2009 GC Limited. 265 70 18 is the only change to date. Bought some Rubicon 17" wheels and put BFG M/T's on for hunting season OME HD Front, OME MD rear, winch to come, basket and lights bars first
Don't know about the 2010 5.7's, but the early ones don't have a forged rotating assembly, and can't handle (for very long) more than ~5-7 lbs. of boost. Personally I would never use forced induction on a stock 5.7 rotating assembly. Also, the $4000-6000+ price tag would keep me away. There's a Keene Bell blown WK SRT-8 that runs in the low 11's at our local strip. Really nice stuff, but oooohhhh the $$$.
