Ok this tut By AznKevin4eva (Azn Pryde!) will show you how to lift your truck about a inch or so.

Materials:

4 Long screws
Xmod (der...)
3 small nuts
Glue
Screwdriver

First remove your front body mount. When you are done removing it you should see a piece of plastic sticking out in the middle near the shocks.
The piece of plastic:

Its the one that secures your body mount on the top

Second put your body mount on that piece of plastic and use the long screws to mount it on like this:

Third take off your entire rear mount assembly including the black part. Now at each screw mount glue a nut to the mount like this:

Now reasemble it after glue is dry.

Put everything back together and your car should be taller and looking more agressive. Enjoy that mean xmod truck you made. Here is my truck raised:

I hope I get a sticky for this :D
