Upper control arm bolt size?????

Nowhere is it indicated in the kryptonite instructions and I have searched everywhere. Ive tried a 23mm (largest metric I have) and its too small, a 1" is too big. What size do I need here? Im talking about the upper two cam bolts. 2016 chevy 2500

Did you try a 15/16? That is slightly smaller than 24mm

So I ended up getting a 1" to work without any damage to the nuts or bolts... but I'd say you are correct. Man the Kryptonites are sure hard to squeeze into the mounts! Got one side done.... on to the other on saturday!

Was in the shop so I checked what size, a 15/16, or 24mm both fit. A 1" is really sloppy, surprised you were able to break it loose without it spinning on head. I'd get the proper wrench when you're re-assembling.

I was actually able to get them installed using the same 1" socket with no damage to the bolt head... must be pretty tough hardware.
