Rear lift on a auto ride LTZ

[silverlx]

Hey guys I've got a 4x4 LTZ and the rear suspension really bothers me. It always looks like its sitting lower in the rear which I can't stand. I replaced the rear shocks recently with Arnott's reman units and they are pretty nice. I went with Bilstein 5100's in the front and they are sweet BUT my front end is now sitting about 3/4 inch higher (install is only 24 hrs old). Sounds great but it makes the rear look like it sagging even more. If the front end doesn't settle back down what are my options just to get about 1-2 inches in the rear without have to spend a bunch of cash and still having the nice ride?

Why did you remove the front autoride struts? That might be your problem there.

 

[silverlx]

I replaced the struts because they were both leaking. Now the front sits higher than it was before. The rears have the autoride but they dont raise the truck enough to balance it out.

I added a 1.5" rear spacer on my 4x4 LTZ avy so it would be leveled. Sounds like that's what you need. My rear end was sagging too due to a 2.5" leveling kit I installed up front.

So no problems with autoride? Im assuming its still rides just as it did? Can you post a couple pics from the side?

Is it a pretty sraight forward install? Support frame with jack stands and let rear end down. Springs just pop out them or do I need a compressor?

I guess what I'm getting at is that you didn't replace the front struts with autoride struts, correct? This might be the problem with your setup. I'm no expert in autoride, but I do know that autoride is for all four corners, not just the rear. If you put a non autoride strut in the front, I think this is going to effect the entire system.

The Bilstein 5100 front shocks lift the front end 1.75" if you install them with the spacers they came with.
That could be your issue.

Nope zero problems. My avalanche is an LTZ with AutoRide. Yea ill post pics later when on my computer. Not sure didn't do the install.

There are a couple different height settings, I have it set at factory height and its still got a lift.

The front struts/shocks only have the auto dampening. The rears have the air leveling system. The only difference in the Bilstein V the factory struts is the auto dampening feature. They should allow the truck to sit at factory spec height, at least according to Bilstein, that's why I'm puzzled...

so could i run the fabtech front spindles with a 2 inch rear spacer?

 

[silverlx]

I just installed the rear 1.5 " spacers. All was good for about 24 hours and now I get te service suspension light. Any ideas?

 

[felixgun]

Hmmmm that's odd. I have rear 1.5 spacers and an LTZ with AutoRide and no lights on dash... Weird.

Do u have a ccm kit?
I'm from lafayette and saw you the other day on Ambassador. Clean looking avalanche

 

[felixgun]

Nope the CCM kit is 2.5/1 -- I have the TGC 2.5 up front and a 1.5 rear billet spacer in the back. I needed more then 1" in the rear to get leveled since I have an LTZ and they sit lower in the rear due to the AutoRide rear shocks.

Haha awesome thanks. I was wondering if you were from this area when I saw your last name.

 

[wbreaux]

I have a ccm kit im waiting to put on and I'm ok with the 2.5/1 because I want a little bit of cali. Who did the work on your avalanche?

 

[felixgun]

A mobile mechanic in Denver Colorado did mine. I was there for a year for work and just moved back to Lafayette to work in the Gulf.

Just installed ccm on ltz suburban today with autoride. No problems at all, plug on front shocks stick right threw top of front spacer.

I dropped mine off at the shop this morning and I have to call when they open at 9. The CCM kit is in the back and they said they'd install it but we're saying they dont normally put the kit on auto ride vehicles so I seriously doubt they'll put the back on.
