Always a pleasure to use Ingersoll Rand air tools. This little beast really does pull 600 + pounds of torque. I use it everyday, drop it occasionally from a height, and it still whirs like the day I opened the box. I am buying different ones from I.R. because they are built tough and true. BTW I rebuild locomotives, so I abuse the snot out of these tools.

Has worked great for changing from sumer to winter tires. Not the most torque but it's durable enough to toss around and not have to worry about. I use it in freezing temps as well as hot. The adjustment dial is kinda of wonky and is the only thing that i think could be improved but that would probaly make it more expensive and i don't use it enough to justify.

I just used the 231C for the first time since arrival and it's already everything I had hoped for and more. My brother bought me my first impact for Christmas probably 10 years ago and after trying to use to rotate my truck tires was a disaster. It wouldn't even remove one lug hand torqued to 100 ft lbs. So after doing some research the Ingersoll-Rand name kept coming up and with the very favorable reviews and I made my choice.

I went back out today to try and rotate again and every single lug nut came off with ease. I have a 15 gallon Craftsman compressor, nothing special, but it only ran 3 times between removing and re-torquing 6 lugs per wheel. Regulator was set to ~100 PSI with 100' of 3/8 hose.

I started the lugs by hand after moving the tires and set the tool to 2. I set the truck down and pulled out my torque wrench and set it to 100 ft lbs. Every lug nut was at least 100 ft lbs. Awesome.

In addition, the impact itself has a really great finish and the adjustments are notchy and precise. I do have an in-line oiler/dryer so I did notice a small amount of oil coming out of the exhaust, but that's to be expected.

I have 100k maintenance coming soon and I'm no longer terrified about removing suspension components for strut changes. I will update with my experience with that soon.

only used a few times so far but I'm really impressed with how it works so far and feel or a heavy quality tool. I took off car tires on the number one setting, very low setting for this gun pounded a little then right off. getting to know how to set air presser takes a little getting used to as it changes from left to right. Directions are in the little book they sent along although very small print and not much other info. Can't weight to try it out on something large and tough as I believe this will work very well. It's made in china but seems to has good quality. Add on. I replaced the front A Arms on my 2006 chev last week and the impact wrench Shure made live a lot easer then without it. Impact worked supper well and still looking for something bigger to try it out on. Wish I had it a long time a go ( girls get your man one for birthday or x mas he will like it a lot )

Good quality and ingersoll rand always had a name for itself, and used their impact guns a lot at work, now I got me the 231c for daily work, it's awesome, great buy can't beat the price
