Couple items to note about the stock bumper style swing arms:
Spare Tire: You will have to remove your spare tire BEFORE you install the swing arm OR you will have to modify the swing arm mounting bracket (drill a large hole) so you have access to the tire lift/drop crank hole. It is a nice and capable unit but certainly not as stout as the arms integrated into the full bumper. Make sure to spec the correct bolt pattern when ordering (8 x 6.5 or 8 x 170mm) for the tire mounting plate.
Box Swing Arm: Also a capable unit but will not handle the heavier loads of the integrated bumper swing arms. This is becasue the stand aloane swing arms do not have the extra tube that wraps around back down to the sides of the bumper.
Nice adds though!
