The HD package has a thicker frame in most configurations, which may or may not be of benefit long term. The shocks and springs are different as well, and they do ride a tad stiffer. But just an FYI on the axle ratings...... They are assembly ratings, and the HD currently comes with the same running gear, it is suspended differently, so it is essentially a "spring and shock capacity" rating. I believe the HD pac is not available on FX4's
