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"

Average Customer Rating:  4.2 out of 5 stars   (22 Customer Reviews)

The rating is for etrailer, not the product. The Dexter hub and drum assembly was fine, etrailers way of doing business is not. The estimated ship date kept changing due to a "location in warehouse" issue. It took 2 weeks before they shipped it out. Bottom line, if you need something in a timely fashion, look elsewhere.


great time of shipment so i can get my trailer back on road .will defnetely use you again thanks stacy happy camping wish i were camping with you joseph

Missing all the pieces


Everything fit perfect. Made a tough job in remote worksite quick and easy.


Still running good after 1 year. Probably around 90k miles on it so far. No complain


Everything arrived in a timely manner. However one of the bearings was damaged half of the Lugnuts were missing because the box that was shipped in was destroyed by the time it got to me. Didn’t have time to deal with having new stuff sent I was able to get a new bearing locally other than that fit was good


Great product and quick delivery





Parts arrived in time and was just what we needed. Quick and accurate ordering system.

  • 10k Dexter Replacement Hub for a 8-415
    I did some checking and the hub/drum we offer that will work for you is the part # 8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS setup. The part number for the ABS version is part # 8-430-7 which we do not carry at this time.

  • Hub and Drum Assembly with 8 on 6-1/2 Bolt Pattern for Dexter 10,000 Pound Trailer Axle
    The Dexter 8-427 hub is no longer available. Even looking through Dexter's site the only references to it are replacement bearings. You can use a wheel with a larger pilot hole as long as the wheel attaches to the hub using lug nuts and not bolts. Hub and drum assembly # 8-430-5UC3 uses lug nuts to secure the wheel to the hub and uses inner bearing 387A and outer bearing 25580.

  • Do Oil Bath Hub and Drum Assemblies Come Pre-Assembled
    All of the oil bath hub drum assemblies that we carry, like part # 8-430-5UC3, require you to install the bearings and seal on them. This is actually really common among even standard grease variations as well. We do have a handful of grease options that come pre-assembled but the vast majority require assembly.

  • Why Are There Different Brake Drums for 9,000 and 10,000 lb Axles After July 1, 2009?
    The Dexter Trailer Hub/Drum Assembly # 8-430-5UC3 is a one piece assembly, hub and drum together. It fits Dexter 9k and 10k general duty axles made after 07/01/2009. Hub # 8-288-3UC1 is a 2 piece for 9K axle (after 10/89) and 10K axle (through 7/1/09). It does not come with the drum or mounting bolts. Dexter changed their spindle diameters on these two capacity (9,000 and 10,000 lb) axles. The biggest difference was in the inner diameter of the seal needed.

  • Availability of Just 10k Dexter Hub for Axle Made Prior to 2009
    For just a 10k Dexter hub for an axle made prior to July 2009 we have the part # 8-288-3UC1 which does not come with the drum. We don't have a version without bearings.

  • Electric Drum Brake and Hub/Drum for 10K Axle
    I linked our main page for all electric drum brakes rated for a 10K axle. These are all 12-1/4-inch diameter but vary in width; 3-1/2-, 3-3/8- and 4-inch widths are available. We have these in both manual-adjust and self-adjust types. For example, part # AKEBRK-10 is a high-value pair of self-adjusting left- and right-hand brakes in the 12-1/4 x 3-3/8 inch size which fits wheels 15-inches in diameter and larger. These brakes use a 7-bolt mounting pattern. We do offer a 10K oil bath type...

  • Determining the Weight Capacity of Axles and If Hubs Are Available
    Unfortunately we don't carry hubs above 10K. The largest hubs we carry are 9K-10K Dexter Hub and Drum Assemblies # 8-430-5UC3. I have no way of knowing what hubs may work on your trailer unless you measure the spindles using a digital caliper like # PTW80157. I've attached a photo to assist with the locations. These measurements will possibly help to determine the capacity of your axle, but any hubs that may fit will limit your axle capacity to the max capacity of the hubs.

