These Rear CVD Drive Shafts are engineered as a direct-strength replacement for the ARRMA MOJAVE GROM MEGA stock components. Machined from 4140 medium carbon steel, the parts offer improved tensile strength and wear resistance for repeated high-load cycles. The heavy duty CNC machined steel wheel stub axles replace the original CVD dog bone and plastic wheel shafts, delivering a measurable increase in drivetrain robustness while maintaining alignment and fitment.
