Rancho RS7MT 1-2.5″ Front Lift Shocks for 1999-2004 GMC Sierra 2500 4WD

Part Number: RS77370

Summary: The Rancho RS7MT Monotube series is engineered to provide high-performance handling and rapid heat dissipation for your GMC Sierra 2500. Designed specifically for vehicles with 1-2.5 inches of front lift, these shocks utilize a high-pressure nitrogen gas charge to eliminate oil aeration and foaming. The result is a precise, fade-free damping experience that remains consistent whether you are navigating highway expansion joints or demanding off-road trails.

Features

• Monotube Design: A high-pressure nitrogen gas charge provides rapid response times and consistent damping to ensure zero aeration during aggressive driving.
• Internal Floating Piston: The physical separation of gas and oil provides a larger surface area for heat dissipation to ensure fade-free performance under heavy loads.
• Hardened Nitro-Coated Rod: A 14mm piston rod provides superior corrosion resistance and structural integrity to ensure long-term durability in harsh environments.
• Application-Specific Valving: Custom-tuned internal shim stacks provide precise control for the Sierra’s front suspension geometry to ensure a balanced, stable ride.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured and valved for trucks that already have 1 to 2.5 inches of front suspension lift installed.

What is the benefit of a Monotube over a Twin-Tube shock?
The RS7MT Monotube design features a single cylinder and a floating piston that separates the gas and oil, allowing the shock to run cooler and react faster to road inputs compared to a twin-tube design.

Do I need special tools for the S51 upper mount?
The S51 stem mount is designed to fit into the factory mounting location using standard hand tools; no modifications to the chassis are required.
