Thoroughly Tested for Safety

This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.


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 etrailer Trailer Hubs and Drums - Hub with Integrated Drum - AKHD-865-8-K Review

Today, we're going to take a look at the twelve and one quarter inch trailer hub and drum assembly for 8,000-pound axle. Has the eight on six and a half inch bolt pattern. Now, this trailer hub and drum assembly includes the bearing races, which are pre-installed. You can see the outer bearing race right here, already installed in the hub, and if I spin this around, if you look in the back, the inner bearing race is already installed in there. Comes with both the inner and outer bearings. Comes with the grease seal, the grease cap, and the lug nuts.

Again the application for this is the 8,000-pound axles. Has the bolt pattern of the eight on six and a half inch bolt pattern, and when they call this the size of twelve and a quarter inches, basically what it is, is it's the diameter, the inside diameter of the drum itself. If we put a ruler and measure from the inside, you can see right at twelve and a quarter inches for the diameter. It comes with the inner bearing, which is the larger of the two. It's part number 25580. Has an inner diameter of 1.75 inches.

The inner bearing is designed to go right into the inner bearing race, just like that. It also comes with the grease seal. The grease seal has an overall diameter of 3.376 inches. That is designed to go right over there and then you tap that in place, so it holds all that in there. It comes also with the outer bearing, which is the smaller of the two.

The outer bearing is part number 02475, has an inner diameter of 1.25 inches, and that'll go where the outer bearing race is, so that bearing would go right in there. Then you have the grease cap, and the grease cap has a flange diameter of 2.722 inches, and that's designed to go right over there once that's all installed. It also comes with the eight lug nuts, and they're a size nine sixteenths by 18 size. The lug nuts are used as once this is installed on over your brakes on your trailer, put your wheel up on the studs here, and then use these lug nuts to tighten them down to hold your wheel and power assembly to your drum, and you just tighten them down to the correct torque specs for your application. That should do it for the review on the twelve and one quarter inch trailer hub and drum assembly for 8,000-pound axles with the eight on six and a half inch bolt pattern. .

Was happy with the service and products. There was a delay with shipping due to a mailing address issue but once it was brought to their attention, they were quick to respond and I received the parts fairly quickly after that. I was very happy about how they resolved the issue. One of the bearings was damaged during shipping but not a big deal as we could find the bearing locally anyways. Will use etrailer again when the need arises. 361542

Do you have a question about this Trailer Hubs and Drum?


  • Needing Replacement Brake Drums With 5/8 Inch Wheel Studs on 8,000 Lbs Axles
  • The brake drums that we carry for the 8,000 lbs axles come in two types, grease or oil bath style. The drums that have the 5/8 inch wheel studs, like # 8-285-10UC3-A, are for the oil bath style drums.The grease lubed drums, like # AKHD-865-8-K, are using 9/16 inch wheel studs. If you have the 5/8 inch studs, then you will need # 8-285-10UC3-A. The drums will come with new lug nuts, bearings, and seals. The only difference is these drums are designed to use oil instead of grease. You...

  • Weight of 8 Lug Hub and Drum Assembly for 8,000 Pound Axle
  • I am not sure of the exact model hub and drum assembly you have on your trailer, but the etrailer.com Trailer Hub and Drum # AKHD-865-8-K that we have for 8,000 pounds axles weighs around 68 pounds. Looking through the other similarly rated hub assemblies we have available, it looks like they all have a weight of around this number. With that being said, it does look like our hubs are a bit different than what your trailer is currently equipped with based on the picture you attached. Your...

  • Recommended Trailer Hub To Convert Trailer From 5 Spoke Wheels To 8 x 6.5 Pattern
  • Based on the information you provided, I recommend the Etrailer Trailer Hub and Drum Assembly Item # AKHD-865-8-K. This hub-and-drum assembly fits 8,000-lb axles (will work on your axles but limited to capacity). It includes an inner bearing (Item # 25580) and race and an outer bearing (Item # 02475) and race, grease seal, grease cap, wheel bolts, and lug nuts. It fits an 8 on 6-1/2 inch bolt pattern. Make sure to confirm that these parts will work with your bearings and trailer....

  • Upgrading From 7K to 8K Electric Brake Assemblies on Trailer for Increased Braking Power
  • You should be able to change out the backing plates, hubs, and brakes on your trailer so you can upgrade to higher rated assemblies, but I do recommend checking a couple things on your tow vehicle first. It's possible that your weak braking is due to a wiring or brake controller issue on the vehicle. If this is the case, changing out the brake assemblies on the trailer won't resolve the issue. I first recommend testing the vehicle side 7-Way with a Multimeter like # BTMT15. Make sure...

  • Replacement Brake Assemblies and Hubs for 2008 Double Tree 5th Wheel Trailer
  • We have the hub you are in need of as part # AKHD-865-8-K and then for the brake assemblies you'd need # AKEBRK-8R for the right hand side and part # AKEBRK-8L for the left hand side. Our etrailer.com brand axle components are actually rebranded Axletek products.

  • Trailer Tire and Wheels for Single Axle 8,000 lb Dump Trailer
  • While we do have what will work for you, both the wheel and tire need to have the capacity to handle that much weight and if you have 15 inch wheels, there are no tires that will fit which have the needed capacity. We also do not carry any wheels with a 6 bolt pattern that have the needed 4,000 lb capacity so you would need to change your hub to one with an 8 on 6-1/2" bolt pattern. That would allow you to use the Provider ST235/85R16 Radial Trailer Tire w/ 16" White Mod Wheel # TTWA16RGWMHD...

  • Diameter of Hub Bore on the Hub Part # AKHD-865-8-K
  • The bore diameter of the hub part # AKHD-865-8-K that you referenced is 2.722 inches and comes with a grease cap that is designed to fit it. If you were asking this so that you could fit a Bearing Buddy to this hub you would want the part # BB2717SS for the correct fitting Bearing Buddy.

  • Do 9k and 8k Trailer Hubs Take the Same Dimension Brake Assemblies
  • The brake assembly dimensions of the 8k and 9k Dexter trailer brake assemblies are the same at 12-1/4 inch diameter by 3-3/8 inches wide. So if you find a brake drum that matches the bearings it will still work even if it's a higher capacity since the hub is going to fit the spindle and the depth and diameter of the drum will be same.
