What You're Actually Buying
This is a full kingpin kit for the MFS series front steer axle — pins, bushings, thrust bearings, seals and the hardware to put it back together. Double pin design means you're servicing both the upper and lower on that steer knuckle, not just one.
MFS13, MFS14 and MFS66/66+ all share this same 1.794" pin diameter and 9.016" length, which is why one kit covers all three axle families. Meritor built a lot of trucks off this basic axle architecture, so it shows up on more trucks than guys expect.
Before you order, pull the number off the old kingpin or check your axle tag. MFS axles get rebuilt more than once in their life and somebody may have already put a different diameter or length pin in there on a prior repair.
Why All Those Numbers Cross
R201608 is the number this kit lives under in most catalogs, but Meritor's own part numbers — 460.608CP, 460.608E, 460.608X — are the same physical kit under Meritor's numbering scheme. RC-R201608 and ATM-460.608C are remanufacturer/aftermarket house numbers for the identical spec kit.
TDAR201608, S537081062 and SKS13118 are cross-reference numbers other suppliers use for this same kit — different labels, same pin diameter and length. The dimension is what matters here, not whose sticker is on the box.
Where guys get burned is thrust washer thickness and seal fit — some axle rebuilds down the road have swapped in oversize bushings or a different seal package. If your knuckle's been sleeved or bored oversize before, this kit may not drop in clean. Check the number stamped on the old kingpin or your axle's build tag against what we've got listed.

Frequently asked questions
Does R201608 fit my Freightliner with an MFS axle?
Depends which MFS axle is under it — MFS13, MFS14 and MFS66+ all use this 1.794" x 9.016" pin, but Freightliner's put other axle families under their trucks too. Check the axle tag or give us the VIN and we'll confirm before you order.
Is this the same as Meritor 460.608CP?
Yes — 460.608CP is Meritor's own number for this identical kingpin kit, same diameter and length spec as R201608. Different part number, same physical kit.
What's actually in the kit — just the pins?
No, it's the full kingpin service kit — pins, bushings, thrust bearings and seals, plus the hardware needed to rebuild the knuckle. You'll still want your shop manual handy for torque specs and preload on reassembly.
