When it’s time to replace a scored or worn-out drum, this Dexter hub-and-drum assembly makes the job simple. It’s built for 5,200-lb rated axles and works with both electric and hydraulic drum brakes. The 12" x 2" drum surface gives the brake shoes plenty of area to grip for steady, confident braking.
Getting the right fit matters most when you’re rebuilding an axle. This assembly is matched with the inner bearing 25580 (1.75" ID), outer bearing LM67048 (1.25" ID), and grease seal RG06-070 (2.25" ID × 3.376" OD). The races, seal, grease cap, wheel bolts, and nuts all come with it, so you’ve got the core hardware ready for installation without hunting for loose parts.
Dexter’s iron hub and drum take on real-world loads without backing down. The 6 on 5-1/2" bolt circle with 1/2"-20 wheel studs gives you a solid, standard connection to common trailer wheels from 14-1/2" up to 16-1/2". The sturdy build holds up mile after mile, whether you’re refitting an older trailer or keeping a spare hub ready for roadside use.
Because it’s a complete hub-and-drum assembly, you can swap it in when your brakes still have life but the drum surface is grooved or damaged. That means less downtime and a smoother ride once you’re back on the road. It’s a straightforward, proven setup designed for lasting performance in everyday towing.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

The final result worked quite well. After learning the cause of the self-adjusting brakes overtightening from a different source but the etrailer staff should have recognized the issue I loaded my 2500 pound sports car on my trailer for a round trip of about 1500 miles and was very satisfied with the brake performance.
