When a bearing goes out on the road, you don’t want to dig through parts. This Redline hub assembly comes complete with everything you need—bearings, races, grease seal, grease cap, wheel bolts, and lug nuts already included. It fits 2,000-lb axles with BT8 spindles and is built from sturdy iron for dependable durability. With a full kit like this on hand, roadside repairs or trailer restorations go a lot smoother.
Finding the right hub size can be tricky when working on older or custom trailers. This idler hub is made for 10" to 12" wheels and uses a common 5 on 4-1/2" bolt pattern with 1/2" wheel bolts. The flange diameter of the grease cap is 1.986", making it simple to match up with standard bearing protectors or dust caps. Each hub has a 1,000-lb capacity for light-duty towing setups and small trailers.
Good alignment starts at the bearings. Both the inner and outer bearings are L44643 with a 1" inner diameter, and their races—L44610—are already pressed in at the factory for perfect seating. The included double-lip grease seal (part 34823) measures 1.249" inner diameter and 1.983" outer diameter to keep lubricant where it belongs. You get consistent performance without the guesswork of pressing races yourself.
This hub’s solid iron build gives it reliable strength for constant towing duty. Whether you’re refurbishing an old trailer or adding a spare for emergencies, it’s designed to keep rolling mile after mile without flexing or wearing unevenly. Paired with proper greasing and torque on the lug nuts, it’s a long-term fix that holds up under regular use.
Ensuring your wheel or hub has the correct bolt pattern is essential for a proper fit. The following diagrams show how to measure both even and odd-numbered bolt patterns accurately.
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
fit perfect,
great website I easily found what I needed,
seems well made,
the outside dust cover was hard to install (I had to fiddle with it)
I am just starting on a restoration of a 40 plus year old motorcycle sidecar and the hub and wheel that I ordered are perfect for this project. I will try to send pictures on completion, probably a few months out.
Shipping was fast and install was easy...your measurement guide was very helpful to figure out my spindle size and lug stud spacing for my wheel. Thanks
Great price, fast shipping, and customer service is professional. I will continue buying from etrailer. Thanks for your business.
perfect fit thank you for great product
Perfect fit. Bad old trailer bearings? Buy the complete hub!
Not only is the product exactly what we needed (the dust caps are a little on the lightweight side) but Matthew was extremely helpful in getting me the parts I needed to fix my trailer!
Hubs not made by dexter and not made in US. No reason to pay extra for these over other Chinese hubs. Would have returned but etrailer was slow to ship and I was leaving for a trip and couldn't wait.
I was told the hub I ordered would fit my trailer but when I received it the set up was for an axle with a 1” diameter axle and not a 1.063” axle which I have. I had to order another hub.
Put on trailer brand new again hubs bearings all good fast shipping will deal with you again thanks
I initially ordered a pair of hubs from another online retailer That I has used prior and whom had mine "in stock". They didn't. After 5 days of no shipping info, they notified me they were back ordered. I cancelled the order.
I ordered a pair of these hubs from etrailer.com on 6/2, George notified me on 6/3 that they shipped and I received them on 6/6. That's customer service.
Price, availability and delivery. Every online retailer should strive for this level of attention..
Hubs went on without any trouble. Only tricky part was to get the caps seated into the hub to trap the grease. Haven't used the trailer yet, but don't anticipate any problems. Shipping was awesome. I ordered with standard shipping and the box was on my porch the next afternoon.
The hub I ordered for my trailer worked perfectly!!!!!! The customer service is unreal, from fast shipping to constant checks(personal emails) to see if item had arrvied on time, truly a professional company that puts their customers above all. I never write reviews put this company definetly earned it, Thanks and I will be back!!!
Ordered two hubs, only one arrived. Second tracking number says it was never picked up. Now I have to wait 8 days for an investigation before I can get a replacement part. Upgraded the shipping so I could receive and work on trailer during the holiday break. No blame, just stating what happened.
I have ordered from e-trailer twice. Both times they provide excellent service! Parts arrived amazingly fast!! One order had a damaged part, I called and got a very nice sales rep. Parts were replaced FREE. I will deffinatly order from them again. I ordered hubs, wheel and tires, and light kit for my boat trailer. All parts are good Quality.
These hubs worked great. I had to add the spindle nut washers to get good engagement between the spindle nut and cotter pin. I would definitely buy these again.
I wanted to change from four lug wheels and tires to five lug type on my boat trailer. Towed trailer,loaded with fishing gear,fuel tanks, extra motor. and batteries from central Pennsylvania to Fort Peck, Montana and back. The trip was uneventful. Other than the fishing....it was GREAT!
Your new hubs made my trip successful.
Install was easy, I just wish it came with a cotter pin. I had to run to HomeDepot.
Had to resnug the castle nuts, but ID was perfect. No noticeable wobble in the part, and held 1250lbs like it was supposed to. Part was delivered very quickly, which was much appreciated! I’ll buy from them again.
exactly what I ordered
Good quality hubs and very good service from eTrailer.
The hub was very easy to install. The only problem I had was installing the wheel bearing hubs. It took many tries to get them on.
There was a problem with the initial order I received and it was promptly handled by the polite and helpful customer assistant. These parts worked great for a single bike takedown trailer.
I have ordered 2 trailer hitches and wiring hook ups, all have been great. Now just received replacement hubs and bearing kits for the boat trailer,awesome one stop shop. Will order in the future. Thanks etrailer for quick shipping.
Received the hubs in just a couple of days. They fit perfectly and it's so helpful to the bearings pre-greased. They came with various parts that I really didn't need but was nice to have them just in case. Thank you for your excellent service.
