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"

The products I bought were packaged very well, arrived undamaged and fit on my utility trailer perfectly. This is a result of learning about trailer brakes from all the detailed information that is provided by The brakes work great, this was a first time installation of brakes on my trailer. No problems at all. I would recommend you guys to anyone!

Dan S.


The brakes work great! Wish I had Installed brakes on my utility trailer a long time ago. I move a small compact tractor with my trailer. With the brakes installed on my trailer, driving on the road at highway speeds is much safer now. I can stop in a normal distance, where before it was a bit dangerous. Love the performance of them! Thanks for the information you provided which enabled me to figure out what I needed!


At the time I ordered these, I was new to re-doing brakes. I had never done anything like it before. I did my best research. However, I still ordered the wrong parts for my trailer. George and Tamera were extremely helpful in their research! They went out of their way to help me get what I needed. After watching the videos and getting greasy, the job was complete. I may have made mistakes along the way, and I really should have called first, but in the end, my trailer works great.

My trailer - 3 years later - still has no issues and has over 10,000 miles on it pulling my quads.

I have been a satisfied customer since 2015.



I purchased two brake hubs and two electric brake assemblies along with mounting nuts and lock washers. I received them in two days and installed them the same day they arrived. the fit was perfect. I highly recommend these to anyone in need of brake parts.


Happy with all products delivered, including the brake drum hubs. Looking forward to putting the parts on my trailer and correcting several deficiencies. Can't say much about the parts themselves, other than appearance is good, but am very satisfied with the selection, price, speed of delivery and service from I need to do some work on my gooseneck also and will definitely buy from this outfit again. Bragged on them to my co-workers.


5 Star Rating for etrailer and their staff. They have exceeded my expectations on every item I have ordered for my TT. We can go on down the road with the knowledge that the Breaks and bearings systems on our Trailer are in good shape. Great DIY videos and fair pricing. Thanks.


These assemblies were perfect for my application! All of the parts were there and the best part was that the bearing races were already installed making my job much faster and easier! When purchasing any item online you always worry that the parts ordered are the right parts that you need to complete your project. All of the videos and descriptions of e trailer are perfect!!


great price on product, etrailer site gave the information to make sure I got the right part for my application. I would like to see the bearings wrapped better to minimize damage in transport.


Product was delivered in a timely matter and in good condition. I am disappointed that the brake shoe backing plates did not come with new mounting hardware. Now I'll have to try and find the right nuts to fit.


Excellent compliment to the electric brakes I bought.

These pushed on as they should easy peasy.

Worked like a champ.


Delivered quickly and fit perfect...Thanks for the professional site with install videos.


Parts were on time and as ordered. Thank you ! Will use etrailer again whenever I need parts.


Best price I could find. Shipping was out the same day and I received it 3 business days later. Everything looks great and will be a direct replacement.


Great fit, form and function. Mine was hard to find so ordering was my only option and etrailer got it to me quick and complete.


Product delivered as ordered and shipped right away. Great company to deal with! Thank you!


Great product! Fast shipping! Excellent service!


Fit Great! Just what I needed! Super fast shipping!

  • Replacement Hub for 2500 lb Trailer Axle with 5 on 5.5 inch Bolt Pattern
    Are you sure it's a 2,500 axle and not a 3,500? The 2500 isn't a standard one so we'd need to get bearing numbers/spindle dimensions to identify it.

  • Axle-Less Suspension And Electric Brake For Trailer
    I see that you referenced part # ASR5200S01, a 5200 lb axle-less system for your trailer. The Axle-Less systems we offer have bolt patterns of either 5 on 4-1/2 or 4 on 4. We do not currently carry any axle-less systems that have a 5 on 5-1/2 bolt pattern with that weight capacity. I spoke with my contact at Timbren and they told me they do not offer the 5 on 5-1/2 bolt pattern. I have attached a help article that shows how to measure the bolt pattern of a wheel. If you are able to use...

  • How to Determine if Electric Brakes Can be Added to a Trailer
    I will need to know the inner and outer bearing numbers stamped into the sides of the bearings to determine which hub and drum assemblies will fit. It sounds like your spindles have brake mounting flanges already (standard 4 bolt pattern matches your measurements, like # 4-35). So you just need the proper hub and drum assemblies and brake assemblies. I have included a picture that shows where the bearing numbers are located. I have also included a link that explains everything needed to...

  • Converting 3500 lb Axle from Idler Hubs to Electric Brakes
    The brake mounting flanges, whether they be 4 or 5 bolt, have a standard hole spacing to fit their appropriate brake assembly. No worries about the brake assembly matching with the existing one on your axle. A 3500 lb axle like what you have will use a 4 bolt flange. You will need to get the numbers that are stamped on your existing bearings, in order to confirm the fit of the # 84557UC3. Your current bearings will need to match the bearings of the replacement hub. The # 84557UC3 uses...

