Finally, after a year of the Sierra, I traded up from a leveling kit to the ReadyLift SST lift. As of now, I currently have stock 20x9 wheels (SLT) and tires 275/60r20. Used a Authorized Dealer of ReadyLift in my local area. Dropped off at 1000 and picked up at 1730. Easy. Truck looks phenomenal, and rides just like stock, both in 2WD & 4WD. I do have questions though, 1: Anyone running 285/65r20 tires? I’m thinking K02’s, Duratracs, or the new Toyo AT3’s. On to the Pics.... This is in my 7’ parking garage. Fits perfectly. Also, I ordered a 21” antenna from The Antenna Source so it won’t drag on the beams. Sent from my iPhone using Tapatalk
