Yeah, it's detroit'd in the rear. I have a lockright for the front that I don't want to put in, and another front axle with an ARB that I'm considering putting in but so far it does what it needs to do given it's use and budget. I've taken it across the whole Spike trail without any problems, messed around on Hell's revenge, etc and it works well for those kind of trails. I may leave it alone, despite the fact that I'm really itching to build it the same as Wally before TTC. 37's, 6" total lift, custom springs, nice shocks, crossover steering, Doubler, bumpers, winch, cool motor and trans, cage, etc.
It would be fun but it does the job now, mostly since I have wally to do all the harder stuff.
It is weird driving the sub, I have to really pay attention or I drove over and into stuff with the rear of the truck.
