IS #84 AXLE CONSIDER ED A 1inch AXLE

A true 1 inch spindle is a BT8 spindle, like # TRU94FR. The next closest one would be the BTR spindle which is commonly referred to as a 1-1/16 inch spindle, like # TRU44FR and is more common than the BT8. Both of these are typically used with 2,000 lb axles.
A #84 spindle, like # TRU24FR or # TRU47FR is bigger and is used for 3,500 lb axles. Common sizes for these are 2-3/8 inch round axle, 3 inch round axle, and 2 inch square axle.
I have linked a helpful page that shows the different spindle selections that we offer and what size axles that they fit. But the easiest way to make sure that you get the correct spindle is to go by either your axle capacity or the bearing numbers. If you let me know what either of those are, I can make a recommendation for you.
