I got a Q9000 on my JKU Sahara. With all my mods it weighs much more than stock and it's never had a problem pulling me out of mud pits that I've bottomed out on. I've also pulled about 20 different Jeeps and even a Chevy or two with it and it's never even hiccuped. It's Earned its spot on my front bumper for sure.
It's a Mud Marauder, not a Speed Demon.
