I found one from a guy in NY that came out of a 1993 and he isnt 100% sure but says he thinks its a king pin style front? Does anyone know what year was the last year of these king pin axles that is 100%

Thanks Chris:D

I had a 93 F350 srw 4x4 and it had ball joints not the king pins. I don't know if the dually fronts were kig pin or not. Is it from a dually or srw truck ?

its a dually?

If it is a Dually then I would bet that it is still king. When I picked up my Dually 60 I was told that it was a 94 but don't know for sure and it is a king pin style front

I have a front d60 with kingpins out of a 94 f-350 single wheel. :D

My 60 is from a 93 SRW and it's ball-joints

I have a RCD60 from a 94 F-350 duallie, king pin.
You mean he can't tell the difference? I have two king pin style and one ball joint style, the difference is obvious.
The knuckle on the ball joint style has a castle nut on the top, king pin is flat with stamped cover w/ zerk fitting.
The inner knuckles (ball joint) have a larger opening top to bottom. If I was over at the shop, I could measure it and tell you more.
