Rancho RS7MT 4″ Front Lift Shocks for 2011-2018 Chevy Silverado 2500HD

Part Number: RS77380

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, these shocks provide the precision required to manage the increased unsprung weight of larger wheel and tire combinations. Configured specifically for 4-inch front lift applications, they eliminate the aeration and fade common in standard twin-tube shocks during aggressive off-road use or heavy towing. This system ensures your Silverado or Sierra maintains a stable, controlled ride regardless of the terrain.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a lightning-fast response rate to ensure consistent tire-to-road contact.
• Internal Floating Piston: The dedicated oil/gas separator provides zero aeration of the hydraulic fluid to ensure fade-free performance during high-frequency cycling.
• Hardened Nitro-Coated Rod: A durable, corrosion-resistant piston rod provides superior seal protection to ensure long-term service life in harsh environments.
• Application-Specific Valving: Custom-tuned damping profiles provide optimized rebound and compression to ensure a balanced ride on leveled or lifted HD trucks.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically length-tuned to work with an existing 4-inch front lift kit to ensure proper travel and prevent bottoming out.

What is the benefit of a Monotube shock over a Twin-Tube?
Monotube shocks like the RS7MT feature a single cylinder and a floating piston that keeps the oil and nitrogen separate, which prevents foaming (aeration) and allows for much cooler operation under load.

Are these sold as a pair?
Yes, based on the SKU configuration (2xRS77380), this product includes two front shocks for a complete axle installation.
