Replacement Axle Recommendation for 49.5 Spring Center and 59.5 Hub Face Measurements

Question:

I have utility trailer I bought about 30 years ago at Builders Square. The trailer has a 49.5 inch spring center distance. The hub face distance is 59.5. I put some 4 on 12 inch wheels on it that use radial tires. I also have a set of spacers I can put on the mounting hub faces that increase the hub face distance to 61.75. I do not know the load capacity but the most I haul with it is about 1200 lb. The trailer has a 4ft by 8 foot long bed. It looks like the spring spacing on this this is an oddball. I would like to get a 1800 to 2000 lb solution if possible, not that I would haul that much, but would like the margin.

For a standard axle we have the Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern # e25GR which is rated for 2,000 lbs but the spring seats are 48" apart on center so for this to fit you'll have to cut off the current sets and have new ones, part # TRSS175, welded on.

Because of this I recommend picking up the Timbren Axle-Less Trailer Suspension System # A20RS440 instead. This is also rated for 2,000 lbs but it uses brackets that install directly to your trailer frame and the suspension is Aeon rubber springs which don't have to be maintained nearly as much as a standard leaf spring setup.

Attached are review videos of both axles systems for you to check out.
