Left Final Drive Half-Shaft

The Left Final Drive Half-Shaft is a critical component of your vehicle's final drive system. It transfers power from the differential to the left drive wheel. Yancheng Botu Transmission Machinery manufactures this shaft from forged 42CrMo steel, followed by quenching and tempering. The journal is high-frequency hardened, and the spline and bearing seat are precision-ground. This ensures high torque capacity, long-term reliability, and smooth power delivery. A strong Left Final Drive Half-Shaft keeps your vehicle moving confidently.

42CrMo steel and our tempering process provide a tensile strength of 950MPa or more, sufficient for full drive torque. The spline teeth are high-frequency hardened to HRC50–55 for excellent wear resistance. Large step radii eliminate stress points, increasing fatigue life. This half-shaft is designed to withstand tough road and field conditions, maintaining performance even under heavy loads.

With 8 years of experience in transmission parts, we understand the demands on half-shafts. We optimize material selection and heat treatment for heavy-duty use. Full CNC equipment, including CNC lathes, spline mills, and cylindrical grinders, ensures consistent accuracy. Machines are regularly calibrated. Each Left Final Drive Half-Shaft undergoes thorough inspection and comes with a 1-year warranty. Fast after-sales support is provided, with free replacement or repair for quality issues.
