Got everything I need to level my 2017 Silverado 1500. Eibach stage 1 pro truck lift and dirt king upper control arms. I'm having a hard time decided on wheels because on dirt kings site you have to have a max of 4.75" of backspacing, yet when I emailed them they said 4". Also seen a guy on YouTube clear them with the stock 20" wheels with no spacers. I currently have the 18" wheels with 275 bridgestones. I'm not crazy about huge wheels and massive offset and just want to see if anyone else is running Dirt King uppers and can give me some insight.
