ProForm Pinion Depth Setting Tool with Case

If you are not familiar with Ring and Pinion set up, learn the basics first. There are some bad reviews related to not understanding how to use it. This tool is not intended to teach you how. This tool is very effective for determining pinion position.. It provides an accurate method for obtaining the pinion position on many axle models. I definitely will be recommending it to a lot of people. As a former trainer for the Dana Corporation Axle Classes, This tool provides an inexpensive alternative to the very costly tools of the past. It simply gets the job done. I did have a problem, as some have indicated in the negative reviews, with the dial indicator. It was very rough. I contacted Proform and had a new indicator in no time. I would not reduce the number of "Stars" just because of that. This tool is too good to mislead someone over a defective dial indicator that Proform made right immediately. Great company, great tool, great price. Bob

Set up is a little touchy but once it’s set up it works awesome. Takes all the guess and trial and error work out of setting up your pinion. Perfect tooth pattern after the first adjustment. Similar tool from Snapon is $600. Worth the set up time.

Not real hard to figure out how use could be made with a few more holes

The calibration tube was too long for the extension rods. This tool has no chance of working if I can't calibrate it and it's put me behind now waiting for a better brand. This is the absolute worst tool I've bought in many years.

I did not actually use this tool but I did inspect it. I did see how it was supposed to work. There were some good instructions provided and if you take the time to follow the instructions, and check your work, this tool will absolutely work for fraction of the price of other pinion depth tools with a little bit more math and a little bit more work.

Indicator works as expected, though I am unable to get the 3 inch extension pin to thread into the indicator. It slips right in and out. Threads don't even touch the indicator. Its impossible to get an accurate reading due to a defective part. The shorter pins did thread in better than the long one, but no chance to set up a differential correctly with out the longer pin.

Good for the cost. Just be very precise when using

Very good for the price

Very nice

For the price, you'd expect Proform to have rectified the QC situation by now, or at least reinspected these before shipping. Nope, the indicator I received was so stiff it was unuseable. Quite telling about the Proform brand and their disinterest in quality control. Has definitely soured the brand in my eyes.

Finally got accurate measurements. The extensions screw on crooked. Very difficult to use and time consuming. Good for the price point a better tool is 4 to 5 times the money.

1 of the needle extensions had threads that were too small to secure Onto the dial indicator(which happened to be the one I needed!, collet that secures the dial indicator was too tight(even with the lock but off) so I couldn’t move it down far enough to properly calibrate the long extention. Useless trash, Sending it back...
