Rancho RS7MT 0″ Lift Shocks for 2014-2019 GMC Sierra 1500 Old Body

Part Number: RS77830

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on both the GMC Sierra 1500 and Yukon. Utilizing a sophisticated monotube design, these shocks provide the precise damping required to maintain vehicle stability during aggressive driving or heavy hauling. This set is specifically configured for vehicles at factory ride height (0″ lift), offering a significant upgrade over stock components by eliminating oil aeration and ensuring consistent performance under demanding conditions.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a quicker damping response to ensure precise control on uneven terrain.
• Internal Floating Piston (IFP): The large bore piston separates the nitrogen gas from the shock oil to provide fade-free performance and ensure consistent damping during rapid cycling.
• Hardened Nitro-Carburized Rod: The 14mm piston rod provides superior scuff and corrosion resistance to ensure a long service life in harsh environments.
• Sealing System: A specialized high-temperature multi-lip seal provides a redundant oil barrier to ensure leak-free operation under extreme thermal loads.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks are configured for 0″ of lift and are designed to replace factory-length shocks while improving ride quality.

Do these work with Magnetic Ride Control?
No, these are designed for vehicles with standard suspension and explicitly exclude models equipped with Z95 Magnetic Ride Control.

What is the benefit of the RS7MT monotube over a standard shock?
The monotube design uses a single-wall tube and a floating piston to keep gas and oil separate, which prevents foaming (aeration) and allows the shock to work harder for longer periods without losing damping force.
