Despite the name and looks, don’t expect the alien horde to wave these around when they come for Earth. This $310 oddball is designed to spread CV joint boots wide enough to slip the narrow end over the bearings to save time. I can’t say I’ve ever met anyone without the patience to remove the joint’s circlips to install the boot, so this is probably a production-only or very specialized tool. It seems to use an adjustable air supply to apply enough torque to spread the boot, but I can’t be sure since I’ve never used one.
The only reason I mention the Rapid Flexx is the sheer oddity of this thing. Why spend over three hundred dollars to save five minutes? Maybe some CV joints are just more of a headache than I’m used to, but I honestly have trouble seeing the point of this one. And I own a special socket for Ecotec oil filter cartridges. What say you, Toolmongers? Can you think of a time when the cost would be justified?
