It is possible to mount the springs on top of the axle which is called "flipping the axle". To accomplish this we normally recommend an over-under conversion however there is not one with square u-bolts available for your square axle.

Instead I recommend to use CE Smith U-Bolt Kit for Mounting 2" Square Trailer Axles - 4-1/2" Long U-Bolts - Zinc part # CE23103 which is galvanized for boat trailers. The U-bolts measure Inner width of 2-1/8" with a length of 4-1/2" and diameter of 1/2". The kit comes with 2 U-bolt plates for 1-3/4" springs. I recommend to re-weld the spring seats to the other side of your axle because we do not have spring seats that will work.
