These are the front and rear upper A-arm drop brackets. As their name implies, they drop the upper A-arms, thus creating lift. They are made from 1/4-inch steel. Look closely and you can see where items like the OE extended-stop support wing and part of the upper control arm pocket were removed using a plasma cutter. All total, there are approximately six OE items that need to be removed or modified to make room for the new suspension components.
