Features to know about
Built for Light-Duty Towing: Fits 2,200-lb E-Z Lube Axles
When you’re pulling a small trailer or pop-up, you need a hub and drum that’s made for your setup. This Dexter hub-and-drum assembly is built for 2,200-lb E-Z Lube axles with BTR spindles and offers a solid braking surface for 7" x 1-1/4" brake assemblies. It fits wheels from 10" to 13", uses a 4 on 4" bolt pattern, and supports up to 1,100 lbs per hub. It’s made from sturdy iron so you get dependable strength for long trips or restoration work.
No-Mess Bearing Service: E-Z Lube Grease Cap Keeps You Rolling
Greasing your bearings doesn’t have to mean tearing everything apart. The included E-Z Lube-compatible grease cap has a removable rubber plug that gives you direct access to the zerk fitting on your spindle. Just attach your grease gun and pump in fresh grease—it flows through to both the inner and outer bearings. That means faster maintenance, cleaner hands, and protection from corrosion inside the hub.
Ready to Install: Bearings, Races, Seal, and Hardware Included
Everything you need to mount the hub comes in the box—inner and outer bearings (L44649), races (L44610), grease seal #10-9, 1/2" wheel bolts, grease cap, and lug nuts. The races are already pressed in, so you can skip the prep work and go straight to assembly. With the correct parts matched to fit a BTR spindle and 1.063" bearing inner diameters, the install is quick and straightforward.
Smooth Braking for Electric or Hydraulic Systems: 7" Drum Surface
The 7" diameter x 1-1/4" wide drum face gives your brake shoes a clean, even surface to grab when stopping. It’s designed to work equally well with electric or hydraulic brakes, so whether you’re upgrading an older setup or replacing worn parts, you get reliable braking response and smooth operation mile after mile.

Determining Bolt Pattern
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Took way too long to ship from the warehouse. Tracking info was not specific and told me two different dates at the same time. I emailed you early in the order procesd and you never replied. I would assume that many of your customers are contractors and need parts in a timely manner. By delaying the shipping, you are delaying someones job. The parts came in dirty. I will not be ordering from you again.

Well after receiving 2 different hubs and unfortunately of course installed the correct one first about 45 minutes or less. Perfect fit and finish. etrailer took care of the wrong hub and when i received it took around 30 minutes to install that side. If you have general knowledge and just a bit of mechanic skill you can do it. Added brakes to my 2008 pop up camper, have driven this over 8000 miles (or more) now and has worked flawlessly. Highly recommend.

New hubs were shipped immediately after ordering and arrived the next day. They fit my 2004 Viking Epic 1706 perfectly. I was able to change them out in about one hour and get on the road to Florida. I re-torqued the lug nuts and checked the hub temperature at every gas fill up and they never got warmer than the tires. Drove 1000 miles in two days with no issues. Thank you etrailer for quality parts at great prices and excellent customer service.

I purchased a pair of these to replace the hubs on my 2001 Jayco popup camper w/Dexter axle. They arrived quickly and included everything but the grease. The races are already installed, which is great. These are EZ lube hubs, but the only difference I could see is the EZ lube dust cap and a different hub seal. I installed these on non-EZ lube spindles and used the bearing buddies I already had. eTrailer was great in addressing the one question I had, the price was great, and I got free shipping with my order over $150.

Perfect fit for my Dexter Model 48424 axle. Assembly was straight forward.
Appears to be a good fit with the AKEBRK-2 break kit. Still have to do a test drive and confirm breaking operation. If that goes as expected this could be 5 stars.

Ive had these brakes for a year now. I am still pleased with them. Although I did have trouble with the Drivers side unit at first. I could not eliminate a squeak when applying the brakes. eTrailer worked with me to resolve the problem. They sent me a total one side replacement. I recently completed a 300 miles trip with the camper and the brakes worked perfectly. No more squeak.

- Adding Brakes to 1999 Jayco Heritage Glacier with Dexter 2,500 lb AxlesA Dexter 2,500 lb axle uses hubs that have inner and outer bearings of L44649 like the part # 8-257-5UC3 which has a 5 lug bolt pattern or the # 8-173-16UC3-EZ which has a 4 lug bolt pattern. These both come with bearings and seals as well. For brake assemblies you'd want the part # 23-47 for the left hand side and # 23-48 for the right hand side and you'd be set. I attached a help article link on adding electric brakes to a trailer for you to check out as well that I think you'll find...
view full answer... - Hubs and Brakes for 2k AxleHey Glenn! There are two standards for 2k spindles. The Dexter Trailer Hub and Drum Assembly # 8-173-16UC3-EZ uses # L44649 inner and outer bearings with an inside diameter of 1.063". If you have # L44643 bearings with a 1.00" ID the only option we have is the # AKHD-545-2-EZ-1K which has a 5 on 4-1/2 bolt pattern instead of a 4 on 4. Both are compatible with the etrailer Electric Trailer Brakes # AKEBRK-2. If you aren't sure about your bearings, you will either need to pull the hubs and...
view full answer... - Recommendation to Replace Brakes and Hub/Drum on a 1976 Apache Royal CamperHey Shawn, thanks for reaching out! Industry standards with trailer parts didn't start to become a thing until about the 1990's which is why you're having such a hard time finding replacement parts. The best solution would be to have a welder cut off and replace your spindles with the BTR E-Z Lube Spindle w/ Brake Flange # TRU27FR and then you can replace the brakes with part # AKEBRK-2 and the hub/drum with part # 8-173-16UC3-EZ. I know it's not ideal but the only alternative is to...
view full answer... - Dexter Torflex #9 1000-2200 lbs Axle Hub and Bearing Kit ReplacementsThe current hub for your Torflex #9 axle uses the inner and outer bearings # L44649 with a grease seal that has a 1.500" inner diameter. You can find the bearing kit as part # BK1-150 on our site. For a replacement hub we have the part # 8-91-05UC1 for a standard spindle or part # 8-91-05UC1-EZ for E-Z Lube spindles. If you have brakes then you would want part # 8-173-16UC3 for a standard spindle or part # 8-173-16UC3-EZ for E-Z Lube spindles. All of these hub kits come with bearings and...

