Rancho RS5000X 1.5″ Lift Shocks for 1973-1990 GMC G-1500

Part Number: RS55120

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade over factory dampening for your GMC G-1500. Engineered for durability and smooth street comfort, these shocks feature a unique valving system that minimizes aeration and foaming. This specific set is configured for vehicles with a 1.5-inch lift, ensuring the piston operates within its optimal range for improved ride quality and stability.

Features

• Progressive Engagement Valving: A custom-tuned shim stack provides a smooth transition between low and high-speed impacts to ensure consistent comfort on varied road surfaces.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and fade to ensure reliable performance during extended driving.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural integrity to ensure long-term durability against debris and harsh environments.
• Glass-Filled Fluoro-Ethyl Band: A specialized internal seal provides a friction-reduced interface between the piston and pressure tube to ensure a quicker response to road irregularities.

Frequently Asked Questions

Will these shocks lift my vehicle 1.5 inches?
No, these shocks do not create lift. They are specifically lengthened and valved to accommodate a vehicle that has already been equipped with a 1.5-inch lift kit.

How does the twin-tube design benefit my daily drive?
The twin-tube design allows for a larger oil capacity and a more compliant valving setup, which results in a smoother, “plush” ride that absorbs small road vibrations more effectively than many high-pressure monotubes.

Are the boots included with the shocks?
Yes, this set includes Rancho’s signature red protective boots to help shield the shock rods from dirt, moisture, and road debris.
