Hello everyone, I have a 2018 Silverado Ltz Z71. Currently has stock 20s on it. I have a 2.5 Inch leveling kit with add a leaf in the rear form Auto Spring, as well ordered a set of Bilstein 5100 for the front to swap out. Id like to run a set of Trail boss rims on my truck, preferably 18s but would run the 20s if i have to. I have had a few people recommend me to run new upper control arms due to the lift. Anyone have recommendations on Ucas? I'm planning on running 275/70r18 or 275/60r20 depending on rim size. I'm relatively new to backspacing/offset stuff. Looking at different Uca's most say you cant run stock rims with some others make no mention. Thanks for the help everyone.
