How to Measure to Determine Correct Replacement 5th Wheel Pin Box
Question:
HOW DO I MEASURE MY PINBOX
asked by: Paul
Expert Reply:
A replacement pin box can be confirmed by cross-referencing the brand and part number that appear on its safety sticker (usually on its left side) or by taking measurements of its dimensions and mounting holes.
The Lippert Trailair pin box # LC328492 that you referenced matches up to and directly bolts on in place of a Lippert 1621 pin box. Part # LC155943 fits in place of a Lippert 1116 pin box.
The linked articles show both how to cross-reference a new pin box based on your OEM part and to measure your pin box.
