This hub assembly is designed to handle serious weight. It’s built for 15K heavy-duty Dexter axles and carries a 7,500-lb capacity per hub. The sturdy iron construction gives it the strength needed for demanding use while keeping things straightforward when you need reliability under load.
Greasing bearings can be messy and time-consuming. This hub uses an oil bath system, which keeps the bearings lubricated and makes inspections easy. Just check the oil level through the clear cap (sold separately), top off when needed, and you’re ready to roll without the hassle of frequent repacking.
When you’re swapping out a worn or damaged hub, fitment accuracy matters. This assembly matches up as a direct replacement for Dexter’s heavy-duty hub-and-drum assembly (008-401-72). That means less measuring, no guesswork, and confidence that it’ll seat cleanly on compatible spindles.
With an 8 on 275mm bolt pattern and 22mm wheel bolt diameter, this hub fits standard heavy-duty wheel setups. The 5/8" studs give solid clamping force for large wheels so you can torque the lugs down tight and know the wheel’s secure mile after mile.
Getting bearing races seated just right can slow down a rebuild. This hub comes with both inner (3920) and outer (28622) races already pressed in from the factory. You just add the bearings (28682 inner and 3984 outer, sold separately), oil seal, oil cap, and lug nuts, and you’re ready to mount it up without any extra tools.
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"

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the Dexter Oil Bath trailer hub assembly with the eight on 275 millimeter bolt pattern and the 22 millimeter studs for your heavy duty 15,000 pound axle. Now this trailer hub assembly is designed to fit the heavy duty 15,000 pound axles with drum brakes. This will work as a direct replacement for the heavy duty hub and drum assembly, which we do sell separately. That goes by a part number of 008-401-72. And I did want to pop up an insert just to show you there's what that hub and drum assembly looks like and this part is just for the hub portion of it.
Now the bearing races are included and they are pre-installed in the hub, but now the bearings, the oil seal, the oil cap and the lug nuts are not included. Those you would have to buy separately. As we mentioned, it's an Oil Bath design, so it allows for easy maintenance. Basically it lets you check your lubricant level without having to disassemble the hub like on a grease hub. Basically when you have the oil cap on here, it's a clear see through oil cap, so you can check the lubrication by looking through that clear oil cap.
This is a sturdy iron construction. The hub is made in the USA. Again application, this is gonna fit 15,000 pound axles with drum brakes. The bolt pattern we mentioned is gonna be eight on 275 millimeters. The stud size 22 millimeters and the weight capacity on this one hub is 6,000 pounds.
But that's gonna do it for a look at this Dexter Oil Bath trailer hub assembly with the eight on 275 millimeter bolt pattern and the 22 millimeter studs.

Product works well
wrong part....hub is not for 10000 lb axle...looks like a 12000 lb axle
It does not fit my trailer wheel. So now I must pay freight charges to send it back and drive 3 hours one way to find the correct replacement part so I can get my Hot Shot trailer back in service and try to make a paycheck
All their products are of good quality and the customer service is even better. Definitely will be buying from them again in the future.

The trailer hub was the correct one. It was received in very well pachaged box in a speedy manor, delivered the day promised. Will do business again. Thanks......
IT WAS THE PERFECT FIT, SHIPPING WAS QUICK AND CUSTOMER SERVICE WAS GREAT.
All went well with the shipping and installation. I would recommend etrailer for parts.
Do you have bearing seals suited for salt water emersion? our biggest problem is salt water getting into the hub and destroying the bearings. we use these on our oversized boat trailer.
etrailer Troy is great he helped me get the parts i needed and was really concerned about helping. in this day and time thats rare to find someone so helpful. i will recommend Troy and etrailer to everyone. Bobby
Ships right away and parts are correct. We buy from all the time and highly recommend them to anyone I know!!
On time, and as ordered. Thanks!
you do not disclose that this is the high profile version of this hub. That being said I needed a low profile version and am down for at least an additional week now waiting on the correct hub from another source.
Fit exactly how everything should. Very helpful when I called with a question got me back up and running.
Fast and reliable.
Etrailer always treats you right. They even have a REAL knowledgeable person just a phone call away. Fast, great prices, and helpful; that's a winning combo!
