Recommended Pin Box Replacement Lippert 1621 Pin Box On Alpine Trailer

Question:

The rp61422 says that it is compatible with the Lippert 1621 that I have on my Alpine. The 1621 is rated at 19,000 lbs but the rp61422 is only rated at 16,000 lbs. Why the discrepancy? Isnt there a 19,000 lb version? Thanks.

The 5th Airborne Premium 5th Wheel Air Ride King Pin, part # RP61422, is designed as a replacement for the Lippert 1621 you currently have on your Alpine. It is rated with a 16,000 lb weight capacity.

If more weight capacity is needed, then I recommend part # LC158778. This replacement king pin has a 21,000 lb weight capacity.

We do not offer a 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret replacement pin box with a higher capacity than 16,000 lbs that replaces your 1621 pin box

All three of these replacements are designed to be replacements for your 1621 pin box you currently have.
