What's in the Box and What It Fits
This kit covers the kingpin, bushings, thrust bearing, seals, and the lock/set hardware for one side of the front steering axle on an International 1724 built '79 through '85. Some kits are sold per side, some are full-axle sets - check what you're ordering against what the old part number said, because IH ran a few different axle setups across that model run depending on GVW rating and whether it was a straight truck or tractor.
The kingpin itself is the pivot pin the steering knuckle swings on. When it wears, or the bushings wear around it, you get wandering steering, uneven tire wear on the front, and a truck that darts under braking. If your steering wheel's got more play than it used to, or the mechanic's telling you the knuckle rocks on the axle when you jack it up, this is the fix - not an alignment, not new tires.
Reading the Cross-Reference Numbers
R200042 is the number stamped or cataloged as the base part. TDAR200042 and S524241601 show up because different IH parts distributors and axle suppliers relabeled the same physical kit under their own systems back in the day - that happens a lot with kingpin kits since Rockwell, Eaton, and IH axles shared a lot of common hardware. M-2332 is another supplier's house number for the identical kit.
Where kingpin kits go sideways is bushing inside diameter and kingpin length - even a few thousandths off, or a pin that's a half-inch short, won't seat right in the knuckle bore and you'll be fighting it all day. The cross-listed numbers here (KPK1134, 300-205, E4693B) are commonly cataloged as matching this same kit, but they came from different manufacturers, so specs can drift over the years even when the number lines up.
Bottom line - pull the old kingpin or the number off the axle tag and match it against what's listed here before you order. If the old parts are worn past reading any numbers, get the axle model or VIN and we'll cross it from our end.
Ordering From PartStop
We're in Tacoma and if you're local, this kit's usually on the shelf for same-day pickup - useful when a truck's down and sitting on jack stands is costing somebody money. If you're not local, we ship nationwide, and freight on suspension parts like this is usually quick since it's not oversized.
Every kit we sell carries a 6+ month warranty. If it doesn't fit once you get it in hand, or something's off with the bushing sizing, call us before you press anything in - it's a lot easier to sort out returns before the press tool's been near the part.
R200042 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to R200042. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does R200042 fit my 1724, or do I need to check something first?
It's cataloged for the '79-'85 International 1724 front axle, but IH ran a few axle variations in that span depending on GVW and axle manufacturer. Surest way to confirm is pull the old kingpin kit part number off the knuckle or check your axle tag, and match it against this listing before ordering.
Is this the same kit as KPK1134?
KPK1134 is commonly cross-referenced to this same kingpin kit in parts catalogs, and it's typically the same physical parts under a different supplier's numbering. That said, confirm bushing ID and kingpin length against your old kit - or give us the axle info and we'll double check before you order.
What's actually included, and do I need anything else to do the job?
This kit is the kingpin, bushings, thrust bearing, and seals for one side of the axle. You'll want new cotter pins, and depending on axle condition you may need a kingpin press or access to one - this isn't a job most guys do with hand tools alone. Check with your mechanic before you order if you're not sure what press equipment they've got.
