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..

Still going strong with no problems. I am getting ready to remove my hubs and inspect my brakes before our spring travel and I dont expect any issues . I will naturally have to replace seals and Kodiak hub oil then I will be set for couple more years of trouble free travel. I really enjoy not having to dealing with having to repack the wheel bearings on a yearly basis it was always a pain especially after getting older in life. Thanks
