Somebody a few posts back mentioned they maybe didn't like the new shock caps.
I think they are really nice if for only one reason. You will be able to change shock positions on the tower much faster. Before you had to pull the retaining nut, remove the plastic spacer washer and mount, then you had to remove the post. Now you just move the ball stud. Easy.
I am assuming the caps are molded so if things get loose after awhile just replace them as a consumable. Before you could only get the plastic mount pieces in U3937, which had things you didn't even need (spring retainers) so the price should be roughly equivalent.
