The range gear shift fork shaft is integrally precision-forged from high-quality alloy structural steel. Through quenching and tempering treatment as well as precision grinding technology, it features high overall strength and rigidity, excellent resistance to bending and torsion, and is not prone to deformation and bending under long-term stress.

The shaft body boasts high surface finish and precise dimensional tolerances, sliding smoothly without jamming and maintaining an accurate fitting clearance with shift forks and bushings.

It delivers outstanding wear resistance, fatigue resistance, rust and corrosion resistance, perfectly adapting to harsh working conditions of heavy-duty trucks such as frequent gear shifting and heavy-duty bumpy driving.

With original factory standard specifications and great interchangeability, it achieves accurate assembly alignment. It effectively ensures sensitive and smooth high-low gear switching, reduces faults like stiff shifting, jamming and gear jumping, and maintains a long and stable service life.
