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"

Great replacement for my 25yr old drums 493608


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

  • What Parts Are Needed To Add Brakes To A 1997 Coleman Destiny Pop-Up Camper
  • To add electric brakes to the Coleman Destiny Bayport pop-up camper, you will need a few pieces of information. You will will need to know the weight capacity of the axle, bolt pattern of the wheels, and whether or not it has brake flanges already and their bolt pattern. If no brake flanges then you will have to either replace the axle with one that does or you can purchase brake flanges like Item # 4-34 and have a qualified welder weld them to the axle. After sorting out what...

  • 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...

  • 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. You also need a 7-Way connector on your trailer like...

  • 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 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...

  • Parts Needed To Add Electric Brakes & Controller To Trailer Pulled By 2007 Tacoma & Motorcycle
  • Based on the information you sent, it sounds like you have bearing Item # L44643 for your inner and outer bearing. If this is not correct, let me know. With your current trailer setup, we only have idler hubs that fit (link attached). If you are open to changing your wheels to a 5 on 4-1/2 inch bolt pattern then trailer hub and drum assembly Item # AKHD-545-2-1K would work.

  • Parts Needed to Add Brakes 2,000 lb Trailer Axle with 5 on 4-1/2 inch 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.

  • Can Trailer Brakes be Added to Dexter Axle # T20BTR-6048
  • 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.

  • 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. ...

  • 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.
