I used this same kit. The rear axels had to be removed, now the caliper is on the back side. I can skate, the watt keeps the rear end centered :cool:
Why did you remove the rear axles? In order to change the orientation of the brake backing plates because you had clearance issues? Mine are mounted forward on the rear brakes. I have a 3 link in the rear that keeps things centered. My rear end is narrowed enough to tuck 26 x 12 intros with 10” lips, no clearance issues.

I just flipped the struts to the bottom of the LCA’s on the Tahoe and found out I have the aluminum control arms so no extra spacer is needed. I hope it doesn’t drop it too much. I also modified the rear ride height sensor rods for the 4” rear drop but that’s a guessing game. Trial and error will be my friend there. The stock ones were 4”overall. I’ll try them at 3” and adjust accordingly. Waiting on FedEx to deliver the rear springs and shock extenders.

All done with the 2/4 drop. The rear is still settling but I have about a 2/3 drop now. The auto level is still calibrating too I think. I’ll run an ALC trim set with the Tech 2. $230 total for the parts. Way better than stock height. I didn’t get a before shot in the driveway but the yard shot is still valid.

That looks good. Is it 4wd?

Yes it is. :) And I installed new rear Arnott shocks and a Dorman compressor a couple weeks ago and the Autolevel is still functional as well. I just had to shorten the rear ride height sensor rods.

20250326_161030.jpgGot the drivers side moldings fully removed and entire drivers side cut and buffed. Still waiting on this Michigan weather to figure out its life to get the two door flares on.

Still debating on removing the Yukon Badge from the doors.

I've had something very similar in my '07 for the past 4 years and it's been great. It worked fine with the Bose amp without any fiddling and did indeed sound better than the factory Nav unit I had. However it will not work with the rear seat screen without the Maestro harness, so I haven't bothered to do it since we used the '12 for long family road trips.
