This is a key wear-resistant component of the gearbox shift mechanism, compatible with mainstream heavy-duty truck gearboxes for HOWO, Steyr, Sitrak and other models.

Manufactured from high-quality alloy steel and strengthened by heat treatment, it features high hardness, excellent wear resistance and impact resistance. It resists deformation and cracking under long-term high-frequency shifting conditions.

With precise and standard dimensions, it is fully interchangeable with original parts and easy to install without modification. It can stably support the lock plate structure, evenly distribute stress, reduce component wear, and improve the stability and service life of the shift mechanism. It is a reliable replacement part for gearbox maintenance.
