..I'm going to take measurements somewhere else but can someone explain to me exactly how the ZW7 functions and if it could be an issue or not? The instructions for the suspension Maxx 1.5 kit only say to look for Z55 or Z95.
@MikeK1981 -> the rig's looking great! Like that you kept the chrome lugs with the chrome trim.

Still having that lean issue? I've certainly read about this before on the TYForum, but found a nice little article on the web regarding "ISSUES W/ GM ZW7 Suspension".
Take a look: https://vroomo.co.uk/gm-zw7-suspension-issues/
I'm guessing that you have not thrown any codes because you didn't change the rear suspension (I believe) and the vehicle is NOT equipped with rear air shocks. From reading this article, it sounds like the rear shock absorber needs to be replaced. Has your dealer or mechanic checked this in the past 6 months?

Keep us posted. Amazing what a difference a little chin up, LT tires and a moustache trim will do, huh? Well done!

Thank you, I'm very happy with it! And the lean issue was just my driveway tweaking the supsension slightly i guess. I checked it at my in law's and it's perfect. I've had thoughts about doing the black grill, but the reason I left the suburban badges was because I still had the chrome lugs with the chrome bow ties so it all kind of flows together I think, even though I blacked out the trim and pulled the LT badges. Cleaned it up without going all black everything.

Thank you!
And correct, no spacer or lift in the rear.
And they’re the stock wheels that I had powdercoated satin black, yes.

Hi again @Jeff_ , or anyone else...I finally got my Bilsteins in last month and got around to taking it in to the shop today. Just got a call from them asking if I knew that the current set up is "air ride?" I said I wasn't necessarily aware, I just knew it didn't have the Magneride, which I've read can cause it's own issues when installing any sort of lift, but hadn't read anything that would affect putting Bilsteins on my 2018 Suburban LS 4WD.

They said they could try to put them on, but it would probably throw codes or otherwise. I'm not the most mechanically inclined (hence having a shop do the install), but I guess I don't really know if they're just confused, or if my setup would require something different? Thanks for any guidance.

FYI, this is the same shop I had install Bilstein 5100s (that I supplied) on my 4Runner about 4 years ago.

As long as they are just messing with the front i would think that everything will be just fine. The air ride is just for the rear of the vehicle. MRC is in the rear AND the front.

@MTDreamin - can you post up your GM RPO Sticker? (codes on sticker in glove box)
With that, we can get a look at your OE suspension. I agree with @olyelr that only the REAR shocks would have the air ride. And the ZW7 does NOT use external air pressure...

I'm assuming the Bilstein shocks you purchased are for the front suspension, correct?
Do you have the Bilstein part#?
Are you keeping the front leveling kit with the new front shocks?

Thanks for the replies @Oh Kee Pah and @olyelr. I will grab my RPO sticker this evening and report back.

I did actually buy both the front and rear Bilsteins and was intending to have all 4 installed, though the fronts were the important ones. I did/do not have any additional front leveling kit at this point, was just planning to use the front height adjustable Bilsteins to achieve that, as @Jeff_ had done in this thread, and I did previously on a 4Runner. But just figured I'd do all 4 to match at the same time.

Here are the links and part #s. I ended up ordering the fronts and rears from different sites based on stock availability at the time.

Front
Mfg Part #:24-253253

Rear
Mfg Part #:24-253260

After having written the below, I just found reference of the air leveling suspension with regard to the max trailering package. Is that what I was missing, that the max trailer package has the air leveling and without does not? Because mine does have the max trailer package. Thanks again for any insights.

What I still don't understand is, after entering my year, make, model, trim and drivetrain, that multiple websites said, "Yes, this fits your vehicle," including on the rears. I now see the caveat, "Without Air Leveling Suspension" (specifically for the rears), but do all of these Suburbans/Tahoes regardless of trim have this "air leveling suspension", and if so, why would any show that they work or are compatible? Again, at this point I'm just interested in making sure I can get the front done, but I'm also hoping I can educate myself enough for a discussion with offroadwarehouse to make sure I can get a full refund still now that the return period has ended. This is for the rears:

Your factory rears are air shocks, those are not. They will not work unless you delete the rest of that stuff.
