The 1328 333 009 auxiliary box cone hub is suitable for ZF 12-speed AMT heavy-duty truck transmission. It is integrally forged from high-strength alloy steel with high material density and strong load-bearing capacity. Supported by CNC finishing and heat treatment quenching and tempering, it balances hardness and toughness with excellent impact resistance, crack resistance and deformation resistance. Its cone and gear teeth feature high machining accuracy with perfect assembly fit and interchangeability, ensuring smooth meshing and eliminating shift abnormal noise and stuttering. It adapts to severe working conditions such as long-distance heavy load and climbing, wear-resistant and durable, being a high-quality original compatible part.

The 1328 333 009 auxiliary box cone hub is a core transmission component of the transmission auxiliary box, produced strictly in line with original size and process standards for direct replacement and installation without modification. Made of high-quality alloy base material with multi-layer precision processing and hardening treatment, it features stable internal structure and resistance to frequent shift impact. With uniform and regular cone lines, it delivers good transmission synchronization, reduces transmission load and slows down wear of matching parts. With precise workmanship and strict tolerance control, it fits mainstream heavy-duty trucks such as Sinotruk Howo, offering stable performance and lowering later maintenance cost.
