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"

Best price, fast delivery, part fit exactly how representative said it would… probably the best experience i have had with online shopping and dealing with reps.


Arrived on earlier than expected. The drums are heavy duty. Everything went together perfectly.
Excellent support from the team at eTrailer. Customer service is outstanding,


Order was received in excellent shape and received quickly after placing same.
Great Job by


Great replacement for my 25yr old drums

After a year and 10k miles they still work great. Most of our towing is in the Blue Ridge Mtns and this puts a lot of stress on the drums. No warping, broken studs or any signs of problems
Phillip - 04/07/2019


Bought as replacements for a set of 30yr old Drums. Perfect replacements .


good fit.

  • Trailer Hub Recommendation that Fits Spindle with 1 inch Bearing Diameter
    For an idler hub that has the bolt pattern you need of 5 on 4-1/2 inches and fits a spindle that measures 1 inch for both bearing surfaces we have the part # AKIHUB-545-2-1K. If you needed a brake drum hub you instead would want part # AKHD-545-2-1K.

  • How To Add Brakes to a 2009 Forest River Flagstaff MAC 208
    The 2009 Forest River Flagstaff MAC 208 did not come from the factory with electric brakes as standard equipment. In order to add some you'd likely need the Electric Trailer Brake Kit part # AKEBRK-2 and Trailer Hub and Drum Assembly part # AKHD-545-2-1K for L44643 (1") bearings or part # AKHD-545-2-2K for L44649 ("1.063) bearings. If you don't know which bearings you have you'll need to pop off the hub and measure. In order to complete the swap you'll also need the etrailer Trailer Wiring...

  • What Hardware Needed to Mount 7-Inch Trailer Brake Assembly
    The nuts and lock washers needed to install a 7 inch brake assembly to the brake mounting flange is part # BRKH7 which includes enough hardware for 2 brake assemblies. I'm not certain what you mean by 'drum without a hub'. If you're talking electric drum brakes, the 7 inch hub drums we offer are one integrated piece like # AKHD-545-2-2K which uses the L44649 inner/outer bearing or # AKHD-545-2-1K which is compatible with the L44643 inner/outer bearing.

  • Replacement 7-Inch Hub/Drum for 1993 Coleman Cape Cod Pop-Up Tent Trailer
    My research indicates that the Coleman part 4716A1071 refers to a Dexter 7 x 2-inch hub/drum with a 5-lug pattern. We have several options in this size hub/drum that are displayed on the linked page; all have the 5-on-4-1/2 bolt pattern and all are rated for 2K axles. We have hubs for both standard spindles and also for EZ-Lube spindles. All you need to do to select the correct replacement hub/drum is confirm which bearing is used in yours. It should be either # L44643 or # L44649 since...

  • How to Verify a Hub Fitment on a Spindle
    There isn't a spec sheet or anything of the like to verify the fitment of a hub like the Trailer Hub and Drum Assembly - 2K Axles # AKHD-545-2-1K, and there are only a couple ways to do so. You need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you can't, you do need...

  • Trailer Hub That Fits BT8 Spindle for 2,000 lb Trailer Axles TRU59FR
    There are a number of different trailer hubs that fit the BT8 Spindle for 2,000-lb Trailer Axles # TRU59FR, though none with a 5 on 5-1/2" bolt pattern. The reason is that this spindle requires hubs with inner and outer bearings L44643, which are 1.000" diameter, and those all have a 5 on 4-1/2" bolt pattern; here are the hubs that fit: - Trailer Hub and Drum Assembly - 2K Axles # AKHD-545-2-1K - Trailer Idler Hub Assembly for 2K Axles - 8" to 12" Wheels # AKIHUB-545-2-1K - Trailer...

  • How to Select Replacement Hubs for Utility Trailer
    You can change your utility trailer's hubs from the 4-on-4 wheel bolt pattern to the 5-on-4-1/2 pattern by selecting new hubs that use the same set of bearings as your current ones. The linked photo shows you the usual placement and appearance of bearing part numbers. Once you pull a hub and note the bearing numbers you can refer to the replacement hub page I linked for you. Just click on your inner and outer bearings to see all the hubs that use those same bearings and that will fit on...

  • How To Add Brakes To 2K Axles with BT8 Spindles
    The first thing you'll need to do is weld-on a brake mounting flange like the Brake Mounting Flange part # 4-34 to the spindle. Then, you can obtain new braking assemblies, the Electric Trailer Brake Kit part # AKEBRK-2. In order to use these, you'll also need new hubs/drums as well for which I recommend the Trailer Hub and Drum Assembly part # AKHD-545-2-1K. The 7" hub/drum assemblies are only available in the 5 on 4-1/2" pattern.

