Salt and water can ruin a hub fast, but this one’s made to handle it. The Dexter Trailer Idler Hub Assembly has a galvanized zinc coating tested to withstand 500 hours of salt spray exposure. That means it’s tough enough for marine use and frequent immersion without corroding or binding up. It’s a smart match for trailers that see regular water contact thanks to its true marine-grade build.
Everything you need comes in one box—inner and outer bearings (L44649, 1.063" inner diameter), races (L44610), grease seal (10-9, 1.5" inner diameter and 1.987" outer diameter), grease cap, and zinc-coated lug nuts. Each part is already matched to fit 2,200-lb idler axles with BTR spindles, so there’s no second guessing or extra parts run needed.
Each hub carries 1,100 lbs and fits wheels from 8" to 12". The solid construction and 1/2" wheel bolts provide dependable strength for small utility and marine trailers. The 5 on 4-1/2" bolt pattern keeps things standard, making wheel swaps simple when it’s time for fresh rubber or a spare.
Replacing old or damaged hubs doesn’t have to be complicated. This complete hub slides directly onto your spindle using the pre-installed races—no hammering or alignment guesswork required. It’s a direct solution when you’re refurbishing an older trailer or keeping a spare hub ready for roadside repairs, saving time and effort when it matters most.
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"

Very responsive would definitely order again!!
One hub on, one hub to go!! Really nice quality....from a great e-retailer!!
Kit was quality and functioned properly, no problems as of 1 year later.
Worked just fine, like everything else I have bought from you folks. Your product knowledge when needed is always helpful too.

Great products and prices. Very fast shipping. But best of all, incredible instructional videos.
This worked great on our boat trailer
Product as described attentive customer service
Hubs used on ssnowmobile trailer. Held up well through winter #1. Galv coating still looks good.
Order was reprocessed to be returned to sender because the wrong street was on the box. I had to go and make calls after calls to finally sto the return
When I called the guy on etrailers end was so rude on the phone telling me sure uts 3:30 in the afternoon I do t have time for this it's time for me to go hom and then hung up.
Purchased a hub assembly for a trailer and a wheel and rim. Excellent quality products and very rapid delivery. Very good product info on the website
After the first parts got lost in the mail e trailer expedited shipping to gut us new parts in a very timely manner. Parts worked great!
Fit perfectly, only had to buy a set of grease seals as my Hobie trailer had smaller hubs (1 1/4 vs the 1 1/2") that would not be compatible with the grease seals provided

Bought new hubs/bearings for my Shorelandr boat trailer. Ricky in customer service was most patient helping me pick the proper parts. Got the hubs Monday am, installed them Monday afternoon, piece of cake!
I received my hubs last week, shipping was nice and fast, and I installed them over the weekend. Kits were complete and everything fit perfectly. The only negative comment I would make is that the hubs do not look like they do in the video or picture. Instead of a "round" shape hub, they are a "star" shape hub, which made me think I had received the wrong ones. Once I pulled off my old ones and checked all the measurements I realized the difference between the two was purely cosmetic.
Very happy!
These are very well constructed and etrailer does a good job at putting together a kit that contains everything you need. You will have to keep though your old washer, nut, and pin.
Make sure you are ordering not only the right size of bearings, but also the grease seal. Some not-so-standard hubs have mismatched seal sizes. Measure your spindle and your seal seat. If your spindle is larger in diameter than the 1” (1.058”) this is the right kit for you. But also measure your seal seat. This kit shipped with a seal that fits a seat that’s 1.5” in diameter. If
Yours is closer to 1 ¼” you are going to need a different seal. etrailer quickly rushed out those for me!
Just what I needed to replace the original worn out hubs on my small trailer. Parts arrived quickly in great condition and were a direct replacement. These hubs are actually better than the original hubs, they are galvanized not painted and will better protect from rusting, they also came with 1/2-20 threaded studs compared with threaded bolts on the original hubs. The idler hubs also came with all the required components to repair my small trailer.
I needed a wheel hub for a jet ski trailer, but wasn’t getting anywhere with determining the correct fit. Joshua T. helped me find the right one. He was extremely personable, patient, and above all- knowledgeable about his products. A pleasure to deal with, and I will definitely use E-Trailer for all my trailer parts needs.
I have not yet installed them but have unpacked and took measurements. The only issue I have is the grease seal ID is .25 to large but that is most likely my fault during the order, I have the right size grease seals coming.
The hub is solid and the bearings fit real nice, no slop. This is for a boat trailer which goes back and forth to a very rural camp so it gets bounced around a lot, time will tell how these hold up. The original hub and bearings are ok and will be my field spare should I need it, slip one hub off and the other on, tighten and go. I like the stud with lug nut to hold the rim rather than original bolt into the hub, easier for tire mounting and I can put a locking lug nut on as well, personal preference.
This seemed to be the most cost effective means, all one package, just watch the size of the individual parts to make sure you get all the parts the correct size.
etrailer.com packed the parts well, nothing flopping around or damaged.
No complaints, now the dirty part, replacing the old with new.

Still on the trailer and working out well. I have put some hard miles on them and they seem to be holding up. Just shot some grease in them before the next trip.
