Rancho just makes the Add-A-Leaf (AAL) system. I don't think there's a difference. You can get the AAL system from EOE- Todd makes stuff specifically for the X/Frontier. The link is
here . As for raising the front end, the T-Bars is the poor-man's lift. While, yes, it does cosmetically raise the front, you will lose a little of the droop that you would normally have. I think the A-Arms are the part to replace to lift it up for real. Correct me if I'm wrong guys/gals.
