240 ft lbs is probably strong enough for what you'll use it for. i am guessing, just taking wheels on and off and some other random shit right? i would also assume your wheels take less than 200 ft lbs to keep them on right?
I want one cause I have always used just hand tools and it wears me out after I have to do something. I can't get my u-bolts on a '77 axle off without the truck feeling like its gonna come off jackstands. I guess I'm gonna go with the one I found on CL cause its only $40
