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.

E-Z Lube-Compatible Assembly for Simple Lubrication

The grease cap on this hub-and-drum assembly is specially designed to work with your Dexter E-Z Lube axle to make lubricating bearings quick and easy. Just remove the plug on the grease cap, attach a grease gun to the zerk fitting on the end of the spindle, and inject the grease. It will flow easily to both inner and outer bearings. Not only does this make lubricating the bearings easy, but it also helps to prevent corrosion of the hub. This is because you can lubricate the bearings without the mess of taking apart the entire assembly.

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"

Actually ordered the wrong bolt pattern but was pleasantly surprised by etrailer’s assistance regarding the return of the wrong hub/drum assemblies as well as the purchase of the correct ones. Great Customer Assistance! These pregreased hub & drum assemblies are a great product making replacing these parts a breeze! Comes with pregreased bearings and seals in place ready to be installed. Couldn’t be easier! Thanks etrailer!

Installed four sets of these hubs and drums, along with new electric brakes, as part of a total trailer refurb a year ago. Had some challenges early on with one wheel overheating, but solved it with the help of etrailer's excellent tech support. Since then everything is fine and I couldn't be happier.

Initially I had some issues with one of the drums getting very hot when driving. So, I contacted customer service, and with their help I was able to rectify the situation. Since then everything is working just fine. Thanks for being a first-class organization who cares about the customer.

Converted Carson trailer front idler axle to electric brakes. Parts fit excellent. Customer service was superb even when I ordered wrong part.(my fault) The return of wrong part was handled very professional. Very happy with Etrailer parts quality and employees.

These were great and came with bearings, dust seals, and new lugz. My old ones seemed a little warped. Nice paint on the outside, time will tell if it stands up to snow and salt.

1 year later and the electric drum I ordered is still going strong. Believe me, I've put it to the test a few times since install.

Thanks George for the service, the 10 inch hub-drum and the 7 pin plug made the trailer rebuild much better. Your company is by far the best I have ever dealt with, I can't say enough about the fast shipping and the quality of your products. I will be ordering more hud- drums for another trailer soon,again thanks.

No problem with them thus far. Straightforward install with the bearings, races, and drums.

The hub and drum assemblies fit well and there was no damage so everything went together nicely. What I have come to expect from etrailer.com!

- AKHD-550-35-EZ-K

Great service and follow up, parts arrived packaged and un damaged after long trip and multiple warehouse/truck transfers. Tracking was spot on so I could plan to put parts on trailer the day they arrived. Hub and bearing assy is the way to go, slide them on and torque up.

Very good quality not as good as the dexter but they work great easily to install

I got the wrong size brake drums because I measured improperly but other than that everything was fine. I added brakes to a trailer that had none. . I had to re-order the right size and now my trailers on the road. My recommendation is to take your wheels down to your local tire dealer and have them measure the lug diameter with their gauge before you order.

Ordered a trailer Drum kit (5 by 5)... came at fair price, I am very pleased.. Shipping was fast and low cost (3 day priority) and was actually here in 2 days (bonus points) The drum coming with the race already pressed in was a huge help to be as I live way out in the sticks and am limited on tools . I will for sure use etrailer again should I need more parts to keep my landscape business going...Thank you

- AKHD-550-35-EZ-K

My original purchase was for a new weld on spindle with new drum/hub assembly with bearings for the other 3 wheels. I measured the wheel pattern wrong and by the time I had realized this I had installed everything. I reached out to etrailer for help and thanks to Hally C. she was able to remedy my issue with the right parts in about two days with little trouble at all. Thank you to etrailer for technical assistance and speedy delivery of new parts. Advice to anyone ordering hubs and drums remember the old saying about carpentry, measure twice and cut once, (in this case measure twice and order once) or you'll be like me and now own a hub/drum that's sitting on your shelf collecting dust because you don't own anything it fits (yet lol)!

The unit came well packed originally and was easy to install. Have used 22' tandem axle to haul mixed loads up to 5000 lbs at least 2 a month since rebuilding it completely and have had no problems stopping. only issue is lost a grease cap plug recently

  • Are Trailer Hub/Drums Directional Like Trailer Drum Brakes
    Trailer brakes are directional, meaning that a trailer should be fitted with correctly matching left- and right-side brakes such as # AKEBRK-35R-SA and # AKEBRK-35L-SA based on the axle weight rating. However the hub/drums themselves, which fit over the brakes, are not directional. In other words while there are left and right brakes, there are no left and right hubs. Hubs should be selected based on the bearing set used. This ensures the hubs fit on the trailer spindles. They also need...

  • Recommended Hubs and Brakes to Build Offroad Trailer with Timbren Axle-Less Trailer Suspension
    Generally, it is not recommended to use automotive tires on a trailer application, with the only exception being LT tires. Based on the information I was able to find, it looks like you're in luck because that's exactly what your BFGoodrich Mud Terrain T/A KM tires are so you should have no problem using those to build your off-road trailer.
