Bootgun pneumatic boot applicator. If you’ve ever tried to replace the CV boots on a car, you will appreciate just how difficult it is to actually get the boot onto the drive shaft. Although we can’t do anything about the stripping down of the wheel and wheel hub, we can make life easier when putting on the boot itself. This ingenious tool, operated by air, opens up the flexible boot effortlessly enabling simple fitting onto the shaft, totally eliminating the need for lubrication and the struggling involved with the old fashioned cone method.
