When you’re hauling serious weight, you need a hub-and-drum setup that’s made for it. This Dexter assembly is built for 5,200-lb to 7,000-lb axles and uses a 12" diameter x 2" wide drum that works with both electric and hydraulic brakes. The rugged design delivers consistent braking performance and durability for demanding loads.
Getting everything lined up can take time, but this hub comes with the races and wheel bolts already in place. That means fewer steps during install and a solid starting point for your bearings, seals, and grease cap (sold separately). Once it’s mounted, you’re ready to finish out your brake assembly and hit the road.
This hub-and-drum assembly is designed for oil bath lubrication, giving you a system that runs cooler and lasts longer. Just fill it with standard gear oil—90 weight or 80W-90 both work well—and you’ve got a setup that reduces friction and cuts down on wear. It’s an easy way to keep your hubs in good shape trip after trip.
Keeping your wheels tight and true is simple with its 8 on 6-1/2" bolt pattern and 9/16" studs. The hub is lug-centric, meaning the wheel centers on the lug nuts for a precise, balanced fit. That dependable connection gives you smooth rotation and steady braking every time.
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'll take a look at this 12 inch Dexter oil bath trailer hub and drum assembly with the 8 on 6 1/2 inch bolt pattern, has the 9/16 diameter wheel studs and it's for a 5,200 pound to 7,000 pound Dexter axle. Now this trailer hub and drum assembly is what'll provide the surface area for your brake shoes to grip when your brakes are activated. It's compatible with both 12 inch electric or hydraulic drum brakes. It is a sturdy iron construction. Dimension on this, the diameter, inside to inside, is 12 inches.
The width on it right here is gonna be 2 inches wide. And again, the application, this is for 5,200 pound to 7,000 pound Dexter axles. Does have the bolt pattern of 8 on 6 1/2 inches that accepts the wheel size of 16 inch up to 17 1/2 inches. We mentioned the wheel stud diameter on this assembly is 9/16 of an inch, and the weight capacity is 3,500 pounds per assembly. So when this one's used with one on the other side of the axle, it'll meet up to the 7,000 pound axle rating.
Now this part does include the bearing races. They are already pre-installed in the hub from the factory. Now, the bearings, the seals, the caps, and all the lug nuts, they are not included. Those items we do sell separately on our website. But that should do it for the review on the 12 inch Dexter oil bath trailer hub and drum assembly with the 8 on 6 1/2 inch bolt pattern, the 9/16 diameter wheel studs for the 5,200 pound to 7,000 pound Dexter axles..

Very fast shipping and installation went very well! I will definetly recommend and be a returning customer.
Easy to install
Original parts were wrong. Talked with Tara and she fixed the problem. Thank you for taking care of the issue.
Service and delivery was spot on staff that I talked to were great thanks it won’t be the last time I order
We received only three of the four packages that were supposed to have arrived… not sure where the fourth is, but we’re in a real pickle without it.!
Quick Communication and getting issues resolved quicker than we request
Arrived quickly. Even though item was heavy it was packaged well with no damage. First time buying from this site and was very pleased.
The product was just what I ordered but the packaging was inadequate for the weight of the hub. The package came apart and was retaped by ups. Since the package was damaged, several prices were missing and one of the bearings was damaged. I was able to get by with purchasing the missing and damaged items locally.
great product for the price. have had no problems with them at all
Ordered yesterday and had it the next morning. very fast shipping and excellent product and service
It was easy finding the right hub for the trailer. Everything was correct and made the job easy to complete.
Need to ship in better packaging. Boxes came in with holes. Parts were missing.
Replacement parts were sent out but the job is now delayed waiting on the parts.
Hub was exactly as described. Perfect fit and replacement.
Great Price!!!!!
One hub arrived damaged, poor packaging. Also these are single units Not pairs. Be prepared to buy per wheel as needed.
Good price and free shipping. Thank You
The hub and bearings came quickly, fit perfectly, and have run as they should. I'm a happy customer.
Product was an exact replacement part and fit perfectly. Quality, service, and price were all excellent. Only took 3 businee days to receive my order. Had my 53 ft car hauler up and running just a few hours after parts arrived. Thank you etrailer
Im only giving a level of three star because I really only needed the spindle but it was not in stock, and the time to restock was far to long, so I paid much more and guess I have a spare hub now. Delivery was quick and the product is good. Thank You
The break parts are like original. When we got it back together we got our trailer DOT certified.Life can go on.
I received my parts on time and in good order. I ordered two left hand brake assemblies, and two right hand assemblies. Unfortunately, four right hand units were delivered. To the companies credit, they refunded me for two of the units. Also the knock off oil bath 12 inch Dexter brake drum hub assemblies, which were very good quality, did not have the oil drain hole drilled in the side of the hub like the originals. This made it slightly more difficult to fill them with oil and they also will be more difficult to drain them, add oil and refill. I will be tempted to purchase the original Dexters in the future.
everything fit great
Best choice I have ever made. My fifth wheeler tires never get higher than 90degrees F on the roads from the good old Texas. Equivalent to 3K miles round trip to my beautiful twin cities MN.
The prosses of ordering parts from etrailer was very Stright forward and prompt updates on my item were quite helpful.
Perfect fit. I bought these because I wanted to change my horse trailer from No. 2 wheel bearing grease to No. 00 semi fluid grease. It’s the best characteristics of both grease and oil hubs without the negatives if you ask me. Well I needed a vented hub so the oil bath hubs. A tube and a half later of Schaeffer’s 274 Moly EP synthetic NLGI#00 grease and all bearings packed, hubs half full of grease and everything torqued to spec and I was done. There really is no better place for trailer parts than etrailer. Best prices and fast shipping.
Great product I installed them and put 8000 miles on my trailer after. No problems as of yet really impressed with the overall quality. THANKS
