Brushgaurds are great for going off trail, and smashing through some bushes. Hit something substantian, and it will push back, breaking your lights, bezel, and other plastic parts.
A real bumper will protect the weak fiberglass bezel and front end of your jeep, while also allowing you to slide up and around rocks. ALSO, it will tie into the body, making it strong enough to be used as an anchor point.
I'm running a trimmed factory bumper, and I scraped it and cracked the caps hitting rocks.
Go to jcroffroad.com and check out the stage 3 bumper.
