Any one over used the Dr. Torque Extension Bar Set? You get 5 colored extensions for your impact, green 65 ft/lb, yellow 80 ft/lb, blue 100 ft/lb, gray 120 ft/lb, white 140 ft/lb. Does anyone like, dislike, opinions? Thank you, Philip.

 

For the price, it looks interesting. I wasn't able to find much information on this on the internet. Either this is a fairly new product, or not many people are buying them. If you buy it, let us know what you think. If it works well, there is definitely an advantage here because you can use this shaft on any size socket. That isn't the case with AccuTorq, because their socket is made into the shaft.

 

This may be a stupid question, but how do these differ from the standard extension.

Here is a link to a picture of the Dr. Torque extensions.

The bars are supposed to flex on each hit of the air wrench once a certain torque limit is reached, preventing you from overtightening the bolt.

 

Like Redford said, the Dr. Torque set lets you know when you have reached the torque setting. The thing I like about the AccuTorq tools is that when you reach the setting on them, they free-spin, so you can't over-torque.

 

I just found a video about AccuTorq, and I was wrong about the free-spinning. Here's a link to it if anyone is interested in seeing how it works:

I've seen these impact extensions used in the local Mavis tire shop. I personally have a Snap-On digital torque wrench and trust that because it is more accurate. I guess for places that deal with the impact needs of lug removal all day, those would not be a bad choice. Since the lugs can be used to torque to within a plus or minus of the rated torque, it works for them.

 

Looks like the AccuTorq and the Dr. Torque extensions work about the same way.

OK for lug nuts but I wouldn't torque a head down with them.

 

I was in the tire business for years and used them extensivly. The accu-torq are very accurate and easy to use, saves alot of time when dealing with a lot of mounts and dismounts. Using a air wrench, you tighten' the lug nut until the nut stops and it is torqued. Different lenghts and sizes for different torques. Even have on up 180lbs. for larger trucks.

However you will need to use a good air wrench with at least 250lbs. torque and have a compressor with 120psi or higher and lots of volumn to make them work properly.
What makes them work is the lenght and size of the shaft. It has been calculated to the proper torque of the particular stick.
Wish I had thought of it.
It is the same principal as using a extension on a ratchet, you lose force the longer the extension.

 

These Dr. Torque Bar set are not applicable to our SD's. The torque value is to low.

Our SD's need 150-165 ft/lbs. These only go up to the 140 ft/lb range.

Just my .02

Accu-Torq will custom make any size you need on request, special order.

Or you can use 140, run up and finish with normal torq wrench.

 

Why bother? Just run it up and finish with the torque wrench.

 

A few years ago Ford sent the torque sticks to all their dealers.
We use them in our shop. We've compared the torque reading numerous times to a good torque wrench. They've always been overtorqued but even. Some of us have been using ones rated for lower torque than called for so the wheels aren't overtightened, i.e. using a 75 ft.lb. stick for wheels that are supposed to be torqued to 100.

I have found them on one website for $25 and free shipping.
