Have had the AT4 since Jan 2019, and love everything about it. 2 weeks ago finally got some new rubber for it. Wish I had done on day one, truck feels so much more planted to the road, rides even better and looks better. Went with BF KO2 285/65/20, no rub at all and did no mods. Now to decide if I had the RC 2in level to it, have it just havent done yet. If do the level might add new blocks in rear to keep some rake.
