This particular truck is a Chevy Silverado 1500 GMT900 (2007.5-2011 Generation) We use Rough Country's leveling kit. It comes with all the hard wear that you need. You'll notice the truck is really clean...it's bran'new. Total time for this install..we did the pass side first, figured it out, then filmed the drivers side....total time...we took...about 1hr 15min.
