These according to YouTube vids are the strongest air impact 1 wrenches you can buy. I don't doubt it either. I haven't used the long anvil much yet but there were some Allen Head bolts that hold the cap on the end of the main boom cylinder on my John Deere 437e Knuckleboom Loader that I needed to get out. I threw everything at them I had on 2 service trucks, including Harbor Freight and Chicago Pneumatic 1 guns, and they wouldn't budge. Even broke several impact pieces and still no budge... They used 17mm allen heads and im not that familiar with metric sizes that big but thats a big bolt, probably over an inch and a quarter if they were sae. My short anvil Ingersoll 2850 was at home and I brought it the next day.... I already had owned it a year before buying the long anvil.... It ripped them all right out at about 130 psi and hooked to only 3/8 fittings (although I do have 30 gallon 2 stage portables on service trucks, I need to upgrade my plumbing)! With 3/8 connections they will out perform any impact I have ever touched! When you plumb them to my big Speedaire 7hp 80 gallon 2 stage at my shop where there is nothing smaller than 1/2 carrying the air then they truly go into Mega Beast mode! I mean get in, sit down, shut up, and hang on!! They also easily peel the lock nut off the shaft inside those cylinders and they require a 3.5 socket. Lugs on road tractor and trailer wheels are childs play for these impacts, short or long. Look at the pic, I know, I have them both! They are crazy light as well. And, they have their triggers on the handle interior, which is so much better than having that snake trigger ready to strike on the exterior! Take it from me.....30 years in logging business and working on my heavy equipment.... you can't go wrong with these impacts!!
