Rancho RS7MT 0″ Rear Lift Shocks for 1973-1986 GMC C3500 2WD

Part Number: RS77118

Summary: The Rancho RS7MT series is engineered to provide precise handling and rapid heat dissipation for your 1973-1986 GMC C3500. Utilizing a high-pressure monotube design, these rear shocks offer a significant performance upgrade over traditional twin-tube units by eliminating aeration during aggressive driving. Configured for 0-inch lift heights, they serve as a premium OE-length replacement that enhances stability and control for both street and light-duty hauling applications.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a consistent, fade-free damping response to ensure precise vehicle control.
• Internal Floating Piston (IFP): The physical separation of gas and oil provides zero aeration to ensure consistent performance under high-frequency cycling.
• Hardened Nitro-Steel Piston Rod: A 14mm heavy-duty rod provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• OE-Style Mounts: Durable polyurethane bushings provide a direct-fit interface to ensure reduced NVH (Noise, Vibration, and Harshness).

Technical Specifications

Fitment

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured for vehicles with 0 inches of rear lift height.

What is the benefit of a monotube over a twin-tube shock?
Monotube shocks dissipate heat faster and prevent fluid foaming (aeration), which provides more consistent damping during heavy use.

Are boots included with these shocks?
Yes, Rancho RS7MT shocks typically include protective dust boots to shield the piston rod from debris.
