Question:
Good morning, I am lookin at this air bag set up and my question is I am going to put a 3 1/2” lift on this truck 2021 gmc sierra 4wd diesel. I see you offer a 2”lift spacer but do you offer a 3 1/2” spacer? Thank you.

We need to go with a different suspension enhancement recommendation for you because air bag kits like the Firestone Ride-Rite Air Helper Springs # F2609 you're looking at won't fit with your 2021 GMC Sierra 1500 diesel - this is due to the air spring sitting up against the exhaust. When I reached out to my contact at Firestone he said they've heard of some dealers or shops modifying the exhaust hangers but the newer diesel models are few and far between so they're aren't any kits designed for it specifically.
As an alternative I recommend using the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS4611 because it still allows you to adjust the tension, so it's a good in-between option for adjustable air bags and non-adjustable jounce springs, plus you don't have to worry about this making contact with your exhaust.
