Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Dexter Axle Trailer Hubs and Drums - Hub with Integrated Drum - 8-219-13UC3 Review

Today were going to review part number 8-219-13UC3. This is the Dexter Trailer Hub and Drum Assembly with the 8 on 6-1/2-inch bolt pattern for 9/16 studs. This trailer Hub and Drum Assembly will include the eight 9/16 cone seat lug nuts. It will include the inner bearing, part number 25580, the outer bearing part number 14125A, the grease cap and the 10-36 grease seal. Now the bearing races will also be included but they will already be preinstalled, as you can see, the outer races right here and the inner races already in there. All of our Hub and Drum assemblies when we ship out will have the races already pressed into the assembly.

Now this application will fit most 5200 to 7000-lb Dexter axles. It has a drum dimension of 12-inch diameter by 2-inch wide. The bolt pattern is 8 lug 6-1/2 inch pattern. The stud size is 9/16. Now the capacity on this assembly is 3500 lbs so when this one is used with one on the other side of the axle it will give you maximum capacity of 7000 lbs.

I do want to give you the few dimensions on here. The bolt pattern which will be 8 lugs 6-1/2 inches on a bolt pattern that has an even number of lugs which in this case would be 8, the easiest way is usually to measure from the center, pick any lug or wheel stud and from the center of that stud to the center of the stud directly across from it. In this case this is pretty high so its going to be hard to get an actual--it is 6-1/2 but its hard to get a good--the other way to get a good measurement is just measure from the center of this stud to the one right next to it, either direction. And its 2-1/2 inches. So basically that would tell you that this bolt pattern is an 8 lug 6-1/2 inch bolt pattern.

The other measurement is the drum dimension which would be 12 inches in diameter and that would measure the inside of the drum which is 12 inches and then the width would be 2 inches. So this Hub and Drum assembly will work with a brake assembly that is 12-inch by 2-inch wide. And that should do it for our review on part number 8-219-13UC3.

I ordered Dexter backing plate assembly and drum. Great prices! The drum came with races, bearings and grease seal. Everyone else that I checked with, races, bearings and the were extra and at higher price! I received all the items when expected. I would definitely recommend etrailer to anyone looking for great prices and customer service. Thank you etrailer 225574


Wow! it’s already a year?. So far so good. No problems with any of the parts I ordered..

I bought these to use on a fairly heavy (about 12k #, loaded) 5th wheel. These were bought to replace ones previously purchased w/ 1/2" lugs. I didn't realize there was a difference until they were already installed. Now everything is working beautifully, except I'm now in the middle of replacing the chinese-made wheel bearings that came with the replacements from Etrailer, the reason for 3 stars, vs. 5. Not only is the origin questionable, but the bearings and cups were shipped loose in a bag with the rest of the hardware (lug nuts, etc.) Precision bearings must be individually wrapped, boxed, and never touched directly by human hands, to prevent corrosion, and contamination which lead to early failures. Sorry, but these things are only good for low-speeds, and short distances, such as farm equipment. 351016


The hubs and drums are working well after a season of camping, which didnt see more than a couple hundred miles of travel.

Everything looks good. I purchased this hub assy a a spare for my 50ft Featherlight and thankfully have not had to use it 642904

Product arrived damaged. The bearings and grease caps are damaged. Retailer posted a credit due to the problem. Great company a fast reply on products. 638277

Looks like an exact replacement hub for dexter 7k axle lost a brake shoe on a new 42 foot 2019 forest river fifth wheel, overheated the bearings and seal, this has the same bearings as the original, yes, bearings are from china but so are the original hubs and bearings from dexter, I bought 4 of these a few years ago to update our previous fifth wheel a 32 foot nuwa ran them for over 8k miles with no problem 589121

Your team member was very helpful!! I had tried 2 other companies who just shot me down your guy went the extra mile to get me the right hub!!! Thanks!!! 550941

Worked like a charm. 545226

- 8-219-13UC3

Product was shipped quickly and very well packed , absolutely no box damage for such a heavy item. The hubs look well made and came with all the hardware. Bearings are made in china but what isn't these days my advice is to purchase a bearing grease packing cone so you insure your bearings are fully packed . Everything fit perfectly . 464461


I couldnt be more satisfied with my purchase I have logged over 10000 miles on my rig since I installed my new brakes & drums . just rotated my wheels and inspected my bearings, they look great!

I recently borrowed a trailer from a friend of mine and it had to have been infested with grease worms. Needless to say, burnt up a bearing and spit the hub off before I made it to load. I found the parts I needed on this website, but had to purchase seals and dust caps I didn't need along with a kit as well as the correct seal and dust cap for my trailer. I was also disappointed when the EZ LUBE dust cap I purchased did not come with the rubber access plug. I got it put back together, and with a little duct tape to cover the dust cap, the tractor will be moved tomorrow. 107514
