WG2203220131 3rd/4th gear shift fork shaft assembly is forged from high-strength alloy steel with dense texture and outstanding toughness. It features excellent compression and bending resistance and is not easy to deform or bend.
Adopting precision heat treatment of quenching and tempering combined with high-frequency quenching, it has high surface hardness, good wear resistance and impact resistance, and can withstand the load of long-term frequent gear shifting.
The shaft is processed by precision turning and grinding with accurate coaxiality, sliding smoothly without jamming. It ensures stable and sensitive shifting between 3rd and 4th gears, effectively preventing gear jumping, gear slipping and shifting abnormal noise.
Made in original factory standard specifications, it has high interchangeability and requires no modification during installation. It is suitable for maintenance and replacement of heavy-duty truck gearboxes, durable and worry-free.
