Nope....just call, and only order the UCA's. They're about $160USD shipped.
Ryan.... The issue with the balljoint is not that it will travel past where they were engineered to go, the issue is that they sit at one extreme of their travel, the entire time. That not only puts stress on the ball joint itself, as it was designed to be straight, and only venture to it's extremes with suspension travel. THe other thing is, that the boots on them will wear out faster, as one side is completely squished, and the other extended. As you know, when the boot rips, the ball joints fail shortly thereafter.
Another thing to consider....with the age of our trucks.....I'd say it's more than possible that things move differently (read: more; further) than they did initially from the factory. Bump stops wear down, get squished. It may only be a small amount of difference, but if the ball joint is already sitting in at an extreme angle, this could be an issue.
