Upstop is almost never used.
Oops, I should read better
Did you mean upstops, Rodrigo? Upstops aren't usually used - I've never had to use them, at least.
Upstops are the screws which limit how far the suspension arms move in an upwards direction.
Downstops limit the suspension arm's downwards travel.
