Fork Shaft Component – Complete AMT Shift Fork Shaft Kit for HOWO Max 4X2

The Fork shaft component is a complete set of precision shift fork shaft assemblies engineered specifically for the HOWO Max 4X2 AMT transmission, ensuring accurate and reliable gear selection across all forward and reverse gears. This comprehensive kit includes four critical assemblies: the Reverse-gear shift fork shaft assembly (12-gear, AMT, For helical tooth),

the First/second gear shift fork shaft assembly (AMT), the Third/fourth shift fork shaft assembly (AMT), and the Fifth/sixth gear shift fork shaft assembly (AMT, For helical tooth). As genuine howo Parts, the Fork shaft component meets the highest OEM standards,

delivering the durability and precision that professional drivers rely on for consistent, smooth gear changes. Every shaft in this Fork shaft component is manufactured to exacting tolerances, with hardened surfaces and precise detent grooves that ensure positive fork engagement and extend transmission life.

The Fork shaft component integrates the reverse gear fork shaft, the first/second, third/fourth, and fifth/sixth gear fork shafts, each tailored to the AMT’s helical tooth architecture. These shafts are the backbone of the shift rail system, translating actuator motion into precise fork movement for gear engagement.

Each Fork shaft component is precision-ground, heat-treated, and coated to resist wear and corrosion, ensuring long service life and consistent shift quality. This Fork shaft component is the ideal solution for rebuilding the AMT shift mechanism, restoring the crisp, positive engagement that drivers demand.

With the Fork shaft component, you can restore the shifting precision of your HOWO Max 4X2 AMT, eliminating play and ensuring reliable gear selection in all conditions. Trust in HOWO’s engineering and the quality of this Fork shaft component to keep your truck performing at its peak.

Reverse-Gear Shift Fork Shaft Assembly (12-Gear, AMT, For Helical Tooth)

The Reverse-gear shift fork shaft assembly is a precision component designed specifically for the 12-speed AMT transmission, engineered for helical tooth gear sets. This shaft controls the engagement of the reverse gear, ensuring smooth and reliable backward motion. Its hardened surfaces and precise detents provide positive fork positioning,

reducing the risk of gear clash. The shaft is manufactured from high-strength alloy steel with induction-hardened bearing journals, offering exceptional wear resistance and durability. This Fork shaft component is essential for maintaining the integrity of the reverse shift mechanism, preventing misalignment and ensuring that reverse engages cleanly every time.

First/Second Gear Shift Fork Shaft Assembly (AMT)

The First/second gear shift fork shaft assembly is the primary actuating rod for the lower gears, responsible for engaging first and second gears in the AMT transmission. This shaft features precise grooves and detent profiles that interact with the shift forks to ensure accurate gear placement.

Its robust construction and surface hardening provide resistance to wear and deformation, ensuring consistent shift feel over the long term. This Fork shaft component is critical for smooth starts and low-speed maneuvering, and its replacement with a genuine part restores the precision of the shift mechanism, eliminating play and improving driver confidence.

Third/Fourth Shift Fork Shaft Assembly (AMT)

The Third/fourth shift fork shaft assembly handles the mid-range gears, providing smooth transitions between third and fourth speeds. This shaft is engineered with precision-ground surfaces and accurate detent slots to ensure positive fork engagement, minimizing shift effort and preventing gear clash. Its high-strength steel construction and heat treatment ensure durability under the moderate loads of highway driving. This Fork shaft component is essential for maintaining the shift quality in the most frequently used gears, and its replacement with a genuine part ensures consistent performance and extended synchronizer life.

Fifth/Sixth Gear Shift Fork Shaft Assembly (AMT, For Helical Tooth)

The Fifth/sixth gear shift fork shaft assembly is designed for the high-speed gears, enabling smooth upshifts and downshifts between fifth and sixth gears. This shaft is optimized for the helical tooth gear set, reducing noise and vibration while ensuring precise fork movement. Its advanced surface treatment and precise machining provide exceptional wear resistance, even under high-speed, high-load conditions. This Fork shaft component is vital for highway cruising and overtaking, and its replacement with a genuine part restores the shift precision and reliability of the upper gears, enhancing overall driving comfort and fuel efficiency.
