Haha. Must be some weird thing in the Japanese to English translation. Yeah those are the bumpstops as the rest of the world calls them. If you are riding on them 24/7 once again I would look at your springs/shocks. Many members here claim they are riding on their bumpstops but they are really only intended to "help" the springs on extreme up travel (as we all have already expressed) so that you do not "bottom out" so rough, or to smooth out suspension compression, or for those of us with larger tires it keeps the top of the tire from contacting the cladding on up travel.
Hope this link helps clear it up:

These are the bumpstops that most everyone here that has done a lift and Tire upgrade have replaced the old bumpstops with:

Quote from website: "bump stops help cushion your suspension, preventing bottoming-out and the extensive damage that can result from doing so..... Larger competition style universal bump stops smooth out suspension compression and have a large reinforced metal plate welded to the mounting plate and molded-into the bump stop itself."
