2012 Avalanche Suspension Air Bags

[Freeskiken]

I have a 2012 AV Z71 4X4 LT. I tried to order airbags today but the company replied and said they would not fit my truck. So I am in the process of trying to cancel my order. I ordered Firestone 4108 ?

I bought a new to me 2016 Fun Finder 229 VSD trailer. It is 26.5' long, 5,200 lbs, Tongue weight 1,000 lbs.

Also bought a Curt TruTrack Weight Distribution hitch, 10,000 lb.

Can someone tell me what air bags will fit my springs in my truck ?

With the Firestones it all comes down to whether you have the autoride option or not?? With AR you'd need a 4186, w/o AR the 4108...

This AirLift catalog explains what/where to measure to ensure they will fit on page 20

Edit: If you have AR and ever need to replace your compressor I strongly recommend upgrading to one with higher amperage and more psi.... I went from 25A to 35A and up 100psi.. night and day

Hi, Thank you for the reply. I ordered some from Amazon and I ordered the 4108 kit. I sent them a message to see if it would fit my truck. They replied that it would not fit a 2012 ? So I ordered a set from a local truck parts supplier and I see they ordered the 4186 kit. So I just sent them a message to say these fit a Avalanche with the autoride feature. I thought the 4108 kit was correct. Hopefully I can get the right ones.
