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"

Install this hub-and-drum assembly on your trailer. Compatible with electric or hydraulic brakes. Fits 7,000-lb axles. Inner bearing (25580) and race, outer bearing (14125A) and race, grease seal, grease cap, and nuts for 9/16" studs included.


I replace my brakes every 3 or 4 years. It's almost impossible to find a shop that CAN or will turn the inside face where the magnet wears so replacement is the only option. These are a great deal & work well. ALWAYS be sure to get the correct stud diameter when you order!



Still working fine. about due to repack the bearings but Ill wait for warmer weather.


Much easier to replace the whole assembly, one year later trailer brakes working great…


A direct replacement for the original hub and drum assemble. Bearings are pre-greased so installation was quick and easy. Shipping was fast, customer service was excellent and reasonably priced.


Purchased as a spare in case of issues while on long trips with drag car and trailer. New trailer 8 lug and old spare was a 6 lug. Needed one quickly before long trip a week away. You had it in stock and shipped free in two days. Great prompt service. Much appreciated.


I purchased 4 of these wheel assemblies for my 1993 boat trailer. It was far cheaper to replace the entire assembly than to buy all the peices and put it together myself. The parts were all high quality, and included evrything except the headache of assembly. I'll be back in 20 years or so. :)



The items mentioned are still working well. I have been so pleased with my etrailer purchases that we bought 4 new tires and rims from you this spring. Paid less for 4 tires and rims than the local dealer wanted for two tires, no rims.


The best way to do a brake job on a trailer…replace it all, quick, inexpensive, easy!


Great replacements for worn drums/hubs. Most machine shops can't/won't turn the magnet surface so replacement is the best solution. There are 3 size of studs listed, be sure you order the correct studs for your application. Nice having bearings & seal included in one package. Be sure to clean the machined surfaces in the drum with brake cleaner or lacquer thinner to remove the preservative. Pack the bearings with grease, install the seal and you are ready to go!


I purchased new brakes for my boat trailer, electromagnetic drums and the price and quality were excellent. Had one small issue with the packaging and it was promptly corrected.

I would highly recommend etrailer!!


Worked great easy to install.


All of the items we ordered for the goose neck trlr. seemed to be a great product. The hubs, brakes and bearing buddies looked and felt to be a superior product. We would definitely would purchase these items again if needed. Usage and time will tell the whole story of reliability.


Didn't know it came with the nuts and c aps


Very fast shipping ordered it and it went out the same day


Best in the business!


Everything was done easily and delivered on time. Only one problem came about. I opened the package to for the hardware for hubs and one of the seals was damaged very badly and wasn't usable at all. Glad I had one already. Other than that all was good


At this time everything is running well but soon I’ll have the bearings repacked and will know more. Then I can write a better review


Great customer service. Very informative and fast shipping


Excellent parts Fast shipping


I order all my trailer needs from e-trailer they have great quality and fast shipping Thanks etrailer. Doug


The part fits. The price is fair. This is installed and in the field working. Great experience.

Very Fast shipping!

Item was as described and arrived in good condition. Item shipped in a timely manner.

  • Recommended Hub/Drum Assemblies With 8 Lugs For Spindle Measurements
    If you want 1/2 inch lugs for your 8 lug hubs, I recommend the Trailer Hub and Drum Assembly # AKHD-865-7-2-K. If you want 9/16 inch lugs, I recommend hub/drum # AKHD-865-7-1-K. These assemblies come with the bearings and seals to fit your measurements, only taking an educated guess on the seal based on your other measurements. These hubs have zinc-enriched paint to add durability and resist corrosion and they come with the bearings, races, grease seal, grease cap, and lug nuts.

  • Comparing etrailer 7K Trailer Hub and Drum Assemblies with 8 on 6-1/2 Bolt Pattern
    The biggest difference between etrailer hub and drum assembly # AKHD-865-7-2-K and # AKHD-865-7-1-K is the wheel studs. Assembly # AKHD-865-7-2-K uses wheel studs that are 1/2" diameter x 1-5/16" long. Assembly # AKHD-865-7-1-K uses wheel studs that are 9/16" diameter x 1-5/8 long. So you would want to use the one that matches what the wheels require. I have linked video reviews of both for you.

    The Trailer Hub and Drum Assembly # AKHD-865-7-2-K is the same as the Assembly # AKHD-865-7-1-K you found but with 1/2" wheel studs versus the 9/16". We also have the Assembly # AKHD-865-7-2-EZ-K if you need the EZ Lube grease cap to access the grease zerk on your spindle.

  • Trailer Hub for 7k Trailer Axle on Cam Dump Trailer
    Some brands of trailer hubs happen to be more expensive than others is one aspect and some hub configurations are less common so they price ends up being higher. The 7k axle hubs like the # AKHD-865-7-1-K that are a confirmed fit for your dump trailer happen to be a pretty common setup and our etrailer brand does a great job keeping the prices down.

  • 7k Trailer Axle Hub/Drum for Hub with 10-36 Seal and 14125A Bearing
    Based on your bearing and seal numbers the correct hub is the etrailer part # AKHD-865-7-1-K that you referenced. We are able to get a really good deal on our house brand of hub/drums and we decided to pass the savings on to the customer which is why this hub costs a lot less than similar fits.

