2017 Silverado Z71

Started off by using a small Dremel burr bit to grind down the fins. The spacer slipped through between the crossmember bracket and the fin easily before cutting. So I thought I would not have to trim much at all. I will find out when it lowers but I ran into a snag.
I made sure I selected the kit from Supreme Suspension with the longer bolts for the Z71. Nope, they are too short. So tomorrow I will have to hit the hardware store but I would like to know if anyone has done this kit on a 2017. If so, how much of the fun did you take off.

The longest bolt they sent is way too short.

I read through that before I started and then went back and stared at those pics. It seems that diff fin design between the two are a little different.

I could take the spacer and slip it through with ease before I cut. So by trimming a 1/4” , you still think it’s not enough. Was trying to do this without unbolting anything but the four mounts.

they used the same diff from 14-18.

I did the same thing to a 2016 as well.

you have to unbolt the crossmember to make your life easier.

But You dont have to remove the entire diff.

Got home and found the spacer is 1/2” thick. So there’s the difference. You said your space was an inch right? So what good is this spacer really going to do at just 1/2”?

Yep I see it. Missed it when scrolling around.
Here’s a shot of where I’m at with @ 2.5” of lift. Going to drive for awhile and see if it settles but I may back them off a little.
