Ford F250 chassis from the 80's ?

[Olaf]

Is the king pin the same on all F250 and F350 chassis (1986)?

Olaf - Here's the info from the master parts catalog.

The first snippet shows that your truck takes the parts in parts list 30.1F or 30.1K, depending on when it was made.  And that both F250's and F350's use the same parts list.

But in the 2nd pair of snippets you can see that both of the lists use the same bushing kit, D5UZ 3110-B, and the same bushing and pin kit, E0TZ 3111-A.

So yes, both 1986 F250's and 350's use the same king pins.

Gary, FWIW, the operative detail seems to be "forged axle". I believe that the 2WD trucks all went to ball joints in 1987 with the possible exception of the F-Super Duty which had a beam axle and leaf springs.

Yep, I noticed the forged axles, which meant king pins.  Probably the same ones as on Darth.

You smart fellow, exactly the same, 1.054" diameter by 6.96" long.

Thank you all for your great help.
Then I'll order the King Pins and get to work.
I will definitely recommend your site.

Thanks for the info, Bill.

Olaf - Now you have the size and the part number for the kit.  Good luck!
