This is the complete rear end removed from an F150 7700 series pick up truck. These were commonly known as a “heavy half” since they are heavier duty than the standard half ton axle found in standard F150 trucks. This is the same rear end/ differential found in 98 and 99 F250 light duty pickups and is. Considered to be equivalent to 3/4 ton. The rear brakes are disc rather than drum as in the regular F150, the differential itself is bigger and heavier duty (I believe it is the same as the F250 super duty differential but this is something you need to verify on your own). It has an extra leaf compared to the standard F150. The wheels are 7 lug. I cannot keep this at my home due to a homeowners association so it must sell today or I will take a few key parts off of it and scrap the rest. Great upgrade for an F150 or replacement for an F150 7700 or F250 light duty, or a perfect axle for a trailer.
