Good morning all,

I'm new to the site, and new to the SUV world as we just purchased a 2011 Chevy Suburban LTZ. I have had a 2005 Sierra 1500 for 11 years now, so I'm used to GM and the basic platform, but have some questions about the air suspension that these have.

Based on some things i've read, the LTZ trim model comes standard with an air shock with two possible options. Simply the air shock that just allows for a nicer ride, or an auto level option to the air shock? My question is, how do I know which one i have on mine?

We tow a 7,000# trailer, so i'm looking to order the additional air shock that fits in the coil spring to help level out the truck under load, and to add additional support to the auto level as i've heard these are not cheap to replace.

Secondly, Has anyone utilized the air coil spring helper and hooked it up to the existing air pump? Is it even possible to do?

Thanks,
Brian
