In order to determine the correct trailer axle for you I would need to know the distance between the spring seats as well as the distance between the hub faces on your trailer. For example, the Dexter Trailer Axle Beam with EZ-Lube Spindles part # T3584F-EZ-8974 has a 74" spring center and 89" hub face with a 3,500 lb capacity. The correct u-bolts for this axle is part # APUBR-1. If you trailer does not match the above dimension then I recommend using the Timbren Axle-Less Trailer Suspension System part # ASR3500S05 which actually replace both the axle and leaf springs. This system will fit any width trailer frame.

In order to recommend the correct leaf springs for the straight axle option, I would need to know the width and distance between the two eye holes on your existing leaf springs if you have double eye springs or the distance between the eye hole and top of the curve if you have slipper springs.

If the eyes on your leaf springs measure to be 9/16" in diameter then you can use part # 166081.
