The R2S50B conversion gearbox is a dual-ratio transmission assembly designed for retrofitting internal combustion engine vehