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


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 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!


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!


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!


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


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!


The hubs were exactly what I needed and arrived sooner than promised.


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.


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.


Great product


good performance, very simple operation.


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.


Great Customer service


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!


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!


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


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


Product was exactly what etrailer promised. Service was exceptional.


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


Good quality heavy duty hubs, fit perfect, and work well.


Great Service, great products. Would highly recommend!


should last forever


These drums fit to my axle without hesitation. They were exactly as they were stated online.

  • Recommended Hub And Drum Assemblies With 5-On-5 Inch Bolt Pattern
    I've attached an article to help you with how to measure to determine your bolt pattern. With 3 inches on center, you have a 5 on 5 inch bolt pattern. The 5 on 5 bolt pattern is generally only found on 3500 lb axles. For a hub and drum assembly, I recommend the Trailer Hub and Drum Assembly - 3,500-lb E-Z Lube Axles - 10" Diameter - 5 on 5 # AKHD-550-35-EZ-K if you have the EZ lube spindles or the Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 5 on 5 # AKHD-550-35-K...

  • Replacement Trailer Hubs with Bearings L68149 and L44649 that is Pre-Greased
    For the correct hub/drum you'd want the part # AKHD-550-35-K which comes with the bearings you said you needed as well is pre-greased. If you were wanting an idler hub instead you'd want the part # AKIHUB-550-35-EZ-K.

  • 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...

  • 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 #...

  • Replacement Drum Assemblies for AL-KO 8490 Hubs
    According to my research, AL-KO 8490 references an AL-KO hub for 3,500 lb axles with a 10 x 2-1/4" drum and a 5 on 4-1/2" bolt pattern. For a drum assembly that will work with these hubs I recommend taking a look at the Electric Trailer Brake Kit part # AKEBRK-35-SA for self-adjust or part # AKEBRK-35 for manual adjust. If you would also like to replace the hub then as long as your existing AL-KO hub uses an L68149 inner bearing and an L44649 outer bearing, the Trailer Hub and Drum Assembly...

  • Do Trailer Hubs # AKHD-545-35-EZ-K and # AKHD-550-35-K Fit Same Spindle
    Both hubs you mentioned fit the same size spindle so they would be interchangeable, but since you want a 5 on 5 inch bolt pattern the hub/drum you'd want is the part # AKHD-550-35-K actually. I also attached a help article on converting a trailer to electric over hydraulic drum for you to check out as well.

  • 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.

  • Availability of Trailer Hub/Drum that Has Chevy 5 Bolt Wheel Pattern
    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.

  • Do all 3,500 lb Trailer Axles Have the Same Bearings
    In almost all cases 3,500 lb axles will all use the same bearings. If your trailer has a Lippert or Dexter 3,500 lb axle then yeah they would be the same. But to be safe it won't hurt to pull them off and get the numbers. If you are sure you need a 5 on 5 inch bolt pattern we have the part # AKHD-550-35-K which would work and fit the spindle. This hub uses bearing numbers L68149 and L44649. I attached a help article on bolt patters for you to check out as well.

  • Recommendation for Adding Electric Trailer Brakes to Trailer with 3,500 lb Axles & 5 on 5 Inch Hubs
    For your 3500 lb axles, I recommend starting with the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies # AKEBRK-35-SA. These assemblies will self-adjust to ensure you have the best braking without needing to manually adjust them every few months. Then for your 5 on 5 inch hubs, I recommend the Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 5 on 5 # AKHD-550-35-K.

  • Replacement Hub Not Fitting As Expected
    The brake assembly and brake hub will not meet flush, but they will be close. I would double check that you have the correct parts and that all races and seals oriented correctly and fully seated. Then reassemble and tighten crown nut down until tight, then back off to where cotter pin slots line up. At that point you should be properly assembled. I have attached a photo of an assembled brake assembly and brake hub for you to compare to. You will see that there is a gap.

    I can certainly recommend a Timbren axle-less system for you. The Timbren Silent Ride Suspension does not have a bracket to flip the axle because there wouldn't be a way to attach the system to the frame if the axle is flipped. When you "flip the axle" you are putting the leaf springs or suspension above the axle which is not going to work with the Timbren Silent Ride system.

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.

    I recommend using the Timbren Axle-Less System # ASR1THDS02. This system is similar to the system you were looking at but it has a weight capacity of 2,200 lbs and does not come with any hubs, so you can add compatible 5 on 5 inch hubs like # AKHD-550-35-K to accommodate your Jeep Wrangler wheels since this is the standard bolt pattern for Wranglers. Then for brake assemblies you'd want the part # AKEBRK-35-SA.
