This is a full kingpin kit for the Meritor/Rockwell 460 series steer axle - kingpins, bushings, thrust bearings, seals, and the hardware to put a knuckle back together right. Ford ran this axle under the C600 from about 1980 to 1986, so if you've got one of those trucks still working for a living, this is the kit that goes in it.
Kingpins wear out from the top down usually - you get play in the knuckle, uneven tire wear on the steers, or a truck that wanders at highway speed and won't track straight no matter how much you fight the alignment. If the old pins are scored or the bushings are hammered out oversize, this kit replaces the wear parts so the knuckle pivots tight again.
It's not a drop-in for every steer axle Ford ever bolted under a C-series - it's specific to the 460.166C axle housing. Different years and different axle suppliers used different kingpin diameters and thrust bearing setups, so this kit matters more than the truck's model year does.
R201312, 460.166C, 597258C91, R200198, 01R201312 - these all point back to the same Meritor kingpin kit design, just stamped by different catalogs (Meritor's own number, International's 597258C91 since IH used the same axle in some applications, and the aftermarket R-series numbers). The 2036352 you'll sometimes see is another old reference for this same build.
What actually varies between kingpin kits that look similar: pin diameter and length, bushing bore size, and whether the thrust bearing is a tapered roller or flat washer style. Get any of those wrong and the knuckle either binds up or has slop in it from day one - no amount of grease fixes a kit that's the wrong diameter.
Surest way to confirm before you order: pull the old kingpin out and measure it, or read the tag/casting number on the axle housing itself. If you've still got the axle's Meritor tag, that number is worth more than the truck's build year for figuring out what kit you need.
Ordering It From Us
We keep this one in stock in Tacoma for the guys running older C600s locally - if you're close enough to walk in, we'll have it ready same day. Ship it anywhere else in the country and it goes out the same day if you order before we close.
Comes with a 6+ month warranty, which is more than fair for a wear-item kit like this. If it's wrong for your axle, we'd rather swap it before you've got grease all over your hands than argue about it after.
Give us the number off the old kingpin or the axle tag if you've got it, or the full VIN if you don't - we'll confirm fitment before it ships, not after.
R201312 Cross-Reference & Interchange Numbers

Frequently asked questions
Does R201312 fit my Ford C600?
It fits C600s built with the Meritor 460.166C steer axle, which covers most of the 1980-1986 run, but Ford sourced axles from more than one supplier over those years. Check the tag on your axle housing or give us the VIN and we'll match it before you order.
Is this the same as the International 597258C91 kit?
Same kingpin kit design - International used this axle in some of their trucks too and 597258C91 is their catalog number for it. Mechanically it's the identical kit, just a different parts book stamp.
My old kingpins are worn oval - will this kit fix the knuckle without replacing the whole axle?
Usually yes, as long as the knuckle bore itself isn't hammered out beyond spec. Measure the bore before you order - if it's egg-shaped from years of a loose pin, you may need the knuckle machined or replaced along with the kit.
