Precision-machined synchronizer tooth sleeve for XCMG LW300 & ZL30 series 3-ton loader transmissions. Made from high-strength alloy steel with heat-treated teeth for smooth gear engagement and long shift life. 100% OEM fit, ideal for transmission overhaul and clutch pack replacement.
High-Strength Alloy Steel: Made from premium carburized alloy steel with hardened engagement teeth (HRC 58-62) for superior wear and galling resistance.
Precision Tooth Profile: CNC-broached teeth ensure perfect meshing with synchronizer rings—eliminating shift clash and reducing wear on mating parts.
Tough Core, Hard Surface: Surface induction-hardened for durability, while the core remains ductile to absorb shock loads without cracking.
