rancho RS7MT 1-2.5″ Front Lift Shocks for 2011-2022 Chevy Silverado 3500HD

Part Number: RS77378

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on heavy-duty GM trucks. Utilizing a sophisticated monotube design with a nitrogen gas charge, these shocks provide the precise damping required to manage the unsprung weight of larger wheel and tire combinations. Specifically configured for 1-2.5 inches of front lift, they eliminate the “mushy” feel of factory dampers while ensuring consistent performance during aggressive off-road use or heavy hauling.

Features

• Monotube Construction: A high-pressure 46mm bore provides rapid response times to road inputs to ensure maximum tire-to-ground contact.
• Internal Floating Piston (IFP): The physical barrier between the nitrogen gas and hydraulic fluid prevents aeration and foaming to ensure fade-free performance in high-heat cycles.
• Hardened Nitro-Coated Rod: A 14mm heavy-duty piston rod resists pitting and corrosion to ensure long-term seal integrity and durability.
• Application-Specific Valving: Custom-tuned damping rates provide improved body roll control to ensure a stable and predictable ride for heavy-duty 3500HD applications.

Why Choose This Product?

• Engineering Advantage: The RS7MT utilizes a high-pressure nitrogen charge and a large 46mm bore, which reacts faster than traditional twin-tube shocks to maintain stability under load.
• Performance Benefit: Drivers will experience a significant reduction in vehicle sway and “nose-dive” during braking, resulting in a more confident driving experience both on and off the pavement.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to accommodate vehicles already equipped with 1″ to 2.5″ of front lift.

What is the benefit of the Monotube design?
The monotube design separates the gas and oil, which prevents the fluid from foaming (aeration). This allows the shock to work harder for longer periods without losing its damping effectiveness.

Can I use these with shock spacers?
No, as per the fitment notes, these shocks are not for use with aftermarket shock spacers or relocation brackets, as this may exceed the designed travel limits of the damper.
