Hello all, looking for some help here as I am relatively new to the aftermarket truck parts scene, I have a 2015 Sierra 1500 (4WD) w/o magneride, looking to have 4 inch BDS suspension lift installed, I know there will be a bit of underbody trimming and wheel well trimming required which I am not worried about, what I am worried about is if there will be a need for a longer driveshaft and if I will still be able to fit my stock 275/55/20 with a stock 27mm offset without hitting the UCAs
