Park Tool Wag-4 Professional Wheel Alignment Gauge

Easy to use

Works great, accurate! Only issue is the item is used not new in the package. Item has some cosmetic damage like its been banged around but nothing that affects its accuracy or use.

The best tool for the job,excellent quality. Fast shipping, great packaging, no need for spare, give this to your grandkids!

If you know what this is the odds are you are getting it. Beside a hand built dishing tool this works like a champ. Make sure and store it correctly when not in use. I have some scrapes in the plastic from storage and being dropped that I have had to file down to make it true.

Useless.

Works great and very necessary for a full wheel check.

Its a little weird to use, but once you get used to it, its great. The older alignment tool was a little easier to setup. It had a more precise indicator. But, so far, the way Ive found to use this is to check that the blocks are hitting the rim, and not the tire. Push the center gauge part down into the concave part, and tap it over the axle of the wheel. Get it so that it clears the axle if you slide it back and forth over it. (Check for clearance) And then flip the wheel over and look at the back side. You should get a better reading doing it that way. Its a pretty awesome tool, and can save a lot of time and futzing with caliper adjustments. A must have for wheel builders.

Good quality dishing tool. I use this for personal use but it is well built for commercial shop use as well. I like the adjustable feet that allow adaptation to lots of sizes. I trust park tools for a quality product. Dishing can be easily checked with this tool for wheel adjustments.

It does the job, but adjusting the gauge is annoying because it moves as you tighten the knob. It can only really be used with the wheel in the stand, because you need to grasp the gauge with as many fingers as possible (to hold it still) while you rotate the knob with whatever leftover fingers you have left. The WAG 3 is a much better design.

If you true/build wheels, this is a must have as I have built tens of sets over the years, but only 30% correctly. You need the right tools for the job as I am proof that anyone can build a wheel, but not everyone can build a wheel right.
