I run ARB's F/R on the TJ. They work well, transparent on road and locked when you want off road. I have spent ALLOT of time in sand and they work. I run Detroit's F/R on both trucks and I love them, I know, I know, many many people will disagree. YES, I do spend allot of time in snow and ice, I am just used to them I guess. Tires on the TJ, 13.50x35x15, tires on both trucks are 38's, all are siped. Service truck will get 42's next time around, siped also.
