This hub is made for real work. It fits 6,000-lb axles with #42 spindles and carries up to 3,000 lbs per hub. The sturdy iron construction gives it the strength to keep rolling under heavy loads day after day. When you’re hauling serious weight, you need a hub that’s built for it, and this one’s ready to take it.
No need to track down separate components. This Dexter idler hub assembly comes with the inner bearing (25580), outer bearing (15123), both matching races (25520 and 15245), a 10-36 grease seal, grease cap, wheel bolts, and lug nuts already included. It’s a full setup that lets you swap out your hub without digging for extra parts or hardware.
The hub uses a 6 on 5-1/2" bolt pattern with 1/2" wheel bolts and a grease cap flange diameter of 2.44". It fits wheel sizes from 16" up to 18-1/2". Everything matches standard hardware and wheel dimensions, which keeps installation simple and ensures replacement parts are easy to identify down the road.
The included bearing and race set is precision-matched for smooth towing. The inner bearing (25580) has a 1.75" inner diameter, while the outer bearing (15123) measures 1.25". The grease seal has a 2.25" inner diameter and 3.376" outer diameter to keep the grease where it belongs. With these exact specs, the hub seats perfectly on your spindle and holds up through long miles of use.
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"

Ratings & Reviews
In building two tear drop trailers (see attached picture) and do to a miss measurement I ended up with two axles without hubs. (another story!) So I decided to order hub and start making a utility trailer. I enjoy etrailer's website. It is very helpful in selecting the right trailer parts. Delivery was good but the packaging was poor. The bearing, seal, lug nuts and cap are all in one bag taped to the heavy hub. One of the seal were bent but the rubber part looked OK, so I straighten it the best I could and install it anyway. I did not want to go through the hassle of returning it for a new one.
IL N Y AVAIT PAS DE BEARING NI NUT DE ROUE , POURTANT SUR LE DESSIN IL EN A. [There was no wheel bearing or nut included, even though the diagram shows them.]
Awesome stuff. Between etrailer & Dexter we found a perfect idler hub replacement to go from demountable rims to rims w/lug nuts.
All I need now are rims & tires.
The young lady was earnestly working to resolve my needs. I would never hesitate to work with this team for all my trailer needs.
No grease cap or zerk to replace the one that came off the old hub. No way to grease other than removing the cap everytime. Not ideal for a marine trailer application. Got to find a different cap now.
ETrailer staff was able to find a hub to fit a very old spindle from a farm buggy we pull by tractor for kids to ride. They were able to match bearing sizes and sell odd size grease seal. Old tires, wheels and hubs were shot. A friend gave 4 jeep wheels to complete the job making a cool update.
What a fast turn around
I've not have a chance to use them.

High quality stuff, really impressed

Product as expected, delivery sooner than expected, overall very good. Replaced old hubs on moblie home axles. Very easy to do. Great service.
Always my go to for trailer parts.
PACKING IN BOX WAS A LITTLE LITE BUT PARTS WERE OK
Excellent! Works fantastic!
I used 42655UC1 hubs on mobile home axles just required different size seal to fit spindle, great product & you guys were very helpful with helping find a hub that would fit,very pleased with this product and service.
Great service and fast shipping - Ricky was a big help making sure that everything fit together - thanks a lot!
Good ExperieneWebsite laid out good, when ordering, it showed me what products went together instead of searching to find out like which hub goes to what axle and vise versa. Fast shipping and good products. Recommend them to anyone and everyone looking for trailer parts.
Pleasantly surprised that it came with bearings, seals, races, and lug nuts
Package was damaged and white powder or something on the hubs and bearings
Couldnt be happier with these hubs! First one I pulled out of the box, I just verified that the races were seated, and installed after packing the bearings. One hub out of the four had a damaged bearing and seal, but it was due to packing. No biggie, was able to "coerce" the bearing and seal to look "normal". Had all four corners done and back on the road in less than 4 hours, which included uninstall of old hubs, cleaning, packing and installing new parts. Quick shipping as well. eTrailer is a great place to shop!
