Drop boxes or caster bushes

[@GUte]

"Effectively they are designed to achieve that flat radius arm from the factory mount by increasing the drop of the front half of the arm."

MR, they will still retain the same geometry as factory arms with correction bushes regardless of how you design the arm. You have to drop the rear. The main benefit of those arms is that you retain the OEM bush.

These arms that use the drop box help keep the line to factory depending on lift.