view full answer... - Replacement Axle for Harbor Freight TrailerIn order to find a replacement axle for your Harbor Freight trailer you will need to take some measurements to determine the correct axle length. The most important measurement is the distance from hub face to hub face. Additionally, you can measure the spring center distance.

- Can Electric Trailer Brakes be Added to a Harbor Freight Kit TrailerNeither of those Harbor Freight trailers has brake mounting flanges on the spindles. To add electric brakes you would have to have brake mounting flanges welded on. This is a precision job that requires a special jig and someone with experience in welding on flanges. I have included a link to the flanges we carry to the right. You would also need to replace the idler hubs on the trailer(s) with hub and drum assemblies. The problem with that is the Harbor Freight trailers use uncommon bearings...
view full answer... - Replacement Hub Options For a Spindle With 1-1/4 Inner Bearing and 7/8 Outer BearingI have a recommendation as we do not have any hubs that will use the bearing combination you have. I recommend replacing your spindles with the BTR E-Z Lube Spindle # TRU27FR. This will upgrade you to a more commonly found spindle size that use the same Inner and Outer Bearing # L44649. You will be able to use the Easy Grease Trailer Idler Hub Assembly # AKIHUB-440-2-EZ-2K. Since the spindle and hub are easy lube you will be able to fill the hub with Grease # L11465 and a Grease Gun # L30416....
view full answer... - Electric Brake Kit For Two 2,200 lb Axles On Aluma TrailerSince you have two 2,200 lb trailer brakes you should get two of the Dexter Electric Trailer Brake Kits # K23-103-104-00. These are good for 10", 12" and 13" wheels. This kit requires a mounting flange bolt pattern of 4" x 4" and are 7 x 1-1/4 drum brakes. A 4" x 4" E-Z Lube Axle # 8-173-16UC3-EZ or standard axle hub # 8-173-16UC3 will work but make sure that your hubs use the # L44649 inner and outer bearing to make sure these hubs are correct for your Aluma Trailer. All the hardware is...
view full answer... - Adding a Brake Axle to a 48 Inch Wide Home Made Travel Trailer on Harbor Freight FrameWhat you could do is use an axleless system # A35RS545E which comes with everything except a brake controller. The only issue is that you would need to also replace the tires and wheels with something like # TA73RR since the kit has a 5 bolt pattern and your trailer has a 4 on 4 pattern. We don't have a straight axle with the proper spring hanger spacing for the trailer. But you could potentially use # T20BTR-6048 and have a professional welded cut off the spring seats and weld on new...

If you pull a hub off and find that both bearings are L44649 you can use # AKHD-545-2-EZ-2K if there are grease fittings at the ends...

For this assembly you will want to torque the lug nuts between 75 and 85 foot lbs according to the attached spec sheet. You will also want to use the Dexter Electric Trailer Brake Assembly - 7" - Left Hand # 23-47 and Right Hand # 23-48.

With this in mind, the Dexter E-Z Lube Trailer Hub and Drum Assembly # 8-173-16UC3-EZ is the correct hub and drum for the trailer. It features the 4 on 4 inch bolt pattern you are needing along with the E-Z Lube grease cap with plug and seal to allow for easy bearing maintenance. Since you will be changing out the hubs...

I have attached options for each setup below. ASR1200S04 - Dexter Hub/Drum part # 8-173-16UC3-EZ - Dexter Trailer Brakes part # 23-47-48 ASR1200S02 - Dexter Idler Hub part # 8-91-05UC1-EZ

With 2 of these you can have an axle welded up with 2 Spring Seats # TRSS175 in the dimensions you are needing. Then you will be able to attach the Brakes # AKEBRK-2 and Hub/Drums # 8-173-16UC3-EZ.

Ultimately you are correct that the most accurate way to determine the correct hub and drum assembly is to pull the hub and find the bearing and grease seal numbers or at least use a digital caliper to measure the spindle where they sit.

- Can You Add Trailer Brakes To A Trailer With 2200lb AxlesAbsolutely! If your auto-flex 2200 lb axle does not already have a 4-bolt brake mounting flange you would need to add one. Assuming that your axle is 1-3/4" diameter you would need the # 4-34. The brake mounting flange will need to be welded on by a professional as it needs to be welded perfectly square to the axle or you may experience abnormal tire wear or other braking issues. Next you will need to confirm the inner and outer bearings your current hubs use. You can do this by removing...
