Corrosion Resistance for Marine Use

This trailer hub assembly has a zinc coating that resists corrosion, making it a great choice for use on your boat or snowmobile trailer. Galvanized steel is durable enough to last in freshwater environments, but it can be used on trailers that come into limited contact with saltwater as well.

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 - 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 - 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 - Side

Measuring the distance 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:  4.7 out of 5 stars   (13 Customer Reviews)

Corrosion-resistant galvanized steel hub is great for marine use. Fits 3,500-lb axles with #84 spindles. Can be used on idler axles or paired with a 10" rotor for disc brake applications. 1/2" Wheel studs and races are included.


With the outer bearing races already installed, it was very easy to complete the assembly of the new hub. It took less than 10 minutes to add the rear inner bearing, tap in the rear dust shield, add the front inner race, install on the spindle, add grease and screw on the retaining nut. with the addition of the cotter pin and a dust cap the whole installation went without a hitch.

The hubs have performed wonderfully. Loaded up the trailer with a Farmall Cub and haul it several hundred miles with no problems
ALLAN D - 11/08/2016


I purchased new bearings, hubs, brake rotor hubs, brake pads, grease caps with rubber inserts, wheels with tires mounted, center caps and lug nuts. All of it was shipped and received in 4 days with free shipping. I have made many large purchases from etrailer and referred them to many people. They have always been great to work with. The quality is very good and don't have one bad thing to say against them. They are my go to store for my utility trailer, enclosed trailer, camper, boat, and truck. Thanks etrailer!!


I am reviewing the components and etrailer as they are not installed yet. Online ordering was easy - I was contacted immediately with shipping time and tracking numbers - it all went really well. The components showed up on time and in good condition. The boxes were a little hammered but UPS does that. Thanks etrailer good service - good prices: what else do you want?


No problem there all working great


Perfect fit. Thank you!





Perfect great price


Great service knowledgeable people

  • Are Studs on Kodiak 5 on 4-1/4 Trailer Hubs Long Enough to Install a Rotor and Aluminum Wheel
    Once a rotor is mounted to Kodiak hub # Q-HUB84545 the thread length of the studs will be reduced by 0.26 inches from 1.20 inches to 0.94 inches. This isn't a huge loss and provided you use the appropriate lug nuts with your aluminum wheels you should be good to go.

  • How to Pick Out Replacement Hub for 1988 StarCraft Trailer
    In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub...

  • How to Pick Out Replacement Trailer Bearings and Seals for Trailer Hub
    I really wish there was a way to determine what bearings a trailer needed without actually pulling the wheel off and checking, but there isn't. The only two solution I have for you would be to remove the hubs and get the numbers that are stamped on the bearing or for you to remove the hubs and use a digital or dial caliper to measure where the bearings and seal ride (see pic). To pick out a replacement grease seal you will need to measure the diameter of the spindle where the grease seal...

  • Replacement Hub for Magic Tilt Trailer with Bearings L68149 L44649
    Based on your wheel bolt pattern and your bearing info the correct idler hub you would need is the part # Q-HUB84545 that you referenced. While your axle capacity does appear to be higher than what your spindles was designed for this would be the highest capacity hub solution that would fit.

  • Dexter Hub Vs. Kodiak Hub Comparison
    I would go with the Dexter part # 84545BX as Dexter has an excellent reputation and because the brackets where the wheel studs mount on this hub are thicker and tend to be less likely to crack when compared to other hubs that use thinner material there like the part # Q-HUB84545. I attached review videos for both hubs for you to check out as well.

  • Grease Cap Recommendation for the Kodiak Hub # Q-HUB84545
    I went and pulled a Kodiak Hub # Q-HUB84545 to measure the hub bore and found that it measures 1.98 inches so for a cap you would want the # RG04-040 or any of the other caps in the attached link.

  • Can the Trailer Idler Hub Assembly # AKIHUB-545-35-EZ-K be Used for a Saltwater Application
    Although hubs that have a black powder coat finish, like the Trailer Idler Hub Assembly # AKIHUB-545-35-EZ-K that you purchased, will not last as long against saltwater as one with a galvanized finish, like the Kodiak Trailer Hub # Q-HUB84545, you can still use it. The galvanized finish does a better job of resisting saltwater so it is preferred for your situation. Hubs with the black powder coat finish can be used for saltwater applications but you will need to make sure to hose them...

  • Replacement Galvanized Trailer Hub for Spindle with 1-3/8" and 1-1/16" Measurements
    The best way to determine what hubs are going to fit your axle is by checking the bearing numbers that come out of the existing hubs; I'll also add that bearing inner diameters are measured down to the 1/100th of an inch and should be measured with a digital calipers like the # PTW80157. The rough measurements you provided do come close to making the Kodiak # Q-HUB84545 you mentioned a match, but I do recommend either measuring the spindle using a digital calipers or checking the existing...

  • Compatibility of 168255TB Grease Seal with Dexter 8-248-50 or Kodiak Q-HUB84545 Trailer Idler Hub
    The # 168255TB seal is slightly smaller in outside diameter, therefore it wouldn't fit tightly enough in the hub bore of the # Q-HUB84545 hub. The hub is designed to use either a 10-19 or a # 58846 grease seal. The hub you referenced has a 1.980 outer hub bore, so the Bearing Buddies you currently have will work fine. The hub uses a # L68149 inner and a # L44649 outer bearing. If the seal bearing surface of your spindles is about 1.719 inches, the hub would work just fine for you.

  • Hub Compatible with EZ Lube Spindle # TRU74FR
    The EZ Lube spindle you referenced, # TRU74FR is compatible with a 3500 lb axle and L44649 outer and L68149 inner bearings. It would be compatible with the # Q-HUB84545 hub you were looking at. We also offer two other hubs that would be compatible, the # 84545UC1-EZ idler hub and the # 84546UC3-EZ hub/drum.

  • 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.

  • Recommended Timbren Axle-Less Suspension And Disc Brake Kit For Retrofitting 1974 European TT
    I have a different option for you, but there is not a 2000lb Timbren Axle-Less suspension that has a brake mounting flange and a spindle that works with hubs that have the 4 on 4" bolt pattern. The # A12RS440 you were looking at does not have a brake mounting flange. Instead you will need to go with the Timbren Heavy-Duty Axle-Less Trailer Suspension - Straight Spindle - Regular Tires - 2,000 lbs # ASR2KHDS01 for your 1974 European Travel Trailer.

  • Recommended Replacement For A Tie-Down Engineering Disc Brake Hub
    I will start by saying that your TDE 11033L hub uses the # L68149 inner bearing and # L44649 outer bearing, which means you have a pretty standard #84 spindle on a 3,500 pound axle. With that said, we do not carry Tie Down Engendering products, so the actual hub will cause some difficulties. Especially being oil bath as hubs for this size axle were only ever really done by TDE. Just as an example, if you look at the Kodiak Trailer Hub # Q-HUB84545 that will fit the Kodiak 10" Rotor # KR10D,...

  • Hub for E-Z Lube Spindle on Boat Trailer
    In order to determine if hub assembly 8-258-50UC1-EZ will work for you, first know that this assembly is for EZ Lube spindles that require a grease seal with a 1-1/2" inner diameter such as # RG06-020. You are also going to want to remove the hub and take a look at the bearing numbers to make sure your inner and outer bearings are # L44649. Normally that would be enough, but since you sanded the spindle, I also recommend you use a digital caliper such as # PTW80157 and measure the spindle...

    Yes, plenty of people choose to use electric brakes on their boat trailer because of the lower maintenance and cost as compared to hydraulic brakes.
