Did you find your baseball?

Like others here have said, the control arms will break before grade 10 (or even grade 9) bolts and nuts. I’m not scared. I won’t be jumping railroad tracks anyway. @Doug118 had 40k miles on his at the time of his post regarding this setup.View attachment 452997

Mine is flipped as well. Without the spacers it gave me close to a 4" drop.

Carplay sync works pretty good so far. Steering controls working. Pretty powerful volume and bass from this thing. Really woke up the old factory speakers and sub.

Oh yeah, I'm not saying I wouldn't go that route if I were lowering, just wouldn't be the best for my current situation.
...the king coilovers are too tall somehow, I almost mounted them under like to to fix it.
I'll probably have them get me shorter and stiffer springs eventually.

Could you link me those 1/2 spacers? I dont wanna go crazy lift but I wanna get rid of the front squat on my Yukon. I think the Rough Country ones are to thick and would force me to get the back raised. I really just want to raise the front a little bit.

With our suspension geometry, any thickness you add to the strut assembly, will double at the wheel.
Half inch spacer gives you 1 in lift
Back when I had mine leveled, I ran a 1 inch spacer to bring the front end up two inches and it sat perfect

If i wanted a 4" drop in front. would this work with drop struts, and NOT need 2" drop spindles? Or would i need the spindles to keep alignment within spec?

From what I’ve read flipping them to under the control arms gives you about 1 1/2” drop with no spacers added. I’m going to experiment. The 1/2” spacers I ordered should make it 2 “drop. They’re .39 thick.Supposedly every inch of spacer, either on top when used to lift or under if the struts are flipped, result in twice the thickness of the spacer. I’ve never heard of anybody trying to get a 4” drop without using drop spindles or drop struts.

That’s with drop spindles though, correct? Or do you have different control arms? I heard the aluminum ones are thicker.

You are right I forgot I installed 2" drop spindles LOL.

Interesting. I'll have to do some measuring when I get home. I just want to level without squatting when I hook my popup up with maybe a slight rack with out it. If that makes sense..IMO The factory rake is a bit extreme.

Same. I had the rough country 1" spacer, and it leveled my Yukon nicely.

The touchscreen radio. There is an amazon link there for it.

Oh, i see it now.

And....... it doesn't work with Bose/NAV. None of them do.

I dunno. I have Bose and it's working through the front speakers/sub right now. I have to mess with it. I read a review about wiring it a certain way to get the rear speakers working. Still ironing out the bugs.

Looks like the navigation uses mapping apps from Play Store -- which app is it running and have you looked at any others?

I have it synced to my iPhone for right now. Not sure about all that you are speaking of. I haven't had time to mess with it yet. I just slapped it in real quick last night. I'm in the middle of an 11 day stretch of work with one day off Sunday.

So you're using the iPhone for the maps. The instructions seem to indicate that you can load maps to the unit -- I'm just curious about maps that work when the cell phone doesn't have the cell connection. Like out in the boonies with a real GPS.

They sell several different thicknesses of spacers for that. So if you want 2”of lift, buy 1” spacers etc. That Amazon link I provided, they sell them for 1/2”-2 1/2” of lift.

I'll check it out when I can read the manual.
