WG222010049 Aluminum Transmission Rear Housing is an original OEM part for Sinotruk, compatible with HW series transmissions of Howo, Sitrak and other heavy-duty truck models.
It is integrally cast from high-strength aluminum alloy, reducing weight by about 40% compared with cast iron to realize lightweight design and lower fuel consumption.
It features high rigidity, excellent impact resistance and vibration resistance, perfectly adapting to complex working conditions.
Adopting precision CNC machining, the end face achieves high sealing accuracy to prevent oil leakage, dust and moisture intrusion.
With 1:1 original factory mounting hole positioning, it requires no modification and is plug-and-play. It balances excellent heat dissipation and
durability, effectively extending the service life of the transmission.
