No not the bumper, unless you have aftermarket steel winch bumpers or something gnarly. You might damage the stock bumpers. As SR1355 stated tow hooks are a better option. Like I said metal to metal jack points attached to frame only. Be careful. High jacks can be dangerous. Keep in mind when you are jacking something up from the front or rear it moves up on an arc thus pulling the top of the jack away from you ever so slightly, but sometimes enough to tip the jack. Be sure to always chalk tires and set brakes. Seriously, in 10 years of offroading I have used my high lift maybe 6 times, and that was in the desert when I was stuck by myself and couldnt get a tug out. Had to jack up the car and wedge stuff under the tires. Some people use it more then others, I try not too. Although the day you forget to pack it, you'll need it.
