Lift laws in SoCal?....lol- not likely. If you can fit it in your wheel well you're good to go- the CHP and locals have more fun chasing down the ricers and road racers than the F-350's with 44's and a full chrome underbody/suspension setup. Most of the Socal rigs are 2wd not necessarily by choice, it's harder to find a 4x4 in Socal- when I lived there I actually had to look to find a 4x4 or AWD car/truck. I wanted to by my Jeep there before I moved to NH to avoid rust issues, but it's a daunting task to find a 4x4 that hasn't been beat to hell and back on the trails.
I say keep the 4x4 and tow out the other mall cruisers from the trails when they get stuck. Better to have and not need than need and not have
