Fabco TC-38 Transfer Case Parts List — Every Part Number, In Stock Online
This is the complete factory service parts list for the Fabco TC-38 transfer case, organized by shaft assembly exactly like the factory book — rear output, front output, intermediate and input shafts, plus the air-shift assemblies and case parts. Every Fabco part number below links to that exact part at Pro Gear & Transmission, Fabco’s authorized distributor. Check the nameplate on your transfer case before ordering, or call 877-776-4600 and we’ll identify what you need from the serial number. Parts marked NLA are no longer available new — superseded numbers link straight to the current replacement part.
