Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1988-2000 GMC K2500 4WD

Part Number: RS55227

Summary: The Rancho RS5000X series utilizes an innovative Cross Tuning system to provide a significant upgrade in ride quality for your GMC K2500. Designed as a high-durability twin-tube solution, these shocks feature a specialized valving system that minimizes harshness during initial impacts. This ensures consistent street comfort while maintaining the ruggedness required for off-road environments and heavy-duty use.

Features

• Cross-Tuned Technology: A unique valve base system provides increased fluid flow and control to ensure smooth transition between varying terrain types.
• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide improved handling to ensure stability during towing or hauling.
• Gas Pressurized Twin-Tube: Nitrogen gas charging provides reduced aeration and foaming to ensure consistent damping performance under heavy loads.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior corrosion resistance to ensure a long service life in harsh environments.
