Air Ride Pin Box for a 2010 Heartland Cyclone 5th Wheel Trailer with Lippert 1621HD Pin Box

Question:

I am considering installing a trailair suspension pin box on my 2010 heartland cyclone fifthwheel. The trouble i am having is that i cannot find anywhere reference to the existing Pin that is currently on the rig. The sticker on the current pinbox says lippert part number 183760 but i cannot find reference to that anywhere online. Do you have any idea what product this would cross reference to? Thanks!

I spoke with my contact at Lippert and we identified the pin box on your 5th wheel trailer as a 1621HD. For just an air ride pin box you can use # 5AB-E1621-610 rated for 21,000 pounds. For an air ride pin box and Sidewinder combo rated for 16,000 pounds use # RP61422. Sidewinders are used on trucks with beds shorter than 6 feet.

The Trailair pin boxes fit the 1621 pin box but are not a fit for the 1621HD pin boxes.
