Import 2-Speed Transmission — Buy in wholesale FOB from Supplier in China

This Rawsuns 2-Speed Transmission, model R2S35B, is designed for electric car conversion kits, specifically targeting 4.5 to 6 ton trucks. The unit features a speed ratio of 2.704/1, with a maximum input torque of 350Nm and a maximum input speed of 6000rpm. It has a total weight of 30kg and external dimensions of 494mm by 343mm by 487mm. The transmission requires 0.7 litres of 75W-90 GL-4 grade lubricating oil.

The R2S35B model uses a gearshift mechanism designated as R500. For electric vehicle conversions in this weight class, a two-speed transmission is a standard solution to balance low-speed torque for hauling and higher efficiency at cruising speeds. The specified 75W-90 GL-4 oil is a common automotive gear oil, indicating the unit uses standard spur or helical gears rather than specialised EV reduction gearboxes. Its physical footprint is typical for a transmission handling this torque range in commercial vehicle applications.

This product is primarily sourced by workshops and integrators specialising in retrofitting diesel trucks to electric powertrains. The specifications suggest it is a standalone transmission unit, meaning buyers will need to source compatible electric motors, controllers, and mounting hardware separately. Prospective importers should confirm the exact output shaft dimensions and mounting bolt patterns with Rawsuns to ensure compatibility with their chosen motor and vehicle chassis. The stated maximum output speed of 6000rpm aligns with common permanent magnet synchronous motors used in this segment.
