Corrosion Resistance for Marine Use

This trailer hub assembly has a zinc coating that resists corrosion, making it ideal for use on your boat or snowmobile trailer. All GAL-DEX hubs undergo a test in which they are sprayed with a 5-percent salt solution to determine corrosion resistance over time. These products are able to withstand 500 hours of constant exposure to the saltwater mist. This 500-hour salt spray rating indicates that a product is not only durable enough to last in freshwater environments, but it can also be used on trailers that come into contact with saltwater.


Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Average Customer Rating:  4.8 out of 5 stars   (25 Customer Reviews)

Galvanized idler hub assembly is great for marine use. Trailer hub fits 2,200-lb idler axles with BTR spindles. Inner bearing (L44649) and race, outer bearing (L44649) and race, grease seal, grease cap, and galvanized lug nuts included.

by:

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.



by:

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.



by:

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!



by:

Worked just fine, like everything else I have bought from you folks. Your product knowledge when needed is always helpful too.



by:

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!



by:

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!



by:

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!



by:

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

  • Replacement Hubs for 2000 Coleman Sedona
    Sometimes the numbers wear off of the bearings in trailer hubs but what you can do instead is use the diameter of the spindle where the bearings ride to determine what would be correct replacement. Use this picture as a guide and let me know what you have and I'll help: https://images.etrailer.com/static/images/pics/q/u/qu87803_800.jpg

  • Replacement Idler Hub For Tie Down 11029C On 1-1/16" Straight Spindle with 5 on 4-1/2" Bolt Pattern
    You will need either the Dexter Trailer Idler Hub Assembly for 2,200-lb Axles # 8-259-50UC1 for 8-12" wheels or the Assembly # 8-258-50UC1 for 13-15" wheels. Both these hubs use the 1-1//16" Bearing # L44649 for inner and outer bearings. And they use a Grease Seal # 10-9 (1.50" inner diameter).

  • Replacement Hub for Lippert 2,200 lb Trailer Axle
    Thanks for the info you listed for your Lippert axle. Based on that I can tell you have a 2,200 lb trailer axle that has hubs that have a wheel bolt pattern of 5 on 4-1/2 inches so for a hub you'd want the Dexter part # 8-259-50UC1. Dexter hubs fit on Lippert axles and are widely considered to be the best made hubs. If you wanted just a bearing kit you would want the part # BK1-150. The hub I mentioned does come with bearings.

  • Replacement Hub Recommendation for 2,200 lb Motorcycle Trailer Axle with 5 on 4-1/2" Bolt Pattern

From the information you gave me it sounds like you're needing the Dexter Trailer Idler Hub Assembly for 2,200-lb Axles - 5 on 4-1/2 # 8-259-50UC1, but I do recommend pulling your hub and checking the part numbers on the bearings and seal or measuring the spindle where the bearings and seal ride to make sure it fits. Here are the bearings and seal used for this hub: Inner and outer bearings - L44649 (1.063" inner diameter) Grease seal - 10-9 (1.5" inner diameter...

  • Looking for Galvanized 4 Lug Trailer Hub Compatible w/ # T20BTR-6048 Dexter Trailer Axle
    The # T20BTR-6048 Dexter 2K axle you referred to is compatible with a L44649 inner and outer wheel bearing. The # 8-91-05UC1 hub assembly has a 4-on-4 bolt pattern and uses the L44649 bearings. A galvanized version isn't offered, but there's one available in a 5 lug on 4-1/2 bolt circle, part # 8-259-50UC1 for 8-12 inch wheels or # 8-258-50UC1 for 13-15 inch wheels. Keep in mind, if you switched to the 5 lug hub, you'd need to swap out your existing wheels for wheels with a 5-on-4-1/2 inch...

  • Looking for Replacement Hubs for Boat Trailer with 1.06 Inch Diameter Spindles
    Since you successfully measured your spindles, it sounds like you might have a digital caliper lying around somewhere. Measure the hub bore (inside diameter of hub where grease cap sits). If this diameter is 1.98 inches, your existing bearings are # L44649, in which case the # 8-258-5UC1 hub you referenced would indeed be a correct replacement. Since the hubs are going on a boat trailer, I'd recommend you use galvanized hubs like part # 8-259-50UC1. The hubs are identical to the ones you...

  • 5 Lug Hub That Can Fit Spindle with BTR Dimensions
    Thanks for the picture you included that has the dimensions of your spindle. Based on that you do have a BTR spindle so for a hub with the 5 lug bolt pattern you wan you'd need the # 8-259-50UC1 and you'd be set. Your spindle not having a grease fitting is also not a big deal at all. That does not affect the fit of the hub to the spindle at all.

    In order to spec the correct replacement wheel studs, I'd need the dimensions from one of your existing wheel studs, as shown in the provided diagram. I spoke with the nice folks at Triton Trailers to find the specifics about your existing hubs. For a replacement hub, I'd recommend part # 8-259-50UC1 which is compatible with a 2200 lb axle. The hub has a galvanized finish to resist corrosion, and includes the inner and outer L44649 wheel bearing, and has the L44610 races pre-installed....

  • Replacement Hub for 1989 Ranger Trailer
    Judging by your photo, your trailer would use an idler hub, not a hub drum. Assuming you have 5 lug on 4-1/2 inch bolt circle wheels that use an # L44649 inner and outer wheel bearing, you have a few choices. Rather than the painted hub, I'd recommend going with a galvanized hub for greater corrosion resistance. Dexter hubs are manufactured in the US, which is what I'd recommend. For an 8, 10 or a 12 inch wheel, use # 8-259-50UC1 for a standard spindle or # 8-259-50UC1-EZ for the EZ Lube...

    Since both of your bearings are # L44649 you would want a coated hub like the part # 8-259-50UC1 since this is for a boat trailer. This hub has a Gal-Dex coating to fight corrosion. This hub has a 5 on 4-1/2 inch bolt pattern. If instead you have 4 on 4 inch bolt pattern you would want the part # 8-91-05UC1-EZ. Or for just the bearings you would want the part # L44649 that I mentioned. Or for a bearing kit with new seals and races you would want part # BK1-150. The included seal is a...

  • Replacement Axle for Smaller Boat Trailer with 1,800 lb Capacity
    The CE Smith axle part # CE33201GA is the correct axle for your trailer based on all of the specs you mentioned. For a hub that can fit the smallest diameter wheel size you'd want the part # 8-259-50UC1 which can fit wheels down the 10 inch diameter. Then for a 10 inch wheel and tire you could use the part # AM3H490 and you'd be set. The closest leaf spring to what you mentioned is the part # SP-113275 which is for a 2,000 lb capacity axle and is 23-1/2 inches long. You might need to...

If you can tell me the weight capacity of your axle and/or the bearing sizes for your hub I can recommend the correct service kit. For example, if your trailer has a 2,200 lb axle with the standard 1-1/16" straight spindle, the Dexter Trailer Idler Hub Assembly # 8-259-50UC1 will be the correct replacement hub.

This will allow you to replace the hubs with the Dexter Trailer Idler Hub Assembly # 8-259-50UC1 as long as your axles have not been modified or replaced from the time they left the factory.
