This ZF 1358 304 010 mainshaft reverse gear is specifically designed for ZF 12-speed AMT transmissions. Forged from high-strength alloy and treated with precision carburizing and quenching, it features high tooth surface hardness, excellent wear resistance and impact resistance, standing up to repeated reverse gear shocks under heavy-duty conditions. Factory-grade precision tooth profile machining ensures uniform meshing clearance, delivering smooth reverse shifts without gear rattling noise and significantly improving transmission stability. Ideal for heavy-duty commercial vehicle applications, it is a core component for the stable operation of the transmission’s reverse gear system. Its original quality ensures a perfect fit with the mainshaft, enabling hassle-free one-step replacement during maintenance.

1358 304 010 Main Shaft Reverse Gear
Part No. 1358 304 010 is the mainshaft reverse gear, compatible with ZF 12AS series 12-speed AMT transmissions. Installed on the transmission mainshaft, it is a critical component for power transmission in reverse gear.
The gear is integrally forged from high-alloy steel, with its tooth surfaces precision ground to tolerances strictly adhering to OEM standards, ensuring accurate meshing with the mainshaft and idler gear.
Suitable for commercial vehicles such as heavy-duty trucks and buses, it withstands high torque shocks during reverse operation, resisting tooth breakage and wear even after prolonged use. Replacing this part restores the transmission’s reverse gear function, eliminates abnormal noise and jamming in reverse, and ensures driving safety.
