a lift kit extending from a lift kit front end to a lift kit rear end disposed between the wear shoe front end and the wear shoe rear end, the lift kit including a lift kit projection slidingly disposed in the circumferential groove.
11. The track assembly of claim 10 , wherein the lift kit has a first width and the lift kit projection has a second width smaller than the first width.
12. The track assembly of claim 11 , wherein the wear shoe includes:
a first channel disposed on a wear shoe bottom surface, the first channel extending from the wear shoe front end to the wear shoe rear end and configured to slidingly receive a first rail of a link member; and
a second channel spaced apart from the first channel, the second channel being disposed on the wear shoe bottom surface and extending from the wear shoe front end to the wear shoe rear end, the second channel being configured to slidingly receive a second rail of the link member.
13. The track assembly of claim 12 , wherein the lift kit includes at least one slot, the lift kit being attached to the wear shoe at an inner periphery of the at least one slot.
14. The track assembly of claim 13 , wherein the lift kit is attached to the wear shoe by a welded joint.
15. The track assembly of claim 14 , wherein the lift kit includes a hole, and the wear shoe assembly includes a pin engaged with the hole.
16. The track assembly of claim 15 , wherein the pin includes a lock pin hole configured to receive a locking pin.
17. The track assembly of claim 10 , wherein the front wear shoe transition extends from wear shoe front end to a first distal end disposed between the wear shoe front end and the wear shoe rear end.
18. The track assembly of claim 17 , wherein the front wear shoe transition has a first thickness adjacent the wear shoe front end and a second thickness greater than the first thickness adjacent the first distal end.
19. The track assembly of claim 18 , wherein:
