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

Part Number: RS77380

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 and consistent damping required for leveled or lifted applications. Specifically configured for 4-inch lifts, they eliminate the “mushy” feel often associated with stock-style twin-tube shocks by separating the oil and nitrogen gas for fade-free performance. Whether navigating highway stretches or managing heavy payloads, the RS7MT ensures your Silverado or Sierra 3500HD maintains superior stability and control.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides rapid response times to road inputs to ensure immediate stability and control.
• Internal Dividing Piston: A floating piston separates the gas and oil to provide zero aeration and fade resistance to ensure consistent performance during aggressive driving.
• Hardened Nitro-Carburized Rod: A 14mm piston rod provides extreme durability and corrosion resistance to ensure a long service life in harsh environments.
• Integrated Dust Boot: A protective bellows boot provides a physical barrier against road debris and mud to ensure the internal seals remain free of contaminants.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and length-adjusted to be used on vehicles that already have a 4-inch lift kit installed.

Is the monotube design better than my factory shocks?
Yes. Most factory shocks are twin-tube designs. The RS7MT monotube design offers faster cooling and more precise valving, which is critical for the added weight and geometry of a lifted 3500HD.

Do I need to purchase boots separately?
No, these shocks come equipped with protective boots to shield the piston rod from road salt, rocks, and debris.
