Hey guys. I just bought a used 09 Silverado 1500 2wd extended cab. It looks leveled ... and kinda low. It has stock 17" Chevy wheels and 265/70 tires. I just measured from the ground to the center of the lower part of the wheel well. The front measures 36 1/2" and the back 37 1/2". I don't see any mods to the leafs or blocks. Any one have this truck and/or know the factory height? I wanted to do a 2.5" x 1" level kit and put on 31-33" tires on 20s.
