Will Curt Flex Air 5th Wheel Pin Box Work with Demco Hijacker Autoslide 5th Wheel Hitch

Question

Question:

Would like to replace my Lippert 1621 pinbox with a Lippert FlexAir TrailAir# 328492 pinbox. I currently have a Demco #8551000 autoslide in my truck. Is the FlexAir compatible with my Demco Autoslide. Thanks

Yes, the Curt Flex Air 5th Wheel Pin Box part # LC328492 is compatible with the Demco Hijacker Autoslide 5th Wheel Hitches but you'd need new capture plates for the hitch, the Demco Autoslide Capture Plates for Trailair Rota-Flex Pin Boxes part # DM6171. These allow a much better fit between the pin box and fifth wheel hitch for better performance.

Because it's lighter, less expensive, has fewer moving parts and is mechanically less complicated I'd recommend going with the Gen-Y #325-GH-8040 shock absorbing pin box versus a Trailair Flex Air like part #LC328492. The Trailair features a…
