Claims20
An axle system comprising:
- an axle;
- a hanger bracket;
- a trailing arm that is fixedly coupled to the axle and rotatably coupled to the hanger bracket such that the trailing arm is rotatable about a pivot axis with respect to the hanger bracket, wherein the trailing arm has a bottom side that faces away from the hanger bracket, a first lateral side, and a second lateral side that is disposed opposite the first lateral side;
- and
- an axle lift kit that includes:
- a first bracket subassembly that is fastened to the hanger bracket;
- a second bracket subassembly that is fastened to the first lateral side and the second lateral side of the trailing arm, wherein the second bracket subassembly is spaced apart from and not attached to the bottom side;
- and
- a lift air spring that extends between the first bracket subassembly and the second bracket subassembly and is configured to rotate the trailing arm about the pivot axis.
