CALMINI also makes one:
CALMINI HD Track Bar

As far as the difference between the different bars, there probably isn't much. The geometry is barely affected by the change in length of the bar. Perhaps this difference in length is noticeable to some -- but perhaps there were other contributing factors with the suspension that seemed tightened up by the new bar. Personally I never noticed a difference between the stock bar and the DOR bar I ran once I broke mine. I did, however, feel that my Amigo handled far better lifted (even with the stock bar) than it did stock...

Anyway, so you know, the bar doesn't break because of the lift -- it breaks because the stock bar is a total piece of garbage. Ding it on a rock or two and it's shot. You could probably get under there and bend it with your foot if you tried.

Also, so you know... The truck is *driveable* without the bar, so if you break it on the trail, you can get home without it. This is in no way shape or form safe or recommended, but it can be done. I did exactly that -- except the trail was in Colorado and as you know I live in New Jersey. <img src="/forums/images/graemlins/wink.gif" alt="" /> Drove it all the way home that way, kinda scary, but I got used to it. I do believe that was around the same time that Kevin dubbed it "The Wet Marshmallow" tho, due to the way it handled on the street... Picture yourself sitting behind the wheel of, well... a wet marshmallow. <img src="/forums/images/graemlins/wink.gif" alt="" />
