Question:

I have a 2024 AT4x. I bought the air lift AL57388. But I added a Peak Suspension 2inch front and 1inch rear lift to the truck. So I replaced the factory 2inch blocks with 3inch blocks. Airlift does not sell a 1inch spacer. Will the 2inch spacer work? Or should I not worry about adding a spacer to the AL57388 kit?

Hello Eric, thanks for reaching out. Since you only installed a 1" lift on the rear of your 2024 GMC 1500 AT4X, you should not need an additional spacer. In order to confirm this, you will need to measure the distance between the two air bag brackets once installed and then subtract the height of the air bag. If the difference is 1" or less you will not need a spacer. If the gap is more than 1" you will want to add the spacers part # AL52420.

What should the “normal height” of the airbag be when deflated?

@EricM The air bag height can differ depending on what kit you have. The # AL57388 kit uses the air bag part 58439 which is listed at 5-1/2" tall at normal height.
