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.

That's the best way to do the rear auto-ride sensor rods; 10-24 stainless machine screws cut to length. And yes you're absolutely right it's just a trial and error game to dial in the correct length on each side. I've always ended up with different lengths in the rear for passenger side vs driver side to get rid of the factory uneven "GM Lean" these all seem to have. My '13 Escalade ESV was exactly 1/2" shorter ride height on the driver side from the factory

you are aware that the rear shocks are "looped" together with 1 airline correct? one shock is not going to sit different than the other. one may "activate" on a bump different than the other if the sensor rod was different length but it's not going to affect ride height. It can't inflate more or less than the other side.
when sitting parked there is "0" activation and psi is equalized at all times.
the lean would need to be adjusted differently

Wes is correct. There’s only one airline, it runs off a T from the compressor. There’s no way to have different pressure side to side. My bagged Silverado was initially set up with the same idea and since the bags were 100% of the suspension at all 4 corners with no shocks or springs it would lean in the corners. I replumbed it and added an Airlift computerized manifold that actually shifts more air pressure to the outside bags in a lean so now it stays level no matter what and no matter how hard I corner. But you can’t do that to one of these trucks with the factory setup.

I was going to add the 2021+ now have a manifold but this generation of trucks does not

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

I think I'm gonna buy it. The link has two versions: one for a Silverado, and one for a Yukon. I assume you got the Yukon version, yes?

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.

Can you share which Maestro harness would work? All I'm seeing is 2014+ stuff.

I don't recall, unfortunately. But Crutchfield has a configurator that brings up several options: https://www.crutchfield.com/g_103000/Radio-replacement-interfaces-harnesses.html?tp=2977

And there is a good, though ancient, thread on it here also: https://www.tahoeyukonforum.com/threads/adding-an-aftermarket-radio-to-07-14-faq.77180/

Thanks.

It'd be cool, and helpful is someone would aggregate a 2025 updated thread, with part numbers.

Yeah well you would still have to hack into the OS of GM’s system or add your own aftermarket system. I doubt it would be worth it in order to get rid of 1/4- 1/2” of lean.
