Replacement air bag looks different....
 

I ordered a replacement airbag for my 98 GMC. These are helper bags, not main suspension bags. The kit that came for this truck had bags that didn't fit and needed to be exchanged years ago when first installed. I went threw my receipts and thought I ordered the correct part number this time around but the bags look slightly different. Is this because ones been fully inflated and used for a few years or does it look like I got the wrong replacement bag? Air lift's website no longer has email contact for me to ask them this directly :censored:

Tough call..... I'd say they're close enough that I'd agree w/your conclusion (used/inflated slightly tweaking the visual). Overall, they look to be similar as far as height & OD.
