Features to know about
Heavy-Duty Stopping Power: Fits 5,200-lb to 7,000-lb Axles
This Dexter hub-and-drum assembly gives you solid braking performance you can count on. Built for 5,200-lb to 7,000-lb axles with #42 spindles, it’s made from sturdy iron and provides the surface area your brake shoes need for strong, consistent grip. The 12" diameter x 2" wide drum works with 12" electric or hydraulic brakes, and each hub carries a 3,500-lb weight capacity for balanced strength across your setup.
Direct-Fit Bearings and Seal: 25580 / 14125A Combination
When you’re swapping out old or worn hubs, having the right bearing setup makes all the difference. This assembly uses the common heavy-duty pair—inner bearing 25580 (1.75" inner diameter) and outer bearing 14125A (1.25" inner diameter)—along with matching races and a GS-2250DL grease seal (2.25" I.D. / 3.376" O.D.). That means quick, confident installation on standard #42 spindles without hunting down extra parts.
All-In-One Hardware Kit: Ready to Assemble and Roll
Everything you need to mount and finish the job is in the box. Each assembly includes the bearings, races, grease seal, grease cap, wheel bolts, and 1/2"-diameter lug nuts. Just pack it with your preferred grease, slide it on, and torque it down. The 8 on 6-1/2" bolt pattern matches common heavy-duty trailer wheels with pilot holes 4-3/4" or larger, so you get straightforward fitment and secure wheel seating.
Built to Last: Durable Iron Drum for Long Service Life
Dexter’s iron construction gives this hub and drum lasting reliability under load and heat. The machining keeps the drum round and true, helping your brakes stay smooth and even mile after mile. It’s a practical, proven design for anyone refreshing, upgrading, or keeping a dependable trailer rolling.

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"

Item was shipped and delivered very quickly. Shipping container was damaged, but items were fine. Top quality product at a Great Price. 4 stars because shipping container was to big for heavy drums. Drums were able to move freely. Corner of box had a large tear in it (open). Nothing fell out of container, drums had some rub wear marks. Thanks for the fast shipment and quality product.

- How to Pick Out Brakes for 3,500 lb Boat Trailer with Tandem AxlesInstalling brakes on a trailer really isn't too bad. The install is pretty basic and a DIYer like yourself wouldn't have a problem at all. To determine the parts you need though we need to for sure know what axles/spindles you have so that we pick out the right parts. I attached a couple guides for that down below for you to check out. There are a lot of boat trailers that have great results with electric drum brakes so if that's a route you are interested in that's what I would recommend...

- Recommended Electric Brake Assemblies and Hub Drums for a 26ft Gooseneck TrailerIf your brake assemblies mount on a plate using 5 bolts, you most likely would be looking for a 12 inch diameter brake assembly like part # AKEBRK-6R and # AKEBRK-6L, but you could verify this by measuring directly across the center of your drum or the brake assembly. To recommend the correct hub drum for your application, I would need to know your current hub bolt pattern, as well as the bearings it uses. In order to determine your hub drum bolt pattern, you would need to measure center...
view full answer... - Are Dexter 23-112-113 Brakes and Dexter hub 42866UC3 Compatible? Hey Jesse, great question and you’re absolutely right to double check this before putting anything together. Yes, the part # 23-112-113 brake assemblies and the part # 42866UC3 hub and drum are compatible with each other. They’re both built around the same 12 inch by 2 inch brake size, so from a brake to hub standpoint, they’re designed to work together. Where you’ll want to pause and confirm is the bearings inside the hub match your spindle, since that’s what really determines whether...
view full answer... - Hub and Drum Assembly for 1 1/4 inch by 3/4 inch Axle 1 1/4" by 3/4" axles use item # LM11949 as an inner bearing and item # LM67048 outer bearing. I recommend the Redline Trailer Hub Assembly item # AH15450ECOMP. These hubs are for agricultural applications and are rated for 3,000 lbs axles and have a 4 on 5 bolt pattern. This kit is sold individually so you will need to purchase two.
view full answer... - Parts Needed To Convert M1101 Military Trailer To Electric Drum BrakesCurrently Dexter only offers either the Self-Adjusting Brakes # 23-464-465 or Brakes With Parking Brake # 23-112-113 which will fit your 1997 M1101 trailer. Both of these are sets of brakes for the left and right while the Drum # 42866UC3 is offered as a single unit so you will need to order 2 of the drums. The drum will include the bearings, races, grease seal, cap and lug nuts for a 8 on 6-1/2" bolt pattern. You will likely need the Dexter Breakaway and Parking Kit # T2385200 should...
view full answer... - Is There Standard Hub/Drum Available for Replacing Dexter 8-222Hey Brian, I did some research on your Dexter 8-222 Hub and was able to find the inner and outer bearing numbers as well as the grease seal used. It looks like this particular hub was designed for mobile homes and these, for the most part, have more unique bearings and bolt patterns because they are technically manufactured for one time use only and not meant to be altered or replaced. Because of this, there is unfortunately not a 6 on 5-1/2 inch hub available that will be compatible with...
view full answer... - What Bearings Do I Need for my CZ Model CZ18KT TrailerThanks for your question, Gordon. I'm more than happy to help find the right Timken bearings for you, however we don't have a way to know what bearings you need based off the trailer that you have. Depending on what hubs you have on the trailer, there may be some numbers on them that we can cross reference. I included a picture below of a Dexter hub as an example. Even if you don't have dexter hubs, there may be a number on there that I can still search for. Let me know know when you can!
view full answer... - Solution for Replacing Dexter 8-222 Trailer Hubs and Bearings The Dexter 8-222 model hubs currently on your trailer are designed primarily for mobile home use, and these types of hubs typically use unique bearing combinations that make it really difficult to find full replacement assemblies. Mobile home parts like these are really only manufactured for one time use so replacements aren't usually available. The only replacement parts I can offer for your existing setup are the bearings and seal, which can be found with part # L68149 for the inner...
view full answer... - Trailer Hub Recommendation for a Number 42 SpindleBased on the dimensions you listed it sounds like you have a number 42 spindle. All you need to do now is verify that the surface of the spindle where the seal rides is 2.24 inches. If so then the trailer hub like the part # 42866UC3 would fit and work well. It will require a trailer rim with an 8 6-1/2 inch bolt pattern though like part # TA26FR.
view full answer... - Correct Replacement Wheel Studs for a Dexter Trailer Hub and Dumb Assembly for 5,200lb AxlesIt sounds like you have the Dexter Trailer Hub and Drum Assembly # 42866UC3 in which you'd just need the Trailer Hub Wheel Stud # 7-122 for a replacement.

