Rancho RS7MT 4″ Rear Lift Shocks for 1999-2007 GMC Sierra 1500 4WD

Part Number: RS77269

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation. Utilizing a sophisticated monotube design, these rear shocks provide the precision response required for lifted GMC Sierra and Hummer H2 applications. By separating the gas and oil with a floating piston, the RS7MT eliminates aeration and shock fade during aggressive off-road use while maintaining a controlled, firm ride on the street.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides immediate damping response to ensure consistent control over washboard terrain.
• Internal Floating Piston (IFP): The dedicated oil-to-gas separator provides zero aeration and foaming to ensure fade-free performance during high-duty cycles.
• Hardened Nitro-Carburized Rod: A 14mm piston rod provides superior scuff resistance and durability to ensure long-term seal integrity in harsh environments.
• Application-Specific Valving: Custom-tuned shim stacks provide the ideal balance of compression and rebound to ensure stability for vehicles with 4 inches of rear lift.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and sized to accommodate vehicles that have already been modified with a 4-inch rear lift kit.

What is the benefit of a Monotube design?
A monotube design uses a single cylinder and a floating piston to keep the oil and nitrogen gas separate, which prevents the oil from foaming (aeration) and ensures the shock stays cool and consistent under stress.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77269) includes a pair of two (2) rear shocks.
