Toyota W59 Input Shaft
Description
Direct-replacement input shaft for the Toyota W59 5-speed manual used in RWD light-duty applications (e.g., Hilux/Tacoma and related models—verify by transmission tag). The helical drive gear is precision-hobbed for smooth, quiet mesh with the countergear, while journals, splines, and locating faces are CNC-machined and precision-ground for an OE-matched drop-in. Built from case-hardening alloy steel and carburized & quenched to withstand high mileage and towing use. Pair with the correct countergear and 1–2 synchronizer set during rebuild.
