This drive shaft assembly is specially developed for BYD Fangchengbao Tank 7 new‑energy off‑road SUV, designed to transfer high motor torque for 4WD chassis, reliable for harsh off‑road conditions
The shaft bar is made of high‑strength alloy steel. Splines are manufactured by cold spline rolling process. Outer CV joints adopt intermediate frequency induction quenching treatment to improve surface hardness and anti‑fatigue performance. High static torsion strength resists instant high‑torque impact, reducing abnormal noise and fracture risk under bumpy off‑road driving.
Inner & outer CV joints are built with wear‑resistant steel. Heavy‑duty anti‑aging rubber boots prevent dust, sand and mud ingress for long service life. OE‑matching dimension enables direct bolt‑on replacement, no chassis modification required for easy installation.
