Lots of ratios and applications are available.
Maybe I got a bad gear set, but these 4.57 Motive gears would not allow a good pattern in a stock Ford 9-inch. The ring and pinion ate itself before the weekend was up.
Bottom Line:
Motive part number F890457: I had to keep pulling shims from the pinion support until there were no shims left. The gear required an even deeper setting but it was not possible without machining the housing. I must have gotten a bad set of gears. Should have returned them but I was on a short timeline.
