The Lippert Components 807711 Flex Air Pin Box delivers superior towing comfort and stability for fifth wheel trailers with up to 21,000 lbs gross weight capacity. This advanced king pin coupler features Air Ride™ technology that absorbs road shock and vibration before it reaches your trailer, providing a smoother, quieter ride.

Key Features:

• 21,000 lb gross weight capacity for heavy-duty fifth wheel applications
• Air Ride™ technology with integrated air bag suspension system
• Rota-Flex® pivoting head for enhanced articulation and reduced bind
• Oil shock absorber combined with rubberized compound for maximum vibration dampening

The combination of air bag suspension and oil shock technology significantly reduces the jarring impact from road irregularities, potholes, and rough pavement. The Rota-Flex® pivoting head allows for improved articulation during turns and uneven terrain, reducing stress on both the truck bed and trailer frame. This premium pin box upgrade enhances ride quality, reduces frame fatigue, and protects cargo from excessive movement during travel.