  • Recommended 5 on 5 1/2" Hub Assembly For Timbren Axle-Less Trailer Suspension System
    That sounds like an awesome project! The Timbren Axle-Less Trailer Suspension System # ASR3500S06 you were looking at can use idler hub's or hub and drum assemblies with 5 on 5 1/2" bolt pattern. If you are planning on adding trailer brakes you will need Dexter Trailer Hub and Drum Assembly for 3,500-lb Axles # 84557UC3 which includes the correct # L68149 Inner Bearing, # L44649 Outer Bearing, # 58846 Grease Seal, and races.

  • Parts Needed to Add Electric Brakes to a Trailer without Brakes
    Unfortunately your pictures are not working, but you provided me with enough information that I can make a recommendation for you. There are a few different parts you will need to add brakes to your trailer that has a 3500 lb. Dexter Axle. Brake mounting flange (which your axle already has), Spindle which we know because you told me you had a 3,500 lb. Dexter axle, Brake assembly (listed below), Hub and Drum (listed below), Trailer wiring (listed below), Breakaway Kit (listed below) and...

  • Dexter 8-249 Trailer Hub And Drum Replacement
    We do have the correct replacement hub and drum for your Dexter 8-249, and there are a couple of options. The only thing that separates them is if you have an E-Z Lube axle (your spindle will have a grease zerk) and what your hub's bolt pattern is. You will want to match your bolt pattern so you can match your current wheels, and you will have either a 5 on 5" bolt pattern or a 5 on 5-1/2" bolt pattern. If you are unsure, I have added a link below to a printable bolt pattern template,...

  • Hub and Drum Assembly Recommendation
    For an idler hub I would recommend that you get a Trailer Hub Assembly, part # 84545BX. This hub has the same inner/outer bearings and seal size as your current hub so it would work well for you. For a brake hub I would recommend that you get a Trailer Hub & Drum Assembly, part # 84557UC3. Both these drum assemblies use the same bearing and seal size that came off of your old hub, so this will work on your spindle perfectly.

  • What is the Bore Size of the Dexter Trailer Hub and Drum Assembly # 84557UC3
    A 1.98 inch inner diameter bore is pretty common on trailer hubs. If you were to measure the bore diameter of the Dexter Trailer Hub and Drum Assembly, # 84557UC3, using a dial caliper, you would get 1.96 inches. This hub requires a grease cap with a 1.98 to 1.99 inch diameter. The grease cap that comes with this hub actually measures 1.99 inches. If you are looking for a replacement dust cover, you have many options. For a standard dust cover, you can use part # F001518 or # RG04-020....

  • Trailer Hub Recommendation for a Trailer with Inner Bearing L68149 and Outer Bearing L44649
    Are the wheels you plan on installing on your trailer wheels that were specifically designed for trailer use? Wheels with that much offset are not usually found on trailers, especially in the diameter you have. Aside from that the Trailer Hub and Drum Assembly # 84557UC3 and the # 84555UC1 would work well since the bearing numbers match what you have as well as the bolt pattern. Just so we're both on the same page, offset is the distance the centerline of the wheel is from portion of the...

  • Option For 3,500 lb Dexter Axle Replacement
    The hub you have is the Dexter Trailer Hub and Drum Assembly # 84557UC3, which is for 3,500 lb axles. The closest option we have to the measurements you mentioned is a 3,500 lb axle that is 74 inches from spring center to spring center, 82-5/8 inches from brake flange to brake flange, and 89 inches from hub face to hub face. This axle - which your hub does fit - is available with either standard or EZ Lube spindles: - Standard Spindle: Dexter Trailer Axle Beam with Standard Spindles -...

  • Can Electric Brakes be Added to Cam Slimeline AG Dump Woodsman Trailer
    The first thing to check on the trailer is if it has brake mounting flanges. A brake mounting flange is welded to the axle/spindle and holds the brake assembly. For an example of what this looks like check out spindle # TRU74FR or # TRU37FR. If your trailer does not have brake mounting flanges you could have some welded on but it is a precision job that requires a professional welder with experience in welding on brake flanges. The easiest solution would be to replace the axle with one...

  • Can Brakes be Added to Trenton AUT1064b Trailer
    I can help you pick out the correct parts to add brakes to your trailer but we don't have the exact parts you'll need without requiring you to do some checking. I attached a link to this page that has a guide which covers the entire process of adding brakes to a trailer. First thing you'll want to do though is determine if your current axles have brake flanges like the four bolt flange you see on the spindle # TRU74FR. From there it's just a matter of picking out the correct hub/drum...

  • Do Trailer Brake Hubs and Idler Hubs Have Same Hub Face Dimension
    The hub face dimensions between idler hubs and brake hubs like the part # 84557UC3 that you referenced is the exact same which means your wheel would not stick any further or less if you went from no brake to a brake axle. I attached a link to a guide that covers adding brakes to a trailer axle for you to check out as well.
