Recommended Suspension Enhancement For Towing with 2009 Chevy Avalanche LTZ

I may have a solution for you, but it does not appear that there are any true air bag kits available for the 2009 Chevy Avalanche LTZ; from what I can find with some research it appears that most of these models have a shock and coil suspension and not a leaf spring suspension system. You could use the Air Lift 1000 Air Helper Springs for Coil Springs - Rear # AL60769, but these are designed for coil spring systems, so it would not work if you've got leaf springs. The Air Lift WirelessONE Compressor System for Air Helper Springs - Remote - Bluetooth - EZ Mount # AL25980EZ would be the best wireless solution for a compressor to work with these bags since it comes with a wireless remote to allow you to fill and deflate the bags from the comfort of your truck's cab.

The best solution we have available for your truck with leaf springs would be to use a Timbren jounce style spring like the # TGMRYS4 which will do the same job of helping stabilize the rear of the vehicle and prevent sag when towing a camper. Timbren systems do a great job of absorbing road shock and become more rigid as more weight is applied, so it won't effect your ride quality when you're not towing.

I've linked a review and installation video of these springs for you to have a look at, but this would be the best solution available since we do not have a custom air bag kit for your 2009 Avalanche.
