Do You Have a Replacement Hub for a 1.25" Straight Spindle?

Question:

Hi, I am wanting new hubs with the bearings for my boat trailer. The axle is 1.25 where the bearings ride. I am having an issue finding a set on your website.

Hey Tony, welcome back. We still don't have a hub that's going to fit your 1.25" diameter spindle. I do not expect to get one in either. They just don't make parts like that for older trailers anymore.

My solution from over the summer of swapping out your spindles or axle is still the only one I have. If you would like to see the options available to replace your axle, I would need to know the hub face and spring center measurements.

I've attached a couple of diagrams below so you can see what dimensions I need.

You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

@TonyS Thanks for the measurements. We do not have a standard axle with those dimensions. The only option I have is to use the Timbren Axle-Less Trailer Suspension w/ Idler Hubs item # A20RS545. These will bolt directly to your boat trailer's frame and include idler hubs with a 5 on 4-1/2 bolt pattern.