  • Trailer Hubs That Use Bearing L44643
    We have a number of hubs that use inner and outer bearing # L44643 and they are shown on the page I linked. These include both idler hubs like # AKIHUB-440-2-1K and hub/drums like # AKHD-545-2-1K. We have these in both 4-on-4 and 5-on-4-1/2 bolt patterns. Please refer to the linked article. All hubs include bearings, races, seals and we indicate the wheel sizes that are compatible with each one. You can click on your bolt pattern and your wheel size to narrow the items to what is compatible...

  • What Wheel Bearing Fits a Timken 07204 Race With a 1 Inch Axle
    From what I could find, the Timken 07204 Race has an outer diameter of 2.047 inches. The race that come with # DL21792 would have an outer diameter of 1.980 inches. This would be the closest option we have available. I can suggest a few replacement hubs that fit the 1 inch axle, however. If your wheels have a 5 on 4 1/2 bolt pattern, you would need either # AKHD-545-2-1K or # AKIHUB-545-2-1K. If you have a 4 on 4 bolt pattern, you would need # AKIHUB-440-2-EZ-1K. You can verify the bolt...

  • Recommendation For Adding Electric Brakes To Rear Axle With Hydraulic Discs On Front Axle
    It sounds like your hydraulic brakes are not working properly as they should work well with or without a load, but if you have a surge coupler that may be the reason why you see more braking with more weight. You can add electric brakes to your other axle if you so desire. This will give you braking with a lighter load and is adjustable on your brake controller for desired functioning as a combined system. For a brake controller, I recommend the Tekonsha Prodigy P3 # 90195. This...

    We do offer some items that might work. The first part you will need is the BT8 Spindle for 2,000-lb Trailer Axles - 1-1/4" Diameter, part # TRU94FR. This would be welded to your square tubing, you would need to make sure that is welded flush. Next, you would need the Trailer Hub and Drum Assembly - 2K Axles - 7" Diameter - 5 on 4-1/2 - L44643 - Pre-Greased, part # AKHD-545-2-1K.

  • Electric Brakes for 10 Wheels on a Snowmobile Trailer
    The Electric Trailer Brake Kit # AKEBRK-2 that you referenced should be the correct size to replace your hydraulic brakes for your 10" wheels. You can quickly verify this by measuring the diameter of your current brakes. You should be able to use the Trailer Hub and Drum Assembly # AKHD-545-2-1K but you need to verify that the # L44649 inner and outer bearings match what you currently have as well as the 5 on 4-1/2" bolt pattern.

    For a 2,000 lb trailer axle we do have hub/drums with a 5 on 4-1/2 inch bolt pattern that will fit and work well and are compatible with 15 inch wheels like you have. For that you'd want the # AKHD-545-2-1K for the hub/drum that will fit on your axle and then for brake assemblies you'd want the # 23-48 for the right hand side and # 23-47 for the left hand side.

    Yes, brake flanges could be added to the Dexter Trailer Axle Beam with Standard Spindles # T20BTR-6048 with the part # 4-34. Then for hub/drums you'd need the part # AKHD-545-2-1K and for brake assemblies # AKEBRK-2R and # AKEBRK-2L. The flanges need to be professionally welded on since they have to be perfectly square.

    We definitely have options to upgrade your current wheels. You will want to make sure you have at least 3 inches of clearance from the top of the tire to the bottom of the fender, but if you have the ability to modify the fender, this should not be much of an issue. You can also stick with the 4 on 4 bolt pattern if you like, but swapping that to the 5 on 4-1/2 bolt pattern will allow for even more options.

Since the vehicle already has a factory 4-flat, you would just need to add the 7-way and wiring along with the controller.

  • Trailer Brake Hub/Drum Compatible w/ 23-47 and 23-48 Brake Assemblies
    The hub/drum you need will depend on the reference number that's stamped on your inner and outer wheel bearings. If your inner and outer bearings are L44649, then you can use # 8-257-5UC3-EZ for an EZ Lube spindle (with the grease zerk on the end of the spindle) or # 8-257-5UC3 for standard spindles. If your inner and outer bearings are L44643, use part # AKHD-545-2-1K. All the hub/drums mentioned above are compatible with the brake assemblies you mentioned.
