Power Producs Professional Ring & Pinion Setup Tool
Designed to accurately measure pinion depth and ring gear backlash. The difference between this tool and other manufacturers is that this one uses the carrier bearing races to more accureately determine the centerline of the carrier. This is far superior to the "split the cap" method. Features a dial indicator instead of a height mic, making it easier to use. Designed for pinion depths from 1.000"-3.000". Works on Chev/GM 10 & 12-Bolt, 8.8 & 9" Ford, 8.25" & 8.75" Mopar, all Dana (except 60), as well as others.
