Recommended Air Bag Suspension for a 2021 GMC Sierra 1500 w/ a 4" Lift
Question:
2021 GMC Sierra 1500 4wd SLT. 4 inch BDS Suspension lift Looking to purchase rear air bags. What do I need?
asked by: Josh
Expert Reply:
Since your 2021 GMC Sierra 1500 has a 4" suspension lift you most likely only have a 3" block on the back axle. With this in mind I recommend the Firestone Ride-Rite Air Helper Springs item # F2609. This system has a 5,000 lbs load leveling capacity.
You will also need the 3" Lift Spacers for Firestone Ride-Rite Air Helper Springs item # F2367.
I recommend adding the Firestone Air Command I item # F2097. This onboard compressor will allow you to adjust the PSI in your air bags from the comfort of your cab.
