Found a deal on a FabTech 6" lift on Craigslist I couldn't pass up seeing how I was gonna wait until next year this way I saved about $900 ! Now I just gotta wait until I get the correct wheels before I can start the install which is a bummer. And I have never worked with a lift that uses only an add-a-leaf in the rear instead of blocks or a whole new leaf pack. I am worried about it not sitting level or sagging over time ? Anyone out there have issues with this on their FabTech system ? Thanks ! I'll keep ya posted !
