Salt, spray, and moisture can destroy a standard hub in no time. This DeeMaxx galvanized idler hub is built for it. The marine-grade steel construction and galvanized finish hold up against rust and corrosion, making it ideal for boat or snowmobile trailers that see wet or salty conditions. You get the confidence of a hub that’s designed to stay strong trip after trip.
Matching bearings and seals is simple with this hub’s clear specs. It’s made for 6,000-lb axles with #42 spindles and uses inner bearing 25580 (1.750" ID) and outer bearing 15123 (1.250" ID). The pre-installed races—25520 inside and 15245 outside—save time during setup and ensure everything mates correctly with your spindle and bearings.
Whether you’re running an idler axle or planning to add disc brakes later, this hub fits right in. It can be used by itself or paired with a 12" slip-on rotor for disc brake setups. The 1/2"-20 x 2-1/2" wheel studs are long enough to handle an over-the-hub brake rotor or a thick custom wheel face without short threads or spacing issues.
Each hub carries a 3,000-lb rating, giving you solid support and balance across a tandem setup. It’s designed to handle steady towing without flexing under load. You’ll appreciate the tight fit and smooth spin that comes from well-machined races and solid stud alignment—ready to roll mile after mile.
You can finish the hub your way using the matching grease seal (GS-2125DL) and your choice of standard or E-Z Lube style grease caps like #F001520 or #DC250L-DCRP. That flexibility makes it easy to keep your bearings sealed up tight against dirt and water while fitting the maintenance style you prefer.
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"

Hi everybody, Andy here with etrailer.com. Let's take a look at this DeeMaxx Galvanized Trailer Idler Hub. This marine grade trailer hub assembly is going to fit your 6,000-pound trailer idler axle with a Number 42 spindle, and this long, the long wheel studs are going to let you pair this with an over-the-hub brake rotor for disc brake applications or a custom wheel with a thick mounting face. This does feature a galvanized steel construction that's going to be durable and corrosion resistant. So this is going to be great for use on a boat or a snowmobile trailer. And this has a bolt pattern of six on five and a half inches.
And to measure the bolt hole diameter on a pattern with an even number of bolts, as you can see you're just going to simply measure from the center of one bolt hole to the center of the other bolt hole directly across, and that gives you your bolt hole diameter of five and a half inches. And some other information that you're going to find helpful I have there on your screen. The dimensions of the wheel studs, it's a half an inch in diameter and two and a half inches long. And this has a weight capacity of 3,000 pounds. So when this one is matched with the one on the other side of the axle, that's where it's going to meet your 6,000-pound axle capacity.
And this does include the races. They are pre-installed as you can see here. And the bearings, the grease seal, and the grease cap are sold separately. And just to give you that information on the bearings first, the inner bearing is 25580. The outer bearing number is 15123.
And the races again, that are pre-installed, the inner race number is 25520, and the outer race is 15245. And then the grease seal, you'll need to pick that up as well. And the grease seal number you will need is GSS-2125DL. Now this hub weighs about a little over seven pounds and that's going to conclude our look today. I do hope that it was helpful for you.
Again, my name is Andy. Thank you for joining me.

Very quick delivery…….Great product!!!
Nice product at a good price shipped expeditiously for free.
Deliverd the next day. Good quality pro duct.
Fast service and exactly what I needed
Part of my DE46AR upgrade.
Received in good condition
Will install them in a few weeks
Very pleased with the product
I installed new hubs because I ordered the wrong Hydra Star brake system (rotors only), the hubs assembled without issues. I also installed the Comfort Ride Slipper System when I did the Hydra Star brakes.
I have around 250 miles on this setup traveling through SE Kansas, SW Missouri and NW Arkansas. The road from Joplin to Eureka Springs AR was a hair raising experience, 2 lane 15 to 35 mph curves with the side of the mountain 3 feet from the edge of the road. I was glad to have the new hydraulic brake system, I would not tow another camper without them.
I know this review covers more than the hubs but everything worked well. I would purchase everything again. I would also like to mention shipping, I ordered them Friday at 4pm and received on Tuesday. Thanks
Perfect, cheap enough to not bother cleaning up the old ones plus a galvanized finish
Good, little bit late, but that's good.
Well you'll be able to log on to the ground
Great service and knowledgeable Employe es.
Perfect fit
Good value in galvanized hubs.
Good price and quality not sacrificed.
Very good trailer hubs use for salt water and disc brake install. Happy with this hubs
Although galvanized, I sprayed the hubs with galvanizing paint (2 coats) to act as a paint primer. Then sprayed with black paint (2 coats). No rust and paint is tightly adhered one year later. I also purchased stainless grease caps at installation because the standard caps always rust. Fit, form, function, and finish worked great for my saltwater boat trailer.

Follow-up 2-year post after my 1-year post. Paint is still tightly adhered. Hubs are working just fine. Grease does ease out the grease caps, but I think that is expected for hubs with grease fittings.
