One of our favorite attributes of the new Chevy trucks is the fact that the 2WD and 4WD half-ton rigs use a similar suspension. Not only did this make it easier on the aftermarket parts manufacturers that develop suspension kits, it also made it easier on installers (like you) who choose to modify the trucks. With the new strut and A-arm design that Chevy uses, the same steps are taken on both the 2WD and 4WD trucks when adding a few inches of spacer lift.
Rough Country has this new 3-inch kit that addresses both the front and back end of the truck to allow you the fitment of 33-inch tires on either a 2WD or 4WD 2007-to-current Chevy 1500 Silverado truck. The only difference in applications is the addition of two front differential spacers to keep your CV shafts at the correct angles.
We stood by and twiddled our thumbs (it's nice to watch other work once in a while!) while OC Tranny in Costa Mesa, California, got this kit on in a few hours.
Though we didn't attempt this one personally, we'd feel confident trying this at home as long as we had a few good jackstands and a floor jack.
