My first "REAL" Impact.
Size: 1/2" Impact - Front Exhaust
**Update to prior review** --- I have put this impact to the "test" for just about the last year now. I have worked on many of my friends and family members vehicles doing various brake jobs and a variety of other jobs. This thing still amazes me each time I use it. Works just like it should/like new and hasn't skipped a beat. I'd say I'd probably never have to buy an impact again, but considering I keep picking up brake jobs and having to deal with my own personal 20+ year old vehicles various ailments I am not quite sure, haha... Original Review: Prior to this purchase I have had a Husky impact that was in a starter kit along with my air compressor and I have also had a Craftsman impact that I purchased to replace the Husky when I returned the kit due to the compressor being a piece of junk. The craftsman gun was terrible, it was considerably worse than the husky impact that was included in the starter kit even though everything that was listed in the product specifications either matched or so called "beat" the husky. I wound up selling the impact for 20.00 because it wouldn't even remove lug nuts from tires. I have used this one to rotate tires on my 20 year old truck, I used it to remove some seat bolts from failed seats, and I have also used it for various other projects on my wifes and my own vehicles. This is the best impact that I have purchased. You really get what you pay for in tools. If you are looking for a decent quality impact for under $100.00 you might as well stick to hand tools because you won't get it. One question though, on such an overall quality/solid impact why does it have to have a cheap plastic trigger? I feel like when I just look at the trigger its going to break off. Other than that this tool has done the job and more. It has already tore the heads off of a couple of seized heavy duty bolts so it certainly does not lack power. ... show more

Great tool
Size: 1/2" Impact - Front Exhaust
****Update 1/2/2013**** I have used this impact gun a great deal since my last review, and this gun is still holding strong. I recommend you purchase the IR air tool oil. I did buy the protective boot for my gun, its red and takes regular abuse (gun occassionally gets tossed to the side un-intentionally while I'm working) and my impact gun is still looking great! I use this gun for A LOT of different things, most recently: Busting off the bed nuts on my GMC project truck (nuts were rusted), leaf spring removal, front suspension A-Arms, Honda suspension rebuild: McPherson strut removal, sway bar, hub-bearing removal and install (this was so sweet, i bought the bearing kit on Amazon as well), I can go on and on. You wont be disappointed with this gun, for the price and performance, you cannot beat it. Note: I grew up fixing cars with my dad, so a word of advice from someone who has been doing this a while: Don't skimp and use your regular sockets with ANY impact gun. Spend the money on real impact sockets and use impact grade U-joints and extensions. Regular sockets WILL crack because of their thin-wall design and are simply not up to the task of taking abuse from an impact gun. You cannot put a price on your safety, and ER visits because a shard of shattered socket flew in there should not be in your plans. I still stick with my opinion that if you choose an impact gun, make sure it is serviceable (can be opened up and you can purchase a rebuild kit for it) this alone will ensure your gun will be around for years and years to come. A lot of the other guns i shopped for were of a sealed/riveted design, and wont allow servicing should you need it. ****I highly recommend this gun to others.**** Gentlemen, I recently purchased this impact gun, which would be my first. I must say that i love the power. I use it for tire rotation, brake jobs, crank pulley bolt removal, etc. The torque is great; I can't even turn lug nuts any further than this tool can by hand. The power selector knob is great for varying power to the socket. I bought the IR 14pc socket set (metric), which by the way, are beautiful! too bad the finish gets messed up as you use them. I chose this gun over a Craftsman impact, the particular one could not be rebuilt with a kit like this one can. Beutiful aluminum finish on the body, I think I will buy a protective boot for it. ... show more

