The spring perches or seats on a 3,500 lb straight axle will need to be within 9" on center for the end of the hub face. Therefore, the spring perches would have a minimum placement of 54" apart on center. In order to receive a 3,500 lb weight rating with a 44" spring center measurement you would need to look at the Timbren Axle-Less Trailer Suspension System part # A35RS545. The Timbren System will actually replace the leaf springs as well with a set of rubber Aeon springs which will do a greater job of absorbing road shock and supporting the trailer's load.

I have attached a review video for you.
