What is wrong with the frame in the Jeep that you bought? If there isn't anything, I would stay with that unless you are going to have a full tube chasis built.

The difference between the long arms and short arms is obviously arm length, but what that means in terms of ride and flex... The longer arms are more parallel to the ground and therefore transfer the energy of a bump more vertically (or rather allow the springs to) as they swing in a larger arc, therefore making it closer to vertical as opposed to the short arms which become more vertical themselves as you lift your Jeep (or anything for that matter), transferring more of the force of a bump into the frame of the Jeep, giving you a more jarring ride. This also translates to more travel for the axles in off-road situations. Hope this at least gave you a start...

J-man, I think the train your thought was on jumped track... don't you mean a long arm will give you more travel/articulation off-road?

Potentially; yes - realistically, not without heavy mods. The suspension travel limit on TJs is not the length of the arms, it's the length of the shocks. However; it will keep the suspension geometry in better order throughout that range, and ultimately give a smoother ride.
