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"

Very easy install for my 3500lb trailer axle. Once I got my brake shoes assembly on these took about another 15minutes to put the 2 grease up wheel bearing in. I recommend getting the bearing packer that will make the job of greasing up the wheel bearing much easier. The whole job with the 2 brake shoes assembly and 2 brake rotor/bearing took just a little over an 1hour. Awesome price on etrailer. Thanks again for the fast and free shipping.
This is what I brought


I just wanted to say thanks to B. for all help she provide. The trailer hubs and drums fit perfectly.
Thanks again.


I ordered drums to replace the old 4 lug 9.44 inch spacing the old drums had. It was a perfect match. My only problem was the old fiberglass travel trailer I was restoring had a wheel well that would only except a 25 inch tall tire at the most. The drums I installed were five lug with 5 in spacing. Only one rim would fit and that was a 15 inch. So naturally I freaked out! I called etrailer and spoke with Ashley. Ashley was very helpful and knowledgeable. I called some of my friends about my possibilities. I was able to find tires that were shorter then 205's etrailer is extremely helpful!


The parts work good, don't trust the emailed paper lug gauge, buy a good one.


Great pro-active customer support. A pleasure working with a company that knows how to actually do online business. The best I have found. I had a couple of questions before the purchase and your tech support was spot on, asking the correct questions, giving the correct information.
Now to the actual product - the drums fit perfect (thanks to the questions and answers from your tech support). The bearings fit the shaft perfectly. I put your companies brake assembly onto a shaft that didn't originally have brakes. All of it lines up great. I was a bit surprised that there wasn't a keeper, a shaft nut, or the nuts for the brake bolts. But that is a small item to pick up at the local hardware store. Thanks again!


This worked great on my trailer. It was a breeze to install. I cleaned the inside with brake cleaner while the seal was still in and then opened it up and slid it on the spindle. Tightened the castle nut and pinned it pop on the dust cover and done. Smooth. I love how fast etrailer ships and the quality of their parts does not disappoint.


Perfect fit and it's painted


The parts were exactly what I needed.


The hub assembly I received worked perfectly and came quickly.


I also bought the self adjusting electric trailer brake kit with the trailer hub and drum assembly. I am very pleased and satisfied with how easily everything went together with no problems. Everything you need comes with the new hub drum assembly. I now have the piece of mind to tow safely with a new and fully functional brake system on my trailer. Everything is very high quality and easy to assemble. I highly recommend it!


Haven't looked at it yet. But Ashley was a blessing, GIVE HER A RAISE. She knows the products, and what you need to get the Job done.


Funny you should ask, I am camped here at Grand Rivers, Ky and brought my harley in the trailer with the new brakes you are asking about. They are working great and have made it much safer to haul my motorcycle or side by side. Very pleased with the product and level of support I received getting them installed. Thanks again for checking, all is working great.


I got this pair of brakes to install on my 16' equipment trailer yesterday and installed both on rear axle today in about 2 hours and everything works as it should. Note; every part fit perfect, my one suggestion to improve this kit would be if you added the 8 7/16" nuts and lock washers but you have a winner.


Quality product. Product was back ordered for some time. In the midst of a messed up economy. E traile came through and my trailer now has new hubs and breakers.


Installed them this morning and they were perfict. I recieved them really quick and they were boxed really well. Thanks Chuck


The drums and backing plate fit like it was suppose to, the dust caps were a little sloppy, once I got them on some fit very snugly but I had a couple that did not.


I would like to thank Ms Bailey B for her tireless, knowledgeable kindness and paitence in helping Me get the right items. She went above & beyond the expected customer service . I am appreciative of the quality products I get from Etrailer and look forward to purchasing from you for my future meeds!
Thank You Team Etrailer & Ms Bailey B for your commitment to excellence!


The products are fine but as a dealer, these constant messages are annoying. We now buy from other sources after repeatedly asking for the follow up messages to stop.


