So, I'm trying to justify lockers and went up into the Jemez Mountains where it's been wet and has some tough rock sections in certain areas and I just can't slow the TJ down, not one bit. I've never used my winch to rescue my self either, only a Hummer in the snow a couple of years ago. At this point the only real up-grade worth the investment might just be a sound system upgrade! Maybe a T-case shifter kit.
