Rancho RS7MT 1-2.5″ Front Lift Shocks for 2002-2006 Chevy Avalanche 1500

Part Number: RS77371

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on leveled or lifted trucks. Featuring a sophisticated monotube design with a nitrogen gas charge, these shocks provide the precise damping required to maintain tire-to-road contact during aggressive off-road maneuvers. Specifically configured for 1-2.5 inches of front lift, they effectively eliminate aeration and shock fade to ensure consistent performance across varied terrain.

Features

• Monotube Construction: A high-pressure nitrogen gas-charged 2-inch body provides rapid heat dissipation to ensure consistent damping performance during high-frequency cycling.
• Internal Floating Piston (IFP): The large-bore dividing piston separates the gas and oil chambers to provide zero aeration and instantaneous response to surface changes.
• Hardened Nitro-Coated Rod: A 14mm piston rod with specialized coating provides superior corrosion resistance and seal longevity to ensure durability in harsh environments.
• OE-Style Mounts: The application-specific mounting hardware provides a direct-fit installation to ensure a secure connection to the factory chassis points.

Why Choose This Product?

• Engineering Advantage: The RS7MT utilizes a high-pressure gas charge and specialized internal valving that reacts faster than traditional twin-tube shocks, making it ideal for larger tire and wheel combinations.
• Performance Benefit: Drivers will experience reduced body roll and improved steering feedback, providing a more controlled “connected-to-the-road” feel both on and off the pavement.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically valved and lengthened to be compatible with vehicles already equipped with 1-2.5 inches of front suspension lift.

What is the benefit of the Monotube design?
The monotube design allows for a larger piston and better heat dissipation compared to twin-tube shocks, preventing the oil from foaming (aeration) during heavy use.

Do these work with the Z55 Electronic Suspension?
No, these shocks are designed to work with the ZW7 Nivomat suspension and are explicitly not compatible with the Z55 Electronic/Autoride suspension systems.
