Also keep in mind that when you beef up one part you will leave another more vulnerable. Thus the saying " Your truck is only as strong as it's weakest link." If you bash real hard or just have a bad landing keep in mind like TRD said the metal/aluminum will bend, and some will go beyond repair. With that too, whatever plastic that is attached to the metal parts i.e. bulkheads or shock towers they will snap as well. Thus leaving you with more costly repairs. I bash my nem pretty good with it being all stock and it was great that way, only problems I had was the axles at that time but CEN fixed that right up. Good luck, and I hope you find a good solution for your needs.
