I need to purchase a replacement axle on a homemade boat trailer. I’m assuming 3500 lb capacity, no brakes, or grease zerk. Hub face width: 73” Spring width 59-1/4” Feel free to contact me at anytime

Hi Terry; we don't have any 3,500 lb axles that match your 73" hub face measurement. They are either 89" or 95" which won't work for your trailer. What I can offer is the Timbren Axle-Less Trailer Suspension # ASR3500S05. This fits any frame width and replaces/upgrades your suspension.
I did run a search and it looks like there are 3,500 lb 73" axles out there, just none that we carry. The spring seat measurements I saw don't match so if you decide to get one of these you will need to cut off the spring seats and weld on # TRSS238 to match your 59-1/4" measurement.
