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.

Hey, how did the Air Lift LoadLifter 5000 air bags work out on your Silverado? Did they help level things out when you were towing or carrying heavier loads? Your feedback could really help others setting up the same truck.
