From what I could find out, the Big Tex 22GN tandem axle trailers use 10,000 pound axles. However, this is the brand new ones so I highly recommend double checking this with Big Tex if you are unsure. They will need the VIN for your trailer, so have that near by. If they confirm this information or if you are already sure you have 10,000 pound axles, it does narrow the search down to 2 options.

First is the # 10-51. This will have an inner diameter of 2.875" and an outer diameter of 3.880". This is typical for Dexter 9K and 10K axles

Second is the # 10-56. This will have an inner diameter of 3.125" and an outer diameter of 4.5". This one is typically on AL-KO 12K axles, Dexter 10K, 12K, and 15K axles, and Hayes 10K to 12K axles.

If you are unsure of which axle you have, this will be another thing Big Tex can confirm. There may still be a sticker/label on the axle tube, but these wear off over time and may not be legible anymore.