231C vs 2130 Comparison
Size: 1/2" Impact - Front Exhaust
I've had a cheap Husky impact for quite some time. It wasn't overly powerful so I was looking for something a bit better. I received an IR 2130 as a gift and was really looking forward to using it. I have borrowed a neighbor's old IR 231 several times for jobs my Husky just couldn't handle. So, I knew I wanted an IR impact. After trying out the 2130 on some lug nuts, it removed them with my large compressor but didn't knock them out near as quickly or easily as I was expecting. When trying to use the 2130 on my smaller compressor it wouldn't even touch the lug nuts. So, having used a 231c in the past, I thought I would pick up a 231c to compare to the 2130. The 231c was able to fairly easily take off lug nuts on my F150 (150ft-lbs) even on a small portable compressor with a 1/4" line going to it. When hooked up to my big compressor with a 3/8" line it rips them right off effortlessly. This impact is heavy, loud and hits HARD! Compared to the 2130 it's much louder, slightly less ergonomic and seems to hit harder. But, I'm a weekend wrencher and enthusiast. I think the 2130 needs more air to really shine. If I was using it daily in an automotive environment I might lean towards the 2130 for most jobs and an Aircat for those really stubborn bolts. But, for what I use it for, the 231C will do the job well and if it's half as well-built as the old USA made ones will likely last me a lifetime. Pros: Works quite well even on a limited air supply With a good air supply really hits hard (Much better than my cheap husky and in my opinion better than the 2130) Well built, feels like a tank, parts readily available There's a reason they've made this same impact for 20+ years! Cons: It's loud compared to other newer designs Trigger seems to work well but the plastic feels cheap to me Made in China (although it doesn't appear the the quality is any different than the older USA built impacts) I did a lot of reasearch and looked at a lot of reviews. Ultimately I'm happy I went with the 231c. The 2130 is a good wrench but not what I was looking for. Hopefully this review helps someone decide which impact to buy! ... show more

Works well and be aware of your compressor size and scfm requirements
Size: 1/2" Impact - Front Exhaust
This impact wrench is really good. It took off my lug nuts with power to spare and fastened them with ease and tight enough to satisfy me. Have a craftsmen impact wrench and it lacked enough power to torque my lug nuts and other car projects so now have this one to replace it. Have a compressor that is a twin cylinder 30 gal tank rated at 5.3 scfm. and it kept up with my demands on it, ran once per tire and is no big deal with the amount of times it turned on, I figure a possible 4 to 5.3 cfm on this wrench. Unable to find a rating for this wrench as in how many cfm is needed to run this thing, so this is a complete guess. Oil came out the exhaust to a point I had to wear gloves until this issue eased up/ stopped, which it did. Over all the wrench is easy to use and has enough torque/power to get the tough jobs done. I would recommend this wrench but would be aware of the size and the scfm. of your compressor to be sure it will run this wrench. ... show more

Quality air wrench, for sure!
Size: 1/2" Impact - Front Exhaust
I've had this for a couple of weeks now and I couldn't be any more pleased. I dropped a few drops of air tool oil in it and proceeded to rotate the tires on my RAM 2500. Made quick work of the lug nuts with plenty of torque to spare. I had actually already bought a torque wrench from Harbor Freight, but at the check out, they asked me if I wanted the 3 year extended warranty for $45? I asked them how long the manufacturers was and they said 90 days. I was a bit surprised that they didn't expect it to last more than 3 months so when I got home I looked on Amazon and found this for the same price AND it came with a 1 year manufacturers warranty. Needless to say, I returned the Harbor Freight tool and glad I did. ... show more

Great impact
Size: 1/2" Impact - Bottom Exhaust
This impact has enough torque to get my lugs off my truck and remove rested nuts with ease. I recently completed a harmonic balancer replacement and it was only possible with this impact. Ingersoll-Rand and specifically the 231 has countless testimonials from people that have been using the impact for 20+ years. These impacts will last forever if taken care of properly and even if you neglect it people report of it working for decades still. All you have to do is oil daily before and after use and install a water/oil filter on your air hose line. Water from the compressor can accumulate and rust the impact if no filter is installed but again this will last for years and years without one. A lot of the new impacts are plastic and supply more torque. When advertised the composite plastic air impacts seem awesome. They usually promote the light weight high torque capacity. Well this 231 Ingresoll impact can handle any job I have thrown at it with ease. There are five setting and I have no issue with it ripping bolts off. A problem with the composite plastic is they do not last as long. Metal can outlast plastic any day obviously. As for the weight of a metal impact, it is not bad at all. The only time you will notice a difference is with prolong use. I would recommend this to anyone and the HA is a nice feature. HA stands for hand air which means the air output comes out from the bottom and not from the front. This directs the air away from your work area and prevents car dust and deposit from flying all over. ... show more
