The first one I tried to install rolled the flange over trying to press it in, The second time I removed .5mm(0.02" or 1/64") from the diameter of the outer shell on a lathe, and about half that smoothing out machine marks in frame bores, it barely fit.
I also found that they set the control arms back over 1/4" so I cut the backs and shimmed the fronts to avoid all the extra work and cost that creates.
They seem to be of good quality materials and work well, they just need to be made to fit. But if I am to do it again, I'll buy the O.E.M brand or measure very carefully.
