This is a used 7DCT220 Automatic Transmission Differential Assembly, a core heavy-duty power transmission component specifically designed for BESTUNE T77 (2020-) models equipped with 7DCT220 7-speed dual-clutch transmissions.
As the "final drive" of the transmission system, the differential assembly is responsible for transmitting power from the gearbox to the drive wheels, enabling smooth cornering by allowing wheels to rotate at different speeds while maintaining consistent torque output. It effectively resolves common issues such as differential noise, gear wear, vibration, power loss, and abnormal operation, fully restoring the vehicle's drivability, acceleration performance, and transmission reliability.
All our used differential assemblies undergo 100% strict professional testing (including gear tooth wear inspection, backlash measurement, runout testing, load bearing endurance testing, and noise vibration testing) before shipment, guaranteeing perfect fitment, reliable power transmission, and full compliance with OEM standards. This assembly is an ideal cost-effective replacement for damaged, worn, or faulty original differential components, perfect for transmission repair and overhaul.
2. Compatible Vehicles
