What was your best upgrade?

That's a tough question.  (the front switchable locker is my fave, was an arb, now a rubi 44 locker)

For me, it's the suspension tune with the right shocks and bump stops that makes it work pretty well.

snorkle, hands down... and i know trhat sounds stupid but if you have ever found a hole that was just a little too deep you will be glad you have one instead of buying a new engine.

umm seeing that I never did much to either JK I would say buying the JK that has a 4:1, lockers and the sway bar disco cause I am lazy  ;D

Man, I like everything I've done to my jeep so far. But, I would have to say my favorite is the 4.88's with both axles locked.

Either the v8 or the sas. I like them both... But I think the best will be fuel injection.

All my chit is high speed! And I have a feeling its just going to get better. The advice from a few of you guys has helped. I just wish I could drive it more.
