The history of the lift kit is a little murky in my mind, but I think the following is more or less right. Corrections from other members are solicited.
As I recall, the axle was bolted to the frame, and the lift kit was not offered by the factory, before about 2002. Some aftermarket lifts were available.
Between about 2002 and 2005, a lift kit could be added by the factory on special request. The lift kit was an unacknowledged option at build time, and was bolted in by the factory when ordered.
Starting in about 2006, the axle was welded to the frame, and the lift was a standard welded-in feature. The lift was optional but commonly ordered, especially for TMs delivered in the west. Due to its popularity, the lift quickly became standard equipment, and the option became NO LIFT KIT.
Starting in late 2006 or 2007, the lift was removed as an option, but the standard axle had a higher resting angle, which in effect provided the same amount of lift. At this point, the higher-angle welded-in axle became standard, and NO LIFT KIT ceased to be an option.
I'm sure there are errors in the dates here. But the bottom line is that in the early days, such as 1991, the axle was bolted to the frame. Adding a lift is a matter of unbolting the frame from the axle, raising the frame, inserting the lift tubes, and rebolting with longer bolts.