  • When is Wheel Retainer Ring Needed for Dexter Hubs and Wheels
    The wheel retainer ring that is included in certain hub assemblies like the Dexter # 8-430-5UC3 that you referenced will be installed on dual wheels when tapered coned lug nuts like # 6-109 are used instead of flange wheel nuts. It essentially allows you to use a lower torque spec for the nuts which would be required when using coned nuts.

  • Replacement Hub Drum for Dexter 10k Axle
    You could take the drum to a machine shop that can turn drums to see if it's good or bad, but typically if you can tell yours is warped it's probably time to replace it. For a 10k Dexter brake drum we have the part # 8-430-5UC3 which is an exact replacement.

  • Do You Have Trailer Hub Assemblies Rated For 8,500 lb Capacity?
    We currently have two trailer hub assemblies that will work with that weight capacity. We have the Dexter Trailer Hub/Drum Assembly - Non-ABS Drum - 9,000 - 10,000-lb Axles - 8 on 6-1/2 - Oil Bath # 8-430-5UC3 and the Dexter Trailer Hub Assembly - 9,000-10,000-lb Axles - 8 on 6-1/2 - Oil Bath # 8-288-3UC1 which is an idler hub (no brakes). Both assemblies use the 2.250 inch inner diameter for inner bearing and 1.750 inch inner diameter for the outer bearing. The oil seal has an 2-7/8...

  • Replacement Wheel Studs for Dexter P-12 D90 Axle
    Thanks for the photo. It gives me the further information needed to assist. The P-12 only gives the factory location from Dexter. The D-90 model is a huge help as it designates is a 9k axle. The correct hubs you would need for your Dexter D-90 axle is the part # 8-430-5UC3. Then the wheel stud replacements are # 7-223 for a 2 inch length or # 7-257 for a 2-1/2 inch length.

  • What Bearings and Grease Seals Does a 10,000 Lb Trailer Axle Use
    If you have a standard 10,000 lb trailer axle then you will need to use a 387A (2.250") inner bearing, 25580 (1.750") outer bearing, and a 10-51 (2.875") grease seal like what is included with the Dexter Trailer Hub and Drum Assembly part # 8-430-5UC3. However, not all 10,000 lb trailer axles use the same bearings and seals therefore you will be wise to measure the spindle where the bearings and seals ride with a digital caliper like part # 301-17068 beforehand.

  • How To Find Correct Replacement Hubs/Drums for Dovetail Gooseneck with Dexter Dually Axles
    It's very likely you have a Dexter 9K or 10K General Duty Axle therefore for a replacement hub/drum you're looking at the Dexter Trailer Hub and Drum Assembly for 9K to 10K Axles part # K08-288-90 or part # 8-430-5UC3. These are both oil bath hubs with an 8 on 6-1/2" bolt pattern. In order to confirm you'll have to crawl under the trailer and read the axle tag to see what brand/capacity they are as well as the date of mfg.

  • Can a 1-Piece 9K/10K Dexter Hub and Drum be Replaced with a 2-Piece 9K/10K Hub and Drum
    I spoke directly with my technical contact over at Dexter. Basically you cannot replace an 8-430 hub with an 8-288 hub due to differences in the spindles that each of those hubs fit. If your axle was made after July of 2009 then you will need to use # 8-430-5UC3. If it was made before July of 2009 you would instead use # 8-288-3UC1 with drum # 9-44-1 for non-ABS systems or # 9-44-3 for ABS systems.

  • How To Determine The Correct Wheel Hub And Drum Assembly For Big Tex AC20 Car Hauler Trailer
    We do have some options that might work for you. To be certain of the right choice, you will need to know your bearing sizes and the manufacturing date of your axle. Details about your axle can be found on a sticker or plate that will be on your axle (see picture). If your Dexter axles were manufactured prior to July 2009 and your inner bearing is like Item # 387A and your outer bearing is like Item # 25580 then the Dexter Trailer Idler Hub Assembly, # 8-288-3UC1, will work for...

  • Replacement Hub and Drum for Dexter 10K Axles with 008-214-05 Hubs
    The hub you need is # 8-214-5UC1. Since it is separate from the drum you would not need to replace both unless it is time to replace the drum as well if it is worn or damage. If it is then the drum part is # 9-27-1. We also have the mounting bolt for this hub assembly, # 7-103.

  • Timbren Axle-Less Trailer Suspension System w/ Electric Brake Hubs to Replace 2800 lbs Dexter Axle
    Thanks for the pictures, they were very helpful. I have a great solution for you but no, they do not make one piece axle and brake assemblies that will fit your spring spacing. I recommend the Timbren Axle-Less Trailer Suspension System w Electric Brake Hubs item # A35RD545E. The individual suspension units replace your existing axle and operate independently. The 4" drop spindle should match up with your existing axle and provide the same ride height. They will fit any frame width and...

  • Replacement Hub and Drum Assembly for a Dexter 10K General Duty Axle 387A Inner and 25580 Outer
    We have exactly what you are looking for. If your axles were made before 07-01-2009, then you have the old style 2-piece hub and drums, so you will want the Complete Hub Assembly, # 8-288-3UC1. Keep in mind, this does not include the drum. If you also need the drum, then you will want part # 9-44-1 for a non-ABS drum or part # 9-44-3 for a drum with the ABS exciter ring installed and 8 drum mounting bolts, # 7-245.

  • Is Dexter Trailer Hub/Drum Assembly # 8-430-5UC3 a 1-Piece or 2-Piece Assembly
    Dexter Trailer Hub/Drum Assembly # 8-430-5UC3 is a one piece assembly, hub and drum together. It fits Dexter 9k and 10k general duty axles made after 07/01/2009. Hub # 8-288-3UC1 is a 2 piece for 9K axle (after 10/89) and 10K axle (through 7/1/09). It does not come with the drum or mounting bolts. For a non-ABS drum use # 9-44-1. For an ABS version use # 9-44-3. And for the mounting bolt use # 7-245 (quantities of 1).

  • Will Dexter 9K - 10K Hub and Drum Fit Lippert 10K Axle
    Hub and drum assemblies, like the Dexter # 8-430-5UC3 you referenced, are universal so they typically fit any 9K - 10K axle just fine. With that being said, there are some exceptions out there so you just need to confirm that your axle uses a # 387A inner bearing, a # 25580 outer bearing, and that the inner diameter of your grease seal is 2.875" to ensure that this fits. Pull your current hub and check the numbers on your bearings to confirm this. If you can't find the numbers then Lippert...

  • Correct Replacement for Dexter Hub/Drum 8-415
    I was able to cross reference the Dexter Hub/Drum 8-415 to the Dexter Trailer Hub Drum Assembly part # 8-430-5UC3 which should be an exact replacement. I don't have any depth measurements of the above/drum but what you would need to measure to confirm is the inside of the contact surface on the hub where the shoe rides and this should measure 12-1/4" x 3-3/8". If so, you should be good to go. In regards to braking assemblies, the best option we have is the Dexter Brake Kit part # 23-450-451...

  • What is the Capacity of a Dexter P-12 Model D100 Axle
    It looks like you're likely trying to replace your hubs/drums on your Dexter axle and I do believe that the "0100" you found on the spec plate actually reads "D100" since that was one of the models that Dexter had for this particular line of axles; I've confirmed this with Dexter as well. These axles were 10k axles and they came in both a general duty and a heavy duty model with the 10k capacity.

  • Can Dexter 10k Disc Brake Setup be Converted to Electric Drum Brake
    Yes, you can replace the hub and brake components of a Dexter 10k axle with drum components to convert it to electric drum brakes. For that you'd need the hub/drums part # 8-430-5UC3 and then for the brake assemblies # 23-450-451 and you'd be set in that regard. You'd need to run 10 gauge or thicker wire to each assembly which we offer with the part # 10-1-1.
