Options change the numbers
The ProStar was introduced in 2007 with 113-in and 122-in BBC options. The MaxxForce engines were Navistar's in-house offering; the Cummins ISX and Cat C13 were alternatives. The MaxxForce 13 later became the A26 in 2017 when International redesigned it. The ProStar was replaced by the LT Series in 2017.
