Rancho RS7MT 5-6″ Lift Shocks for 2005-2007 Chevy Silverado 1500HD 4WD

Part Number: RS77055

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on vehicles equipped with 5 to 6 inches of suspension lift. Utilizing a sophisticated monotube design, these shocks provide the precise damping required to manage larger tire masses and increased center of gravity. This system is specifically tuned to eliminate aeration and maintain consistent control during aggressive off-road maneuvers or heavy-duty hauling.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides rapid piston response to ensure consistent damping over varied terrain.
• Internal Floating Piston (IFP): The dedicated oil/gas separator provides zero aeration of the hydraulic fluid to ensure fade-free performance during high-frequency cycling.
• Hardened Nitro-Carburized Rod: The 14mm heavy-duty piston rod provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• Application-Specific Valving: Custom-tuned shim stacks provide optimized compression and rebound damping to ensure a balanced ride for lifted Chevy and GMC trucks.

Why Choose This Product?

• Engineering Advantage: The RS7MT’s monotube architecture offers superior cooling surface area compared to twin-tube designs, preventing oil thinning during heavy work cycles.
• Performance Benefit: Drivers will experience a significant reduction in body roll and “float,” resulting in a planted, confident feel on both highway and trail.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and extended to accommodate vehicles already equipped with a 5″ to 6″ suspension lift kit.

How does the monotube design help with off-roading?
The monotube design uses a high-pressure gas charge to keep the oil and air separate. This prevents the oil from foaming (aeration), which ensures your shocks don’t lose damping power when the trail gets rough.

Do these fit models with Magnetic Ride Control?
No, these shocks are designed for standard suspension configurations and are not compatible with Electronic Suspension (Z55) or Magnetic Ride Control (Z95) systems.
