My Aventa LX was tight when I bought it, though it had loosened up a bit after three years, but still not to the point where the arms dropped to the ground. Then I had it overhauled due to an accident and it came back from Blue Ox really tight and it is still very tight two years and 12,000 miles later.
But I wouldn't worry about it touching the ground on its own, as long as it is actually sloppy at the big ball joint. BTW, Blue Ox does not recommend lubing the ball joint - it is supposed to be tight.
