So when we refer to the width of an axle in terms of WMS- WMS we mean the distance between the wheel mounting surfaces (on the hubs). We do this to eliminate the variables of wheel width, wheel offset, and tire width which, if not eliminated, would make for an almost infinite number of possible widths. Back to the 1. 4- Bolt There are many different 1. Bolt. axles available, with an almost dizzying array of possible widths, tube OD's. Fortunately, all are pretty similar, a huge number of. CAUTION* - With this axle, as indeed. I shall present, I know there's at least one person out. This is very. likely true, and is due to the way in which OEM vehicle construction occurs.

Swapping Type B hubs onto where Type A hubs used to be will cause a reduction in axle width WMS- WMS. See section below for pics of the different types of hubs to see why this is so. SRW and C& C.
