Hi all,

A lot of people have been wondering if rear load-leveling suspension on their first gen Equinox is possible, and, if so, what shocks to use.
It actually is possible and it depends on which brand you prefer.

Usually, if anyone does a web search for air-suspension for their Theta Platform vehicle, they are usually slapped with a ton of air-spring recommendations because it is actually unknown which air-shocks can be used, even though they are still manufactured, but, listed for other applications.

Why air-shocks over air-springs?

Unfortunately, your vehicle’s rear springs are technically in a debris path, and, air-springs have a tendency not to last as long, and/or get damaged because of this. They are also more prone to blowout under a heavy load. On top of all this, air-springs are actually harder to install and/or replace on the Theta Platform than air-shocks. In fact, you can even replace the air-shocks without removing the tires. The air-shocks also last longer than standard shocks and air-springs.

Why use an OEM system?

There are a ton of after-market systems out there that can be used for this application, however, they can also be rather costly, and, may not give you as many options. GM/Delphi actually makes a ton of OEM solutions that can actually fit and be used on the Theta Platform, that, if you have a good junk-yard, can be rather cheap to find and install. Typical LKQ Pick-Your-Part pricing is $35 to $40 for the system, and, shocks, even though after market, are typically $60 to $80 for the pair depending on brand and where you purchase them. Plus, typically with the OEM option, you have a choice over whether or not you want to add the inflator port option, and, rear power outlet option as well.


Attached is a complete manual from beginning to end in Adobe PDF format because it is too long to post in a forum post. By the way, I did write the entire manual all by myself based on my experience.

Including a few pictures of how the sensor should look as well.....



Hope you all enjoy.

Thank you,

Starflare5.

An additional note: Found out that this does actually increase the towing capacity quite a bit. Was able to tow a full 6'x12' UHaul trailer across 1200 miles and through mountain passes with this installed.....
