Trailair Flex Air Pin Box Clearance From Tailgate And Bed Rails Of A 2017 Chevy Silverado 2500

Updated 10/12/2021 | Published 10/11/2021

Question:

Can I use a flex air trail air long tow pin box on a 2017 Chevy 2500 HD 66inch bed with out hitting the tail gate or sides of the bed or should I use a medium hitch. Also I have a 1621 lippet box now.

The Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000lbs # LC369535 has 3" difference from king pin to front bolt row when compared to a standard 1621 pin box so it will be that much closer to your tailgate and sides. This will slightly help with turning clearance and the height difference can be adjusted if your 5th wheel hitch has an adjustable hitch head. I recommend hooking up to your trailer and measuring from the distances you currently have to see if you can accommodate losing 3".
