Installed on my 1997 F-350 4x4 7.3L. Fits great, seems good quality. installation warning word. The sockets are manufactured to be clamped into hangers/mounts. This compression comes from the bolt, which requires a lot of torque. UNLESS you are strong above average and creative with a large torque wrench, you won't be able to install them without a hoist. The reason I had to replace mine was because the last guy thought "tight" was good enough. It never happened and almost never happened.
