WG2203210188 is a dedicated gear shift booster for Sinotruk transmissions, compatible with a wide range of mainstream HOWO and SITRAK models.
It adopts a high-strength housing material as a whole, precision forged to withstand pressure and vibration, and is not easy to deform or damage.
The internal precision valve core and air circuit components are perfectly matched with sensitive air pressure response, powerful shifting assistance, light and labor-saving operation, effectively reducing the driving burden.
Equipped with oil-resistant and aging-resistant seals, it maintains tight sealing without air leakage or oil seepage, adapting to long-distance heavy-load transportation and complex road conditions.
With original factory standard dimensions, it can directly replace original parts with simple installation, delivering stable and durable performance.
