Does 5th Airborne part # 5AB-E1621-610 Replace Lippert 1621 Pin Box

Question:
Is the 5AB-E1621-610 21,000 lb and is it extended pin box. My current pin box is a Lippert 1621 HD. Also does this pin box cause a clunk noise when pulling away from a stop. I had one on a previous fifth wheel Cross Roads, Cruiser and the clunk seemed to stop now that I have a solid pin box. Thanks

The 5th Airborne # 5AB-E1621-610 that you referenced is an exact replacement for your Lippert 1621 and would have the same amount of extension. The 1621 is considered a "long" or extended pin box.
As long as the air bag of this pin box is inflated properly there would be no clunking as you pull away from stops. This will help smooth the ride out quite a bit actually.
