Superior Corrosion Resistance for Marine Use

This trailer hub assembly is constructed of corrosion-resistant, rustproof stainless steel. It's superior construction makes it the best choice for use on your boat or snowmobile trailer. Stainless steel is durable enough to last in freshwater environments, but it can withstand saltwater applications as well. Even after extended use in saltwater, it shows little to no rust or corrosion.

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"

Very nice hub that doesn’t rust. Would recommend using the SS buddy bearing cap. And spend the extra on the all rubber seal.


The product itself is great. However, for over $xxxx bolts should have been provided for the brackets, and the hubs should have been complete and loaded with grease. One of your competitors sells the package 100% complete. When checking out it tells you what else you might need. Maybe I should have read things more closely but I just figured with everything I was buying why would anyone NOT want the bolts for the bracket or a loaded hub even if it cost more. It cost me 3/4 of a day and $xxx. to run around trying to find the little pieces so I could do the job. I still haven't finished yet. I had the one weekend window to do it in.


Definitely the best product on the market and great service from etrailer team


So it's been a year now, and I love it! With saltwater boating, there's already enough things to worry about breaking, so it's nice to have the peace-of-mind of knowing that I don't have to worry about my corroding brake parts. Sure, it's expensive, but after replacing a few rotors, the break-even point is quickly realized. After one year, they still work well and look great.


Think it could have been shipped earlier, was in stock day I ordered, took over a week before it left the building. Other than the wait, product exactly what I asked and paid for.


great price and shipped super fast


Changed out my old standard steel oil bath hubs for stainless steel and grease hubs. The site was very helpful in selecting the correct parts. The swap out and installation went well (except for a frozen lug nut). Since I launch the boat in saltwater most of the time, I am looking forward to hubs that aren't constantly rusting.

Thanks etrailer!

Ive had these hubs for a year now and they are working great. On multiple occasions,Ive launched in salt water without a wash facility and left the trailer for 24+ hours without any noticeable rust or corrosion. If you launch in salt, i would highly recommend these hubs and breaks.
Rick K - 10/23/2018


great hubs I have them on a snowmobile trailer. Stainless steel is a must on a snowmobile trailer. It's disappointing trailer manufacturers don't think, and use cheap quality parts on trailers that run in nothing but salt. I also converted the cheap rusted electric drum brakes over to SS hyd. disc brakes on this trailer, well worth it! etrailer has all the parts and was great to work with!


Fast service and great products. Easy i nstall.


Great parts and service


Awesome product at a fair price, thanks !


My hubs came well packaged.
The machine
work on the hubs was really clean and done well in my opinion.....They look great!

  • How Much Does the Kodiak Trailer Hub for 3500-lbs Axles Weigh

  • How To Find Replacement Hub For 19-Year Old Trailer
    Since trailer manufacturers used many different components, we have no idea what was used on a trailer. The best way to find the right components is to pull the bearings and get the numbers off the bearings that may be stamped or etched. If you cannot find the numbers you will need a digital caliper like part # PTW80157 and measure the spindle where the bearings ride. Then measure the inside of the hub. I have attached a photo that shows where you can typically find the numbers on bearings...

  • Can the Kodiak Stainless Steel Trailer Hub for 3,500-lb Axles Be Used Without Brakes
    The Kodiak Stainless Steel Trailer Hub for 3,500-lb Axles part # KH84545S will work just fine when used without brakes as a standard idler hub. Please note, you will need to add the Bearing Kit for 84 Spindle part # BK2-100 to complete your setup.

  • Replacement EZ-Lube Grease Cap for Kodiak KH84545S
    The correct EZ-Lube grease cap for the Kodiak # KH84545S would be the TruRyde 2 inch # DC200L-DCRP. This is made of 22 gauge, zinc coated steel giving it good corrosion resistance.

  • Parts Needed to Install All Stainless EOH Disc Brake Components on Trailer with 3,500 Axles
    For the idler hub axle the easiest way to add stainless disc brakes would be a slip on kit like part # K2R35S which has rotors that would slip right over the current hubs and comes with everything else needed to install. To convert the hubs too of this axle to stainless you'd also need the part # KH84545S. Using the hub # KH84545S with the slip on disc kit part # K2R35S with it would be your best option for your current brake axle too since it's the only way to get everything stainless....

  • Will Dexter Actuator 099-175-20 work With Hubs KH84545S and Disc Brake Kit K2R35S
    Yes, everything you mentioned would work great together. The actuator part # 099-175-20 is for disc brakes and has more than enough capacity so it would work great with the disc brake kit part # K2R35S which would fit the idler hubs # KH84545S you also mentioned.

  • Will Kodiak Trailer Hub for 3,500-lb Axles Fit Dexter 80043A Spindle On Boat Trailer
    From what I have found, the Dexter 80043A spindle on your trailer matches your standard 3,500 lb axle bearings and grease seal. It uses a # L68149 inner and # L44649 outer bearing with a # 58846 grease seal. This is also true for the Kodiak Trailer Hub for 3,500-lb Axles # KH84545S which means they will fit and work for your stainless steel upgrade on your boat trailer. These are compatible with rotors like the # KR10S.

  • Bearing and Seal Recommendation for Installing Kodiak Hub KH84545S on MFI/Yamaha Trailer
    The races of the part # KH84545S are installed but the bearings and seal are sold separately. It calls for a # L68149 and # L44649 and then for a seal part # RG06-050 which all match what you say you need.

  • Bearing Kit For Kodiak Trailer Hub KH84545S
    We do have the right bearing kit for your Kodiak Trailer Hub for 3,500 lb Axles # KH84545S, and though they are steel, they aren't stainless steel. The correct bearing kit for your hub is the following: - Hub Bearing Kit # BK2-100 Along with the # BK2-100, if you need a bearing packer and grease, go with the Bearing Packer # PTW1218 and LubriMatic LMX Grease # L11390.