  • How to Pick Out Replacement Hub for Trailer that Sheared Off Studs
    That's pretty crazy that you ended up shearing off all 8 of your wheel studs. Normally they will break one at a time but not all together like that. This makes me wonder if maybe you were losing them all one at a time until the last few went out together. In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible...

  • How to Determine if a 7K Dexter Trailer Axle Hub has 1/2 Inch or 9/16 Inch Studs
    The only difference between the Dexter 7K hubs and hub and drum assemblies that have either 1/2 inch studs or 9/16 inch studs are the studs themselves. Otherwise they are exactly the same. You can use calipers such as # PTW80157 to measure the diameter of the studs you have. Or you can check the hubs you have for any numbers stamped into them. If you see a 219-04 or 219-09 then it has 1/2 inch studs. If you see a 219-13 or 219-18 they are 1/2 inch. It is also possible that this information...

    For your Dexter 7,000 lbs axles, I recommend the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA. These brake assemblies are side specific and are labeled for you. They are self adjusting after the initial adjustment at installation.

  • How To Use 17.5" Wheels On a 7,000 Lb Trailer Axle
    In order to use 17.5" diameter trailer wheels you'll need to upgrade to 9/16" lug studs. There are no other options as all wheels this size use this size or larger since they are designed for more weight. In order to do this you'll need the Trailer Hub and Drum Assembly part # AKHD-865-7-1-K for standard or part # AKHD-865-7-1-EZ-K for EZ-Lube. Then, you can use a 17.5" diameter trailer wheel like the Aluminum Lynx Trailer Wheel part # 274-000006. I have attached a full list of wheel options...

  • Recommended Hub and Drum Assemblies and Brakes for 7,000 Pound Triple Axle Trailer
    To determine exactly which hubs you need you'll need to find your bearing numbers. Most likely you have # 25580 and # 14125A but verify to be sure. If these are correct you'll next want to find the diameter of your wheel studs and if you have E-Z Lube axles. If the studs are 9/16 inch use # AKHD-865-7-1-EZ-K for E-Z Lube axles and # AKHD-865-7-1-K for standard axles. For 1/2 inch studs instead use # AKHD-865-7-2-EZ-K for E-Z Lube or # AKHD-865-7-2-K for standard axles. Then you need...

  • Running Power Wire to 7-Way on Ford F-150
    The error message is something you'll have to get looked at by Ford or a mechanic, but not having 12 volt power on the 7-way of your F-150 is something you can remedy. What you will do is activate it by purchasing the appropriate amount of 10 gauge wire # 10-1-1 (sold by the foot) as well as 40 amp In-Line Circuit Breaker # 9510 and run the wire from the positive battery terminal through the circuit breaker to the 1:00 pin on you F-150's 7-way, which is the 12 volt circuit.

    Your Lippert Axle uses 1/2"-20X1.99" studs that have a 0.617 knurl for seating in the hub. I can recommend you a replacement hub assembly that does have the 9/16" studs, as I cannot locate any 9/16"-18 studs that have the same knurl dimensions. The etrailer Trailer Hub and Drum Assembly # AKHD-865-7-1-K come preloaded with the 9/16" studs, lug nuts, new races, and bearings as well as a grease seal.

  • Trailer Hub and Drum with 8 on 6-1/2 Bolt Pattern and 9/16 Studs for 7,000 Pound Axles
    The size socket used isn't necessarily going to be the same as the nut or stud thread size. It is usually larger since the outer width of a hex head is larger than the threaded diameter. Hub and drum assembly # 8-219-13UC3 for 5,200 to 7,000 pound axles does indeed have a stud diameter of 9/16 and would take 9/16 inch lug nuts. We also have the similar etrailer model, # AKHD-865-7-1-EZ-K, that also has 9/16 inch studs. Both it and the above assembly are for EZ Lube axles. If your axles...

    Trailer Hub and Drum Assembly - 7,000-lb Axles - 12" Diameter - 8 on 6-1/2 Item # AKHD-865-7-1-K will accept hub-centric or lug-centric wheels. There is also no restriction on use with dually wheels as long as everything is within the capacity of the lowest rated component in the system. I have linked a couple of videos on this hub and drum assembly for you. If you also need brakes the drum accepts 12x2 inch assemblies such as # AKEBRK-7R-SA for the right and # AKEBRK-7L-SA for the left.

  • Is Hub Replacement Required for 15 Inch Wheels to be Upgraded to 16 Inch Wheels?
    To upgrade from a 15 inch wheel to a 16 inch wheel you won't need to change your hubs for a new bolt pattern. If you want to change your hubs for a different bolt pattern you will need the numbers on the inner and outer bearings as well as the seal of one of your hubs. I'd be happy to help with those numbers to determine if there is a fit. We do have 16 inch tires and wheels that fit that 6 on 5-1/2 inch bolt pattern if you want to keep the hubs you currently have.

  • Replacement Hubs for 7,000 Pound Axle With 15123 Outer and 25580 Inner Bearings
    The answer to your question depends on the bolt pattern you need. We have one hub that actually uses a # 15123 bearing which is the # 8-174-5UC3. This has a 5-spoke utility bolt pattern. More than likely you have an 8 on 6-1/2 bolt pattern on your trailer. If that is the case you can use the # AKHD-865-7-1-K. The # 14125A outer bearing has the same 1.25" inner diameter so it will fit your spindle. However, I recommend measuring to find the inner diameter of your grease seal. The included...
