x4 or 7 or whatever...don't heat and bend.
one thing that hasn't been mentioned is that you'd not only be weakening it, but also wouldn't get the proper geometry. a raised arm is actually a longer piece of metal since it has to make the bigger vertical distance while maintaining stock horizontal distance.
i can be cheap, but steering is not a place to scrimp. on the other hand, if you save that $50, use the heated/bent arm and roll the truck, you can put that money towards installing a 14bolt ff on your new motorized wheelchair. better parking, too.
