: 2007 Rear Air Suspension Conversion To 5" Static Drop Aftermarket

Hey guys, I have a 2007 short wheelbase AWD Escalade.

My rear air suspension works fine, however, I am interested in converting it to a standard setup. But I'm not talking about an Arnott or Strutmaster conversion. I have a 5" rear drop new in box from my 2007 2WD Tahoe. Seeing what you guys think can be done to get this to go on. And I'm not trying to be cheap and make something work that shouldn't, I just want to get rid of my rear air anyways, as this is my third Escalade and I know one day it'll fail.

The rear five inch drop is achieved by lowering springs and rear axle relocators. It is McGaughys (#30012) 3/5 spindle drop. I've confirmed that the front end can be made to work.


Thoughts gentlemen?

It'll work. Yukon, Tahoe, Escalade... all the same platform. Some of each model have autoride, but all can be lowered with regular shocks and springs.

yeah familiar that they're the same platform, but what im wondering is what will need to be done; does the rear air suspension have different mounts for the springs since they are air-aided, will they need the non-air ride shock mounts ordered or mounting points punched out, etc etc. the small things; i know the kit can ultimately be made to fit, but what needs to be done.

and what about the air suspension components that remain; do you just cut power to the compressor and that's that?

In the rear, you still have shocks and springs on yours. Your shocks have air in them. So you'll replace them with aftermarket standard shocks and lowering springs.

Remove the fuse for the air ride so the compressor doesn't come on. Disconnect the front shock wiring and tie it up out of the way. Remove the rear air line and tie it out of the way

10-4 thats the piece of info i didnt know; didnt know if the rear air ride was done via air shocks, or air bags such as a mercedes s class. thats awesome.

last tech question; does the rear end of the escalade use the same diff as the tahoe, or is it a different rear end for the substantial power increase the tahoe has - the drop i have uses axle relocators.

and thanks for the help, your Yuk is SICK, thats the exact look i was going for on the Tahoe, this was my Hoe that the drop never made it on:

Looks good. and yes, same rear end as the other SUVs. The esky 6.2, trans and rear end were also avail in the denali and tahoe LTZ

yeah standard on denali and i think the LTZ had the option in 09. i was actually looking for one of those 2009 6.2 tahoes before i gave up and just got the escalade.

sounds good, im going to go over all of this with my GM master tech buddy and hopefully we can make it happen


PS i like the nice subtle touch of painting your D pillars color matched.

ive pretty much firmed up this will work, but i guess the one thing i didnt think about until now is if i do a 3/5 drop, itll be sitting lower in the rear, since the AWD sits level, whereas the 2wd tahoe and nathanjax's 2wd has a factory rake. damn

They make 1" and 2" spacers to put under the springs to raise it up

Just add those and it will be a 3/3

id rather cut coils in the front than lift in the rear; we're going down, not up haha :thumbsup:

me too. But that's the easiest. With my setup, I could go up to 4 inches in front. 2" spindles and then the struts coul be anywhere from 2" down to 2" up. I went all the way down (4") and my 24's sat on/inside the fenders. I have to keep adjusting till I could actually turn. It sits around 3.25" lower than stock. So I don't think you'll be able to go much lower than than in front and still be able to turn, unless you have skinny rims and tires on.

cool. was reading your post from 2009 in another thread about the air ride and disabling it so that the vehicle doesnt throw 'air ride' or service lights thinking the air ride isnt working (seeing how it wont be on there at all)

wheels are in the mail, and then this is happening. still looking for some input on how to disable the air ride so that no warnings or service lights display
