I have a 1" drive, 1500ft# impact wrench and it easily removes those, and the radius arm bolt/studs as well. It takes a 7hp/60gallon compresser with 1/2" hose and no couplings to reduce any of the flow to even operate this thing--and it weighs 40#. But it is something the natives would set on an alter and pile yams around. I paid $99 at a traveling tool tent for it. You need a 28mm socket though. The 1 1/8" doesn't fit tightly enough and it will fawk it up. This baby is a portable earthquake--it's gentle though. Lub-lub-lub-lub-lub and it's off.
