Just bought a 2018 Chevrolet Silverado Z71 with the factory 18" wheels and standard 265/65R18 tires. I was looking at the Rough Country 2" leveling kit/spacers. Just wanted to know if this works with factory wheels and tires, as their website recommends spacers for the wheels. Thanks. I did see a couple in here that were done just like I asked, but I just wanted to confirm.
