Rancho RS5000X 1.5″ Rear Lift Shocks for 1987 GMC R1500 2WD

Part Number: RS55118

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to optimize ride quality on the 1987 GMC R1500. By integrating a unique progressive engagement valving system, these shocks provide a smooth street feel while maintaining the durability required for light off-road use. Engineered to accommodate a 1.5-inch rear lift, they ensure your vehicle remains composed under various load conditions without sacrificing comfort.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping stages to ensure a balanced ride across varying terrains.
• Nitrogen Gas Pressurization: A high-pressure gas charge minimizes oil aeration and foaming to provide consistent damping performance during extended use.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior scuff resistance and structural integrity to ensure long-term seal life.
• Twin-Tube Body: A 2.25-inch outer tube provides increased oil capacity and dent resistance to ensure the internal piston remains functional even if the outer shell is damaged.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and sized to work with a vehicle that has already been equipped with 1.5 inches of rear lift components.

What is the benefit of the RS5000X over the original RS5000?
The RS5000X features a larger 2.25-inch body and cross-tuned valving, providing better heat dissipation and a more refined ride than the original series.

Are dust boots included with these shocks?
Yes, these shocks include Rancho’s signature red protective boots to shield the piston rod from debris and contaminants.
