We use this F350 Tie Rod End in our crossover steering kits to mate up to the stock OBS pitman arm. It has 1"-18 RH threads and the smaller OBS Ford taper.
Includes: Tie Rod End, Castle Nut, Jam Nut, Cotter pin and Zerk Fitting.
Right hand thread only.
Note: Our steering arms all use the GM 1 TON Tie Rod Ends. This end is for the steering box side on 1980+ Fords
