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 AKHD-550-35-K W80630 AKEBRK-35-SA BIK-00 736723

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! 607952

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! 596292

Everything is very high quality and easy to assemble. I highly recommend it! 589682

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.

  • Replacement Hubs With 5 on 5 Bolt Pattern
    We do have hubs available with a 5 on 5 bolt pattern; they are each compatible with 3,500 lb axles, have inner bearing # L68149 and outer bearing # L44649 and fit wheels that are between 13 inches and 15 inches. You need to take apart your old hub in order to find out if you have the same bearing numbers. If so hub and drum assembly # AKHD-550-35-K will work; for an idler hub assembly # AKIHUB-550-35-K would be the right choice. I've added a link to video reviews of these parts for you...

  • 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...

  • 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.

  • Timbren Axeless Suspension System For 5 on 5 Bolt Pattern Wheels To Help With Tire Clearance
    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. I also checked to see if they had any spacers available to help with tire clearance and they do not. I recommend...

  • 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.

    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.
