Hey Sean, that's quite the lift. The 6" Lift Spacers for Firestone Ride-Rite Air Helper Springs item # F2375 are going to be our tallest option. There's no spacer that will help you out with a 9" rear lift. They are compatible with the Firestone Ride-Rite Air Helper Springs item # F2430 that fit your 2018 Chevy Silverado 1500. These will attach directly to your bump stop perk and to your axle on the inside of your leaf spring pack.

Most lift kits don't actually raise the rear end the same distance they're advertised. I've got a Silverado with a 3-1/2" lift leveling kit and they only put a 1" block in the rear between the bed and the frame.

How tall is the rear lift on your truck and how did they raise it? I'm worried about compatibility as well as the distance. If you could add the information below where it says ADD comment, I can give you a yes or no on adding air bags. Also if you want me to take a look at your rear suspension to see if there's going to be any interference with the brackets on the item # F2430 kit you can email any pics you have directly to the email address you receive this response from.

They used a 5 3/4 block with “1.5” add a leaf. The spacing from the bump stop cup lip to the flat mount on axle is 12”

@SeanL Oh made it by 1/2"! The The 6" Lift Spacers item # F2375 and the Firestone Ride-Rite item # F2430 will indeed work with a 12" gap. I recommend looking at the installation instructions for the Firestone Ride-Rite item # F2430 before you purchase the air bag system to make sure there's nothing aftermarket that's been mounted in the way. They are linked below. I also 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.
