Question:
I have a 2020 2500 Chevy Silverado crew cab. It has 2 inch blocks in the back wondering if there’s anything I need to buy with the airbag. Pulling a fifth wheel trailer it sags a little bit, looking for airbag to help with the ride and level it out. If you could let me know. Thank you.

Hey George, thanks for reaching out!
You will need to add the 2" Spacer Kit # PB73VV Alpha HD Air Bag Suspension Kit # PB85RV if the distance from the bottom of your jounce to the top of the strike plate is more than 7-12", according to Pacbrake.
I also recommend checking out the Pacbrake Bravo Universal Wireless Air Spring Controls w/ Compressor and Remote # PB56MV so you get the best control of your air bags. This kit will allow you to monitor and adjust your air bags as needed on the fly. Whether you're 5th wheel towing, or just hauling a load in the truck bed, this kit will help make that easier.

Hey George, did you get a chance to install the air bag suspension and spacer kit on your Silverado? I'm curious to know if it helped with leveling out your truck while towing your fifth wheel. Your experience could really help others looking to improve their towing setup.
