How to Determine Correct Hub and Drum for Older Boat Trailer

Updated 06/01/2020 | Published 05/28/2020

Question:

I am looking for a brake drum kit to fit 8 drums to fit an older boat trailer. As an FYI, the tires that I need to replace it are your Kenda Loadstar K364 Trailer Tire - 6.90/6.00-9 - Load Range C # AM10040. Do you have something like that, or know where I should look? Thank you for your help!

It is possible we have the right hub and drum (which I think is what you were referring to by brake drum kit) for your older boat trailer, but more information is needed to determine the right hub for your trailer, which I can help you figure out.

You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use digital caliper and measure your spindle to the thousandths of an inch where the bearings and grease seal ride. You can use the photo I've attached to see exactly where you need to measure.

Additionally, you need to know your hub's wheel bolt pattern; if you do not know what it is I have added a help article which details how you can find it, as well as a printable bolt hole template you can use. If you get back to me with this information I'd be happy to try and help you find the correct hub and drum. I've also added a link to our entire selection for you to go back to.
