Question:
I just received my 2709 Firestone kit for my 2020 Chevy Dually. Problem is I didnt account for a 4inch spacer thats needed. What spacer can I use for this kit?

Expert Reply:
Hey Mike, welcome back! Glad you received your Firestone Air Bags item # F2709. For a pair of 4" spacers you'll need the Firestone item # F2370. These are designed for trucks that have a 4" lift in the rear end. They're going to bolt directly to your air bags and brackets with the included hardware.
How tall is the lift in the rear of your Silverado? If you have a 4" lift on your truck it's most likely going to be quite a bit shorter in the rear.
