yeah you may have to take some material off the edge of the steering draglink to clear the large 1/8 scale rod ends on the UE stff. you can see what I'm talking about in this pic.

Also make sure you have the it installed correctly. if you have a rod end flipped backwards it will limit the travel because the rod's ball has a shoulder on one side but not on the other. Also I believe the instrucitons have more info on getting the full travel but dremeling the head of a screw down making the head a smaller diamater. try to move the suspension up and down and look to see where its binding around the rod ends and go from there.
