Hello everyone. First time poster here and also a noob about lifts. I'm about to pull the trigger on a 2010 Z71 Tahoe with an already installed 6" procomp lift. This will be my 3rd Tahoe but my first lifted one and I know very little about lifts. It's located almost 4 hours away from where I live so I had the dealer send me some videos of the lift/underside. It's located near the gulf coast so it has some rust on it. I'm aware ProComp isn't the first choice for lift kits, but what I'm hoping to get here is: Given that it's near the gulf, it looks like surface rust to me, what do you think? Any details you can tell from the pictures as to if the previous owner cut any corners on the lift install? Any tips if I do get this how to go about getting that rust off and sealing it to prevent further corrosion? In the top picture, on the right behind the tire tred is what looks like a super dry-rotted boot of some sort. WTF is that? Thanks so much in advance! Here's some screenshots I took: https://imgur.com/a/ZUeeg Again, I'm a complete noob about lifts and suspensions in general so any technical details please ELI5.
