  1. Is camber and or caster built into these axles?

    Is there a specific direction to which these axles need to be oriented due to caster angle?

    1 answer

    1. 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.

  4. 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.

    1. This is a straight flat axle. It can be turned over to raise the height.
