Yukon free spin kit with factory alloys?

You certainly improved the studs, I’m just not sure it was necessary and that might explain Yukon’s stance.

Half a lug but engagement is ok with you? It wouldn’t be for me either, that’s for sure.

The OEM lugs don’t have threads all the way thru them so it’s not 1/2 engagement, it’s full engagement from what I recall on my Yukon kit and OEM aluminum wheels.

The supplied Yukon studs are 2.325 under head length. The Spindle flange thickness is .467, the rotor thickness is .393 and my wheel
flange is .770 which totals 1.63 which left only .695 protruding from the wheel flange.
I applied some Dykem to on a lug nut and found the thread engagement to be about .670 which might be fine but I’m OCD on this stuff
and for the price of these free spin kits I thought it should be at least the total length of the lug nut.

It doesn’t need to be the total length of the lug nut, just the total length of the threads. Think about the closed end lug nuts that might not get full engagement ever.

It’s pretty sweet how you modded then thou.

Maybe I missed this before, but from this explanation it sounds like you were perfectly fine as only .015” wasn’t engaged. That’s not much considering how much you did have. I still agree with you that Yukon should’ve stepped up and explained this better. I wouldn’t have had a “warm fuzzy” seeing and thinking what you were either.

John, again, now that I understand it better, I tend to agree with you as well.

I’m a bit old school and even anal about stuff like this. As we should be really. Perhaps it’s from my aircraft mechanic days. If it didn’t have a thread showing past the nut, it was a no-go.

Just for giggles, I’ll tell you this. I’ve heard old timers say full strength of a nut and bolt is generally achieved with 3 full threads. I doubt this holds true today as there are many many specialized bolts and fancy alloys now. But maybe back in the day that theory held more water.

John, you’re correct the thread engagement is really what matters but in my case the thread engagement was 5 threads less than the lug nut and with an 18 pitch is .275. This bothered me but as I stated earlier I’m OCD and it’s corrected at least to my satisfaction..
I’d like to thank everyone for the replies and input, I can’t imagine owning one of these trucks without this site!
