Given your 3 inch diameter axle beam, you have a 5200, 6000 or 7000 lb rated axle, which is compatible with a 12x2 inch brake assembly.

A 12x2 brake assembly would use a standard 5 bolt brake mounting flange. For a 3 inch diameter axle beam, I'd recommend using # 4-44-1 for 3 inch axles.

You'll want to have a professional welder who's experienced in trailer work install these. If they aren't installed so they're perfectly straight and concentric, you'll have no end of trouble.

Answer 1

I can see how that would throw you off. The Brake Mounting Flange for 3" Round Axle part #4-44-1 is designed to mount onto the spindle just behind the seals it doesn't sit all the way inboard so it's not around the entire axle. I've…

According to Dexter Axle, the attachment bolts for a 5-bolt brake assembly should be torqued to 30-50 foot/lbs. If you don't have a torque wrench handy, if you tighten the bolts until the lock washers flatten out, you'll be pretty darn close…

Answer 5

Because the 8-14.5 tire that you've got sits on a 14.5" wheel, so you wouldn't be able to switch tire sizes with anything that we have available without also switching to a new wheel as well. If you've got a 6 on 5-1/2" bolt…

Answer 6

It sounds like you have an older style trailer axle with the short spindles. You will need a new Spindle #TRU44FR to mount on your axle as the short hubs are now obsolete. This will allow you to use the what is now standard length spindle dimensions.…

Answer 9

The inner diameters of the LM67048 and 15123 both are the same (1.250 inches). That means that a hub with either bearing in the outer bearing would fit your spindle. The part #AKHD-655-6-EZ-K would fit your axle.

Answer 10

You will need to get the other bearing number from inside your current hubs before we can pick you out replacement hubs. Most likely the outer bearing you pulled is a LM67048 and the inner you have is a 25580 which would mean that the #8-201-5UC3…

Answer 12

The measurements of the Brake Mounting Flange for a 3 inch Round Axle, part #4-44-1, are correct, in that the inner diameter of the flange is 2-3/4 inches. This is because the flange will be mounted to the spindle, not the axle. You will need to…
