If you are looking to add style and substance to your phat ride, why step when you can nerf? Nerf bars are a styling step above your standard step bar. And they look way fly (or is it phly?). Since tubular nerf bars are a lot longer than most steps, one bar on a three- or four-door pickup, van or SUV can provide an step up for people getting into the front and/or rear door. But that's not all. Nerf bars can protect your vehicle's paint job from careless car door openers in parking lots.
