Features to know about

Built to Handle Heavy Loads Without Brake Fade: Vented 13" Rotor for 8,000 lb Axles

When you’re hauling big weight, brake heat can build fast. This DeeMaxx 13" hub-and-rotor assembly is built for 8,000 lb axles and uses a vented rotor design that keeps air flowing through to shed heat. That means less chance of warping or fade on long pulls and more confident stopping when you need it most. Precision machining keeps the rotor running true, so every stop feels smooth and steady.

Rust and Corrosion Protection That Holds Up in Harsh Conditions: Maxx Coating with 1,000-Hour Salt Spray Rating

Water, road grime, and salt can eat through standard metal fast. This cast iron hub-and-rotor is finished with DeeMaxx’s marine-grade Maxx coating that’s been tested for over 1,000 hours of salt-spray resistance. Drain holes in the hat section let water escape quickly instead of pooling inside, cutting down on corrosion whether you’re running in rain or snow.

Simpler Installs That Stay Clean: One-Piece Hub-and-Rotor Assembly with Pressed Races

Swapping hubs shouldn’t mean juggling loose parts. The DeeMaxx DE25KR comes as a single cast piece with both inner and outer races already pressed in. There’s no gap between hub and rotor for grit or moisture to sneak in, making it easier to install cleanly whether you’re upgrading from drums or replacing worn discs.

Strong, Smooth Performance for Long Hauls: Cast Iron Build with Balanced Design

Uneven brakes or vibration can turn any trip into a hassle. This machined cast iron assembly is factory balanced to keep rotation true and minimize shimmy at speed. The material delivers the right friction coefficient for steady braking power while standing up to heavy use over the miles.

Straightforward Fit for Common Spindles: Standard Grease Hub with 5/8" Studs

This unit is a standard grease hub that fits setups using inner bearing #25580 and outer bearing #02475. It’s designed for wheels between 16" and 17-1/2", with an 8 on 6-1/2" bolt pattern and 5/8" studs—making it an easy match for many standard components without guesswork.

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.

Center to Center
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).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Video Transcript for Review of DeeMaxx Trailer Hubs and Drums - 13 Inch Hub And Rotor Assembly 8K Trailer Axle - DE25KR

Hi everybody. Andy here with etrailer. Let's take a quick look at this DeeMaxx 13" hub-and-rotor assembly for your 8,000-pound trailer axles. Now, if you're looking to upgrade from drum to disc brakes, this hub-and-rotor assembly is gonna make the switch pretty simple for you. This single-piece design means installation is gonna be quick and straightforward. No need to worry about contaminants sneaking between the hub and rotor.

Everything is machined from cast iron and precision balanced for a smooth, reliable ride. And because of the vented design, it's going to dissipate heat efficiently, helping to prevent warping or heat-related wear. And if you notice here in the hat section that even has drainage holes that let water escape easily, reducing the risk of corrosion. And with the durable Maxx coating, you're gonna get excellent rust resistance, whether you're driving in fresh water or salt water environments. In fact, this has been tested to withstand over 1000 hours of salt spray.

So this is going to include 5/8" wheel bolts and standard races that are already pressed in so you're gonna be ready to go. Again, this is going to be designed for your 8,000-pound trailer axles. It's going to fit wheel sizes from 16" to 17 1/2". And this bolt pattern is 8 on 6 1/2". And this is a 13-inch outer diameter hub-and-rotor assembly.

Now inside, you will need bearings and a grease seal. Those bearings and grease seal are not included with this, but on your screen, I am including the bearing and seal information there for you. And you can refer back to this product page if you need that information again after this video. But we do carry those items, the bearings and the seal, here at etrailer if you need them. If you happen to have any other questions, whether it's about this assembly or anything else that we carry here at etrailer, don't hesitate to reach out to us.

We wanna make sure that you're getting exactly what you need. Well, again, my name is Andy. Thank you for joining me.

Product looks good and delivery fast but they need to pack better. You have 3 heavy hubs in a cardboard board with little re enforcing. When I opened box, one of the hub boxes had opened and it was partially hanging out of the main box. No obvious damage but that was just due to luck
by:
These items did not fit, it was supposed to be cross referenced. It also did not show up the next day as promised. I only live 20 minutes from the place I could have drove up there and right a way realized they were the wrong parts. I think your missing an opportunity from your local customers, even a drop off pickup window would have saved me a lot of hassle. I will say the quality of products look good and the staff is very friendly.
by:
Good price and fast shipping.
by:
My DeeMaxx was a great direct replacement for the original Dexter rotor. Thanks for the help in choosing it E Trailer.
Way up in Kenai Alaska we do not have parts in a store shelf.

Tristan did a great job getting my order together and shipped! Everything was correct when it arrived.

Love to hear that, Darryl! Have you tacked installing the brakes yet?

by:
I’ve operated my boat trailer without any subsequent issues for a year. Thank you for providing a single source for all the needed parts to replace the component on my torsion axle trailer.
by:
ITEMS WERE EASY TO ORDER, AND PARTS ARRIVED ON TIME
by:
Fits and works perfectly
by:
Slight “burr” on outboard race. Not enough for return. Will use race that came in bearing pack.
Would guess it happened during factory race installation.
Hub itself looks great.

Hey, Michael. I'm really sorry to hear about the pre-installed race. I'm going to have a replacement shipped out to you since you used the one that came with the # BK2-100 you ordered. That way you still have a back up if you need it.

by:
The product is of high quality and the bearing cups were already installed. The support staff Kim R. and Ashley are excellent to work with and the same can be said of their company. When a hub was lost in transit another hub was shipped immediately when the required wait time expired. This company has very high customer core values and I would highly recommend them for trailer parts.
by:
Very good quality, was in perfect condition on arrival, performs as the OEM hub did.

as described, easy to assemble, super-fast shipping
