Frequent dunking in saltwater can destroy standard hubs in no time, but this one’s built to last. The galvanized finish on the Dexter 12" x 2" hub-and-drum assembly has a 500-hour salt spray rating, giving it real staying power in marine environments. It’s a marine-grade setup designed for both electric and hydraulic brakes, perfect for trailers that see regular launches and recoveries.
When a bearing fails or a hub needs to be swapped fast, having everything ready in one package makes the job simple. This assembly comes complete with inner bearing (25580), outer bearing (15123), both matching races (25520 and 15245), grease seal GS-2250DL, grease cap, 1/2"-diameter wheel bolts, and zinc-coated lug nuts. Each piece fits together cleanly so you can install it and get back on the road or back to the water without hunting for extra parts.
Good brakes start with a solid hub and drum. The 12" diameter x 2" wide drum provides the right surface area for consistent shoe contact and smooth braking performance, whether in electric or hydraulic systems. The assembly supports up to 3,000 lbs per hub, giving you dependable stopping power when you’re hauling heavy loads or towing long distances.
Salt spray, road grime, and moisture can eat through bare metal fast, but Dexter’s galvanized coating keeps rust at bay. Every GAL-DEX hub goes through a 5-percent salt solution test for 500 hours of continuous exposure, proving it can stand up to freshwater and saltwater alike. That means less corrosion and a longer-lasting hub you can count on season after season.
If you’re running a typical 6-bolt wheel setup, this hub and drum is ready to fit. It mounts on #42 spindles, works with wheel sizes from 14-1/2" to 16-1/2", and has a grease cap flange diameter of 2.446". Built for reliability and ease of use, it’s a practical replacement or spare that fits right and performs well under load.
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"

As always... just what I ordered in a timely fashion.
Ordered these at same time as ordering new brakes. Went together with no problems, fit just like originals
I got the parts as stated Direct bolt on no issues. I found the web site to be helpful. This is my new trailer parts store.
Perfect replacement for my old worn out Hub/Drum. I went with the galvanized becasue of use in saltwater.
Thanks E-Trailer.
So far so good! Wish it would have come with new castle nut and washer. Fast delivery!
I used these on my salt water boat trailer. The product works very well and have stood up to the salt water quite well.
I am happy with the results and ease of use.
Both drums had rust spots in the same location, like they were sitting somewhere with water in them. Used some 200 grit sandpaper to remove the rust be surface of drums still marred.
These brake hubs state made in USA, but the bearings are clearly stamped with China. I specifically asked the rep about the bearings & they told me they’d be made in USA. Not too happy with Etrailer customer service. When I called to inquire about the Chinese Bearings they said there’s nothing we can do, as Drexler controls the packaging for the Brake Hub kit.
Excellent resources to help determine the exact parts I needed for my trailer project. Great product descriptions and videos. Competive prices and quick shipping! Thank you very much!
I'm just getting around to installing my drums, thanks for promptly getting them to me, they look great!
I'm wondering if this product has the free backing feature or if I need to manually lock out the brakes when backing up. Any information is appreciated.
Bought the galvanized drum brakes for a 6000# boat trailer used strictly in salt water. With rinse off after use they seem to be holding up pretty good.
I would highly recommend etrailer if they have what you need. These people really care about filling your order properly and followup with anything you order from them. They assume nothing!
This is a class AAA business to do business with.
Decided to try a galvanized drum for my boat trailer. Hopefully lasts better with no rust. The wheel studs on these drums are longer than the non galvanized version for some reason.
Stripping down a 16 year old 21 ft. salt water use trailer - from end to end. The folks @ etrailer were very knowledgeable, and helpful in my decision making. From placing the order, to tracking the order, to the way the items were packed for transit. Other distributors could learn from these people; in regards to customer service, following up, both office and warehouse. Unloaded the products last night, nothing short, all quality in regards to their products, with great pricing. The installation videos are a big bonus, and something I'll be taking advantage of, during the restoration. Will follow up with picture, (before and after) when I'm done
The drums worked out fine, but the coating is just the spray-on type and not the electro-plated type so it wears and flakes off. Not worth the extra price over black painted hubs. Also, the paint seems to be making the brakes take a long time to wear in. They painted on the brake surface, which I should've sanded off.
I ordered two hub assemblies with the bearing races installed, and upon receiving them, found a couple of races pitted and rusted; as well as one lug nut missing (The reason for the four stars is for quality control). Understandably, E-trailer simply asked for a few pictures of the races; and sent replacements out; no questions asked. Can't argue with service like that. They are a company that will make every effort to earn your business and repeat business.
Everything purchased worked exactly as expected and continues to do the job I needed of them. I have and will continue to purchase all my trailer products from E-Trailer...
Cheap junk. One of the hubs was not properly coated. Will not recommend this to anybody. Cheap junk from China. Photos will be attached.
We had a break down on Saturday when we picked our boat up from storage. Went online and ordered the necessary parts to repair the trailer and forgot about it for a couple hours. Etrailer called to notify us that the selected parts would not arrive as hoped based on the shipping I had chosen. They went out of their way to locate the suitable parts and verify that they would arrive by the time I needed them so we could get the trailer repaired and back on the road. Thank you Etrailer for the excellent customer service!!! I look forward to my next order with you!
Shipping was pretty fast and packaging nice and secure. The drums and brake backing assembly were a breeze to install without instructions. I was a bit surprised though that the back kit did not come with 4 new bolts to secure onto the flange. I used the old ones. The drum kit comes with new lug nuts though. I have no real complaints, I would definitely use etrailer again. Excellent pricing and quality. I installed these brakes the next day after receiving them. I used marine grease from autozone to pack the new bearings. The brakes are bled and adjusted as per the sticker on the kit...adjust til you cannot turn by hand and 10 clicks out. All that's left is to test drive it.
Product has held up remarkably; I trailer only so there are weekly drops for the boat.
Last year was lighter then normally but all in all better then I though they would last.
I replaced the entire triple axle suspension on my 5 wheel with your products. Everything went well and I’ve had no problems with the updates.
Product is good quality, it was just what I needed, And fast shipping would definitely order from again and recommend to family and friends.
this is the best prodact
