Could someone explain these to me.

I don't understand how these would work. What would keep them from just twisting? With a torque wrench you could over torque do these click or something? I can't find anything with a better explaintion.
Thanks for any help you can give me.

The way they are supposed to be used is with impact guns, its hard toexplain but they basically start twisting when you reach the appropraite torque setting. The are meant for speed and aren't super accurate, just close enough for quick jiffy lube tire changes. If it we me i'd get a real Snap on torque wrench.

They turn the excess torque into vibration. they are very accurate, and I 've used them for 15 years. I hve used them on very sensative set-ups like ford taurus, rover sterling, and everything else that came into the shop. I've not had a problem with them, and I own a set made by "Lock Technology". If you buy a set, make sure you get a reputable brand. I've never heard of the "Genius" brand before. Look at this copy and paste from a discount website:

1/2" Drive Wheel Torque Extension Kit - 5 Pc. LT 1460
Designed to be used with a 1/2" impact gun Will torque wheel nuts on most foreign and domestic cars and light trucks to the correct torque, the first time and every time Extensions not sockets - You can use these with any 1/2" drive impact sockets Kit includes: 100 ft.-lbs., 80 ft.-lbs, 65 ft.lbs, 120 ft.-lbs and 140 ft.-lbs wheel torque extension. Comes in a molded case with a handy wall chart.

List Price Your Price Qty


$132.76
$86.17

The biggest concern that brought these types of products to the market was the warping of the brake rotors during tire installation. If your primary concern is lug torque on custom wheels, then a good torque wrench is better than these, becasue custom wheels must be retorqued 1 week after installation, and every month thereafter.

Tech, While these may be accurate enough for some things as you say it is not as simple as just sticking them on any impact and good to go. One impact will vary from another and things like air pressure will affect performance so one cannot simply grab up an impact and expect any kind of real accuracy, although they would be MUCH better than a standard extension. In a production environment where the impact setting remains fairly constant and can be checked periodical they can be a handy tool but should not be relied on without checking the impact first. Also you are right about the fact that they work by absorbing torque energy and not by "twisting". Improperly used with a high torque impact wrench can lead to over torquing with these things.

oldred, I couldn't agree with you more. These torque sticks work well if your impact is set to the proper settings. I have used them for over 5 years with out any problems. BUT on the problem cars such as the Ford Taurus and the line of Chrysler's I still will use a true torque wrench. They work well for the run of the mill cars, and well worth the money investment if you repair cars for a living.

I like them but a Troque wrench is quicker

It was funny, I got the snap on guy in my shop and trying to sell me a set of them and I told them that they are no good except for prybars, and he tried arguing with me. So the awsome guy that I am I looked at him and said I would like to try the set out and I want you to watch me with a demestartion. I took my impact and put the speed to full, and took the 100 ft-lbs one and torques on a wheel, I mean I wailed on it. I took my regular torque wrench and put it to 100ft-lbs, and I just had it recalibrated so I knew that the torque wrench was fine that way. Click it goes so I moved it up 5 lbs well I ended up at almost 160ft-lbs. He shut up in a hurry LoL. But I did play with the speed and everything that way I found a spot on my gun about half way where It is within 10ft-lbs so depends. Do the test if you are wondering. I have one and sometimes use it. But I prefer the wrench method. Cause then I know.

Think about it this way, I always look at products in a simular way. You torque on a head with a torque wrench right, would you trust using a torque stick. If you don't trust using a torque stick on a head what difference is it between using it on wheels. And ya someone mentioned about retorquing mag wheels after a week, yup that is right I had a couple of my customers come back to me I offer the service for free and I know that I was surprised on how many of them will actually move!

This test was not the proper way the tool was designed to be used, if you read the directions you need to turn down the impact to the proper setting for the torque stick that you are using. I agree that the torque wrench is the best, but you cant blame the tool for not performing well if it is the operators fault. I have also seen many junk torque wrenches that were of the torque mark even when properly used.

I agree that is not the proper way to test these things but it does point out the fact they are not what a lot of people think they are. Dart had apparently run into a dealer(the Snap-On guy) who has(had) the very mistaken idea, like too many others, that these things will simply limit the amount of torque no matter what the input and I know a couple of guys who will insist this is true in spite of the facts. I have even heard of guys using them with a breaker bar for a torque wrench When properly used they can be a handy tool to help prevent over-torquing but one must understand the limitations.

Good point about the Gun setting. I forgot to say that I had my IR231 set for them, after testing it on my own steel-wheeled Ranger one night. Watch the air pressure as that will also make a difference.
