Grand Cherokee TrailHawk was made for only one year, 2013. Then reappeared a couple of years later with less off road equipment. I got the lower diff gears, the rear axle is a electro/hydraulic diff. Going from 20% lock to 95% lock. You never feel it doing it's thing. Rockrails were standard equipment, now they are an option. The whole belly is skid plate, the later years is an option. Basically all the off road equipment that was standard in 2013, is an option on the later years. I've done some 4wheeling with it out in Colorado, NM, and around home.

Odd. My 2010 had all that stuff plus ELSD up front, and 0-100% lock. Seems they nerfed them every year after 2010 with regard to offroad stuff.
