The front suspension on my Oze chassis uses Chrysler upper screw-in ball joints, with the dimensions like a Moog K772. The ball joints that came with my chassis look like the cheapest thing that can be had, with rubber boots that don't look like they would ever seal well. In addition, the upper A-arm tilts quite a bit, while the lower is close to horizontal, at ride height. That causes the rubber boot on the upper to be squashed a lot, at ride height.

I'd like to try a Howe racing ball joint, with a longer stud, to raise the end of the upper arm. Some of these "racing" joints, like the QA1 models, say that they are NOT for street use. I notice that they have no rubber boots.

Anyone use a "racing" ball joint on their street driven car or have an opinion on this idea? Anyone know of a better ball joint?
