As long as you’re not using stock wheels you’ll be fine. 2018 GMC Z71 4X4, Crew Cab Standard Bed, I put 275/60/20 BFG KO2’s on with a 2 1/4” level up front and added 1” rear then threw the BFG’s on stock wheels only to get both upper left and right UCA’s rubbing. Apparently, the level caused the UCA’s to have different angle causing the rub. I fixed it with new Fuel wheels with plus 18 offset. All good now! Sent from my iPhone using Tapatalk
