The doo's are setup good to go from the factory. I would do some research on the gnr braces. I run them, however a few people think if you overbrace something, something else maybe more important and expensive will bend instead. I smoked a rock pretty good last year, flew of my sled and everything, to my suprise a-arms, s module, everything looked great and nothing was bent. So I personally think they are worth it.
Other than that, skinny skid plate is a good idea I think, and a aftermarket front bumper. Stock bumper is thin as tin foil, and will crinkle if you run into a tree at 1mph.
If your looking to drop some weight by getting a can, lot of people like hps.
