Doing a body lift without all the extensions, and without raising the bumpers and without at least attempting to hide some of the frame looks like shit. Thats what gives body lifts a bad reputation, people who do it half ass and dont pay attention to details and make it unsafe.
Get gap guards. Or make some. Paint your frame and get some nerf bars. Adjust the height of the nerf bars so they dont hang too low. Or better yet, get some n-fabs. Raise your front and rear bumper, and either re-install your tow hooks with spacers or flipped, and get a valance to hide the front frame horns. Paint your trailer hitch or remove it because it will hang low, and theres not much you can do about it.
The 2 door and 4 door rear bumper mounts are different. The rear body mount on the 2 doors interfere with any bracket made for a 4 door tahoe. Zone Off Road sells rear bumper relocator brackets, but on their site it clearly states that they will only work on 4 door tahoes. You have to cut the brackets and modify them for them to work on a 2 door.
I usually dont post like this, but I dont want the OP to have a bunch of wrong information. I researched all these things before I decided to do a body lift. If you pay attention to the details it can look good. Don't just slap the kit on there and call it good, cause it won't look that way.
