Toyota 1–2 Synchronizer Hub

Description

This part is the 1st–2nd gear synchronizer hub. Working with the 1–2 sleeve, shift fork and baulk rings, it transmits torque and locks the gear during engagement. Made from carburized alloy steel for a hard, wear-resistant dog profile with a tough core, it withstands heavy-duty commercial use. Ground bore and faces ensure OE-level concentricity for smooth shifts and reduced gear clash. Direct replacement for OE 33361-36030.
