    bigger brakes sometimes. and stiffer frame possible. just get the hd and have the full floater axle and be done with it.

    The HDs have a stronger, taller frame. That's needed to deal with the Alli and DMax clearance issues.

    And of course, there are heavier springs.

    IIRC, the 4x4 versions of 2500s use the 1/2 ton front end, while the 2500HDs use the same (larger and stronger) 1 ton front end.

    Definitely, the frame is the major difference
