Mar 30, 2009 · For my 3" body lift and these 33s on a gmt900, I had to trim the plastic AND use zip ties to pull the liner back as far as it would go. If I just tried to pull the liner back they would still rub when turning the wheel. My wheels are only 9 wide with 5.7" backspace too. I'd need more than 3" if I went with 5.0 backspace without a doubt.

Feb 23, 2021 · Anyone else building GMT900’s? I’m potentially looking at a 2013 Tahoe for ski trips and glamping mobile. Very keen on one that’s for sale—nice color and Z71 package. Only mods it’ll get are small lift, 33’s, full length roof rack, and a dongle to deactivate AFM.
