Rancho RS7MT 1-2.5″ Front Lift Shocks for 2011-2022 Chevy Silverado 2500HD

Part Number: RS77378

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on heavy-duty trucks. Utilizing a sophisticated monotube design with a variable-rate disc valving system, these shocks provide the precision needed to manage the increased unsprung mass of larger tires and leveled stances. Configured for 1-2.5 inches of front lift, they eliminate the “mushy” feel of factory dampers by providing a firmer, more controlled response during both on-road cornering and off-road articulation.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a faster damping response to ensure consistent tire contact on uneven terrain.
• Internal Floating Piston (IFP): The large-bore dividing piston separates the gas and oil to provide zero aeration and fade-free performance during high-frequency cycling.
• Hardened Nitro-Carb Rod: A 14mm piston rod with specialized coating provides superior corrosion resistance and seal longevity to ensure durability in harsh environments.
• Variable-Rate Disc Valving: Application-specific tuning provides a precise transition between soft and firm damping to ensure optimal control for heavy-duty towing and hauling.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured with the correct travel and length to accommodate vehicles already equipped with 1 to 2.5 inches of front lift.

What is the benefit of a monotube over a twin-tube shock?
Monotube shocks like the RS7MT feature a single-wall design that dissipates heat more efficiently and uses an IFP to prevent the oil from foaming, ensuring consistent performance under heavy use.

Are these shocks compatible with factory torsion keys?
Yes, these shocks are ideal for trucks that have been leveled using aftermarket torsion keys or factory adjustments up to 2.5 inches, provided no spacers are used.
