hey sterling
the races are universal for the 1 and 1 1/16 axle...the bearing size is what you have to watch. If you have a 1 1/16th axle you need to L4469 bearing, if you have a 1 inch axle you need a L44643 bearing.
The seals are also size specific. I cant remember the product code as the packaging had it printed on the front of the package.
Honest opinion here, if you dont require a short hub, go and buy the standard canadian tire trailer hub, its a cheaper and easier way of doing the whole process, for literally the same price and this way you dont have to pound the races in and out.
I broke my hub trying to put the races in and I was even using the proper tool for it. The races come pre installed in the new hubs, my kit even came with bearings but unfortunately I had the 1 1/16th axle so the bearings didnt fit.
I ended up spending just as much on bearings as I did for the whole Hub, races, bearings, and pins.
We finally got our new short hub this weekend and the job was a 10 minute fix.
