Hi guys, I'm trying to identify what size lift I have on my 2000 nbs tahoe. Its a tough contry suspension lift . I bought the Tahoe with the kit already installed and I'm not aware how long it has been on there. Right now I have 305/55/20 tires on it and have a lot of wheel well left. Would there be a stamp somewhere on the lift that could have a part number? I have checked the Tuff country website and for my year and model, they have a 4 or 6 inch available. However, I doubt I have the most current version of they're lift kit on my tahoe. I will post a pic as well... Any ideas ?
