Yeah. There is no way these are just bump stops (They exist on the the front A arms of the VX). These "helpers" take the body and insulate it from the frame. Without them you're talking metal to metal contact between the frame and the body, and that means noise. If you study a VX underside you'll see rubber isolaters at all the mounting points. These spring helpers do just that, they help the spring and shock mounting points avoid a metal to metal ride in the rear. Renew yours and and you'll immediately hear the difference.
