4400# axles are 6-bolt

I've never ever seen a 4400 LB axle on an RV because it has the same 10" hubs/brakes as a 3500 axle. 12" drums on a 6,000 axle.

Provided the manufacturer mounted the axles properly Dexter axle ID is stamped in the rear facing middle of the tube. Take a small piece of sand paper and a flashlight to see better. I can't speak for any brand other than Dexter.

there are a LARGE number of trailer with the 4400lb axles. yes, they have 10" drums, 6 lugs and most of them have a 5200lb tube, the spindle is also unique to the 4400lb.

Turns out I have 5200 lb axels. Did not realize I just had to look at a sticker on the axel. Trailer is a 2018 Outback 325BH. Looking at MoRyde 4000 series or Lippert Road Armor suspensions as a fall project. Still trying to decide which. Morryde is the most expensive by almost double but gets great reviews.
