Rancho RS5000X 4″ Lift Shocks for 1988-2000 GMC K2500 4WD

Part Number: RS55244 / RS55227

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your lifted GMC K2500. Utilizing a sophisticated twin-tube design with Progressive Engagement Valving, these shocks effectively manage the increased unsprung weight of larger tires and 4-inch lift kits. Whether navigating highway commutes or rugged job sites, the RS5000X delivers a smooth, controlled feel that eliminates the harshness often associated with heavy-duty suspension systems.

Features

• Progressive Engagement Valving: Custom-tuned internal compression and rebound circuits provide a soft ride during initial travel to ensure comfort on small bumps and road chatter.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent oil column to ensure reduced aeration and shock fade during heavy cycling.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior scuff resistance and structural integrity to ensure long-term durability in harsh environments.
• Double-Welded Mounts: Reinforced loop-to-loop connections provide extra strength at high-stress points to ensure the shocks withstand off-road articulation.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and extended in length to accommodate a truck that has already been equipped with a 4-inch suspension lift kit.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for daily driving and off-roading; if the outer tube is dented by a rock or debris, the inner cylinder remains protected, allowing the shock to continue functioning.

Are the boots included?
Yes, this set includes Rancho’s signature red protective boots to shield the piston rods from dirt, mud, and road salt.
