Question:
2019 keystone Montana High Country LCI 4358151 What flex air pin box do I need to replace the Lippert pin box I have on there now? The current one has a long jaw with 9 holes on each side but I’m not being shown the flex air model by strainer that matches the hole pattern. Please help. Thanks

Hello Anthony. The LCI pin box 4358151 uses the 1116 bolt pattern, and there is not a Flex Air pin box that fits this bolt pattern. What you can use is the Trailair Air Ride 5th Wheel Pin Box # LC155943 which is the air ride equivalent for your 1116 pin box.
