Rancho RS5000X 0-2″ Rear Lift Shocks for 1981-1986 Chevy K10 4WD

Part Number: RS55118

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to enhance the ride quality of your Chevy K10. Designed for vehicles with 0-2 inches of rear lift, these twin-tube gas pressurized shocks provide consistent damping and increased durability for both daily driving and off-road excursions. The larger 2.25-inch body diameter increases fluid capacity, ensuring cooler operation and reliable performance under varying load conditions.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a smooth transition between damping circuits to ensure controlled handling on unpredictable terrain.
• Twin-Tube Gas Pressurized Design: The 150 PSI nitrogen gas charge minimizes aeration and foaming to provide consistent damping force during rapid suspension cycling.
• Protective Boot: A heavy-duty red polyvinyl accordion boot protects the 16mm nitro-carburized piston rod from debris to ensure long-term seal integrity.
• Double-Welded Mounts: Reinforced loop-style end mounts provide superior structural rigidity to ensure the shocks withstand the stresses of 4WD applications.

Frequently Asked Questions

Will these shocks lift my Chevy K10?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with 0-2 inches of rear lift to ensure the piston operates within the correct travel range.

What is the benefit of the RS5000X gas charge?
The 150 PSI nitrogen charge puts pressure on the hydraulic fluid, which prevents the oil from foaming (aeration). This ensures the shock maintains its damping effectiveness even during heavy off-road use.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55118_n80) includes 2 rear shocks for a complete axle installation.
