This Reliable underslung axle has a camber built in to the axle. There is not a front or back way to install. The spring mounts must be at the bottom for correct installation.

Axle tube, square or round?

This part number at my local Northern Tool has a round axle. The description on your site says it's a square axle. I'm looking for a square one. Do you carry them square?
Thanks,

Question

Is this axle flat or does it have built in camber?

Can it be flipped so that I can add clearance height under the trailer versus bringing it lower to the ground. Not going to modify and not concerned about voiding warranty.