It has a specified inside diameter of 1.938-inches and an outside diameter of 2.523-inches. The nearest match we offer is the Redline part # 10-40 which is a single-lip seal that has this exact inside diameter and an outside diameter of 2.510-inches.

view full answer... - If a Hub Fits 5K to 7K Axles, What Makes a 7K Axle More Heavy Duty than a 5K AxleA hub such as # 42866UC3 fits on the spindle which is welded to the axle and spindles can have different capacities as well. The camber or bow of an axle, its length, the quality of materials, the diameter, and many other factors go into its capacity rating. So in a way, yes, it is all in the axle tube, that and other factors as mentioned above. Ideally you will get parts that are rated the same as the axle. Otherwise you can end up with a poor ride or tracking problems. Adding higher...

Other than that, # 42866UC3-EZ and # 42866UC3 are the same.

If you are looking for replacement hub and drum assembly parts, I can try tell help you find them if you know the bearing numbers or spindle measurements on your trailer, but unfortunately I cannot guarantee that your axle has the same wall thickness as a standard 3,500...

In order to determine the correct hub and drum for your 7k axle(s) you will need to know what bearings and grease seal you have. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be...
view full answer... - Will Hub with 25580 and 14125A Bearings Fit in Place of a Hub with 25580 and LM67048 BearingsYes, you can use a hub and drum assembly that uses outer bearing # 14125A. It has the same inner diameter as the # LM67048 bearing but with a different outer diameter. Hub and drum assembly # 42866UC3 will work if you need an 8 on 6-1/2 bolt pattern (which is the only option for that particular bearing combination).
view full answer... - Correct Braking Assemblies and Hubs/Drums for 1999 Pace American Cargo TrailerThe correct braking assemblies and hubs/drums for a 1999 Pace American Cargo Trailer are as follows: Dexter Electric Trailer Brake Kit part # 23-180-181 Dexter Trailer Hub and Drum Assembly part # 8-219-4UC3 (2.125") or part # 42866UC3 (2.250") If you don't know what grease seal you need (requires measuring) as it could be either 2.125" or 2.250", you can simply purchase either hub/drum and the extra seal, part # GS-2250DL or part # GS-2125DL so you're covered either way.
view full answer... - New 7K Trailer Axle to Replace a Lippert 6K Trailer AxleWe have 7K options but they not a traditional straight axle. They are more like torsion axles that have their own built-in suspension and do not require an axle beam between the 2 sides. This design would then provide independent suspension! The most basic option is # TASR7KS01. It has brake mounting flanges but no hubs or drums. This allows you to select the hubs/drums and brakes you want. They do have the grease fitting for EZ lube hubs but you don't have to use EZ lube hubs. You can...

If you have a leaf spring axle then what you are going to want to do is measure the diameter of the axle tube. Once you measure the axle tube you can then use the chart below to give you an idea of what the weight capacity is. If you have a torsion axle then your next best option would be to...
