When I first checked mine at 50k three were at .010/.020 and three were at .008/.018. I don't know how they do it at the factory, but that could have been due to just human error. I set the 1st three down to .008/.018 so they'd all match.

The truck just went over 100k last week, so they are due for a check. We'll see...

Good to know. I would imagine if your gap got too wide you would have started to hear some ticking noise. Well, maybe not with all the other rattling and noise under the hood?

They can wear in or out, depending on how you use the truck.
