Pick up any lexan guard and you should find it takes more of a beating... e13 Superchargers are strong and come in a ton of colors/configurations. I have a Gamut on my JET, it's light and sexy but I think you might break it pretty quickly on rocks. Alloy guards are preferred by some, I like the way the lexan guards suck up a bit of the impact and slide better, but your results may vary.
