Tires scrub even with lift! Help plz

[Frankie21]

I have a 01 Z71 Tahoe with a 6" Superlift Suspension lift. I have 36x13.5 under it and my tires scrub like crazy! Its driving me insane to be honest. It's scrubbing so hard that its slowly pulling my front bumper down. The front sits a bit lower than the back. I want to solve the scrubbing issue but i want it to sit level as well. If i get a body lift how many inches will be enough to stop scrubbing? Will it make the leveling issue more obvious? And will i need to buy longer shocks or "struts"?
What do you guys recommend? I need help!
If you name a part could you please link me to it.
Thank you!

dumb question, but, have you tried trimming a bit?

 

[Frankie21]

Wow! Amazing looking truck man. Hopefully ill have one of those one day!

Are you referring to the black plastic in the wheel well? Then yes ive trimmed it alot.

 

[fco_gonzo]

Thank you. Yes I was referring to the black plastic. Two solutions, go with one size tires (35's) or change the wheels out. I don't recall the proper back spacing for that year tahoe but you can find it at your lift kit manufacturer's web site.

I just remembered your tahoe has torison bars have you tried giving them a couple of turns to bring the front end up.

I dont really want to go down in tire size. That would be my last resort.
What exactly is back spacing?
And i believe they've been turned a bit already, how can i tell if they have?
As you can tell im a newb. Sorry

You can get lift keys and get the front a little bit more up in the air to clear. You problem is probably related to backspacing and 13.5" tire. You may need to trim the bumper corners on the outside bottom edge. Do you having a 4.5" backspace or 5.5"?

Post up pics of the truck and where it is rubbing, it will help to give you more accurate answers.

Ive read about lift keys but don't quite understand it, what exactly do they do or how do they work?

Here you go. I also have a HUGE problem with the bumper. Why is it going down like that? Im guessing every time it scrubs it pulls it down a bit
