Rancho RS7MT 4″ Rear Lift Shocks for 2007-2014 GMC Yukon

Part Number: RS77274

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on vehicles equipped with aftermarket lift kits. Utilizing a sophisticated monotube design, these rear shocks provide the precision and consistency required for both highway stability and demanding off-road excursions. By separating the gas and oil with a floating piston, the RS7MT eliminates aeration to ensure your GMC Yukon maintains a controlled, predictable ride regardless of terrain intensity.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a lightning-fast response rate to ensure consistent damping over washboard surfaces.
• Internal Floating Piston (IFP): The physical barrier between the shock oil and nitrogen gas provides zero aeration to ensure fade-free performance during high-frequency cycling.
• Hardened Nitro-Churuck Shaft: The heavy-duty piston rod provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• Polyurethane Bushings: High-density mounting material provides enhanced durability compared to rubber to ensure a quiet, vibration-free connection to the chassis.

Technical Specifications

Fitment

• 2007-2014 GMC Yukon
• Note: New Body with Rancho Suspension

What’s Included

• Includes 2 Shocks

Why Choose This Product?

• Engineering Advantage: Unlike standard twin-tube shocks, the RS7MT’s monotube architecture allows for a larger piston area and better cooling, making it the superior choice for lifted SUVs.
• Performance Benefit: Drivers will experience a significant reduction in body roll and “float,” resulting in a more planted and confident feel behind the wheel.

Frequently Asked Questions

Will these shocks lift my vehicle 4 inches?
No, these shocks do not create lift. They are specifically valved and length-matched to work with a GMC Yukon that already has a 4-inch rear lift kit installed.

Is the monotube design better for towing?
Yes. The monotube design dissipates heat more efficiently than twin-tube shocks, which helps maintain consistent damping and control when the rear of the vehicle is under heavy loads or towing.

What does the IFP (Internal Floating Piston) do?
The IFP separates the nitrogen gas from the shock oil. This prevents the oil from foaming (aeration), which is the primary cause of shock “fade” during spirited driving or off-road use.
