Be careful in purchasing used Advance Design rear bumper braces! Even the seller may not know there are two different shapes. When installed incorrectly, the rear bumper will not be in the correct position.
The more common rear braces are on the half ton pickup. They are designed to lower the long horizontal bumper so the tailgate can swing down as much as possible to be protected from backing too close to a loading dock.
The other rear brace design is found on the Suburban and Panel truck. It lowers the bumper just enough to clear the Panel truck and Suburban double side-by-side swing open doors.
At first glance, these two look almost identical, but the photo below shows the difference. Each set of rear braces are on edge, touching to make a pair for this photo.
