Rancho RS7MT 1-2.5″ Front Lift Shocks for 2001-2010 GMC Sierra 2500HD

Part Number: RS77370

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on heavy-duty applications. Utilizing a sophisticated monotube design, these shocks provide the precision and consistent damping required to manage the increased unsprung weight of larger wheel and tire combinations. Configured for 1-2.5 inches of front lift, they effectively eliminate the “mushy” feel of factory dampers while ensuring zero aeration during aggressive off-road use.

Features

• Monotube Construction: A high-pressure nitrogen gas charge and 1.97-inch (50mm) body provide rapid response times to ensure maximum control on unpredictable terrain.
• Internal Floating Piston (IFP): The physical barrier between the nitrogen gas and premium all-weather fluid provides consistent damping by preventing aeration to ensure fade-free performance.
• Hardened Nitro-Churized Rod: The 14mm heavy-duty piston rod provides superior scuff and corrosion resistance to ensure long-term seal integrity.
• Sealing System: An integrated dirt wiper and multi-lip seal provide a clean rod surface and fluid retention to ensure durability in harsh environments.

Frequently Asked Questions

Will these shocks lift my GMC Sierra?
No, these shocks do not create lift. They are specifically valved and length-tuned to be used on vehicles already equipped with a 1-2.5 inch front leveling kit or lift system.

What is the benefit of the RS7MT monotube over a standard shock?
The monotube design features a larger piston and a high-pressure gas charge that prevents oil foaming (aeration), resulting in more consistent performance and faster cooling during heavy use.

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