I picked up one of these for a spare to take with me on road trips when I have my trailer. Always good to have spare parts on long trips. Shipping was fast and prompt! Thank you etrailer!


Have had zero issues with these on our car trailer! Would buy again!


Ordered the wrong size trailer hub the first time. No problem returning. Reordered the correct size and it fit perfect! Prices are comparable or lower than other sellers. Shipping was quick. Thanks!


Awesome that they were ready to install. No having to get all greasy.


Great customer service, parts worked as they should. Would order again with no problem.


There hub an brakes fit my trailer just like they should excellent fit


I very satisfied with this product very easy to install and will do this again I have another trailer to do in the future

  • Hub Assemblies For 3500 lb Axle On Tandem Axle Car Hauler 16 Foot
    For a 3500 lb axle, your options for bearing sizes are greatly narrowed down so that makes things a lot easier. You just need to determine your bolt pattern of your wheels. For traditional 5 on 4-1/2 inch bolt pattern, Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter, I recommend # AKHD-545-35-K. For 5 on 5 inches, I recommend # AKHD-550-35-K. For 5 on 5-1/2 inches, I recommend the # AKHD-555-35-K. For 6 on 5-1/2 inches, I recommend the # AKHD-655-35-K. If you have axles...

  • Guide for Adding Electric Brakes to a Trailer
    I attached a help article that would walk you through the process of adding electric brakes to your trailer. Basically you are going to need to find out what hubs you currently have on your trailer so that you can get the correct hub/drum that will fit your spindles and wheels. From there you will be able to pick out the correct assemblies to fit those hubs. The part numbers you referenced would work great for your trailer as long as you can determine that they will fit your spindle.

  • Replacement Hubs and U-Bolt Kit for 3,500 Pound Lippert Axle # LC35212150
    From my research your axle is a 3,500 pound, 2-3/8 inch diameter axle and since you have a 5 on 5 bolt pattern you likely have bearings # L44649 and # L68149. You'll want to verify this is correct with your current bearings. If this is the case for a hub and drum assembly I recommend # AKHD-550-35-EZ-K which is for E-Z Lube axles with a zerk fitting. If you have standard axles use # AKHD-550-35-K instead. If you only need idler hubs use # AKIHUB-550-35-EZ-K with E-Z Lube axles and #...

All of our idler hubs and hub and drum assemblies with a 5 on 5 bolt pattern use a # L44649 outer bearing and # L68149 inner bearing.

  • Recommendations For Replacement And Upgrade Parts For A 2007 TrailManor 3326 Travel Trailer

  • What Type of Wheel Would Need to Be Used with Trailer Hub # AKHD-550-35-K
    The hub part # AKHD-550-35-K that you referenced has a 5 on 5 inch bolt pattern so for a wheel with that matching bolt pattern you'd want the part # AM20538DX and you'd be set. This is a 15 inch diameter wheel that is 6 inches wide. I attached a review video for this wheel for more info for you to check out as well.

    The Chevy 5 bolt pattern can mean a couple different patterns. The part # 84546UC3 is the very common trailer bolt pattern of 5 on 4-1/2 inch. The other common bolt pattern associated with Chevys is 5 on 5 inch like the part # AKHD-550-35-K which would be the other option. If the distance between adjacent wheel studs on your hub is 3 inches you have a 5 on 5 inch. If you have 2-5/8 inches it's 5 on 4-1/2 inch.

  • Adding Electric Brakes to Second Axle of Tandem Axle Carson Trailer
    You can certainly install brake assemblies and drums on the rear axle of your tandem axle trailer, and they'll bolt right up as long as the axle has a brake mounting flange installed on it. If the rear axle uses the same bearings, and the hubs have the same wheel bolt pattern, you can use the same # AKEBRK-35R-SA and # AKEBRK-35L-SA brake assemblies and # AKHD-550-35-K hubs you used last time.
