This is my post from Nov 2019 when I did my ReadyLift +2 inch lift kit
Ok guys, I did it. I installed the lift this weekend and my Trail Boss is noticeably higher up than it was stock. I am now running 35x12.5R20s on a total 4 inch lift. My rims are 20x9s with a 0 mm offset, however I added 1.5" spacers to stick the tires out even more. They sit about 3 inches past the fender line and it really balances out the truck nicely. Without the spacers there was a very minimal rub only at full lock. To run the spacers, I trimmed the first wall part of the mudflap (see pictures below) and with the spacers there is only a small touch at full lock now which I have no problem with. The truck rides fantastic, even better than stock and is super stable around turns. See below for pictures and before/after measurements. Best thing is I still fit in my car wash (monthly subscription) which has a 7 ft clearance. Parking garage wise I believe it will be tight fit, especially with speed bumps for the 7 ft ones but a 7' 6" garage should clear easily. As always, any questions just ask.
