Hemidenny K member club?
the ones that come in the box with the ball joint (Moog) are the ones I have always used. I will agree, they are not the best fitting, but they have always held the grease in and kept the dust out.
I even experimented with the Energy Suspension boots mentioned in another thread, but the ones that come with the ball joint seem to give more overall coverage of the ball joint. I try not to to do anything on the cheap and only want what works the best.
what application are the ones you ended up with?
