When you purchase your Nitro Rustler roll cage you will need these things handy. Some Hex Drivers or Allen Wrenches, Loctite, and a little patience to read through all of the directions supplied with your purchase to assemble your roll cage. The supplied directions are in full color, great detail and will seem like installing the cage a breeze. If you choose not to use Loctite the screws will rattle loose and fall out. I experienced this myself.
