Question:
I am looking for a set of rear air lift air bags for my truck. I have a 2021 Chevrolet Silverado 1500 High Country 4WD 3.0 Duramax.

Expert Reply:
Since your 2021 Chevy Silverado 1500 has the diesel engine you're going to need the Air Lift LoadLifter 5000 Air Helper Springs item # AL57388. This is the only compatible kit. These air bags have a 5,000 lbs capacity that will level out the rear end of your Silverado when you are towing a trailer or hauling a heavy load. All mounting brackets and hardware are included for installation.
I have linked an installation video below so you can see how to get these air bags set up.
I recommend adding the Firestone Air Command item # F2610 to your truck. This onboard compressor will allow you to adjust the PSI in your air bags from your phone.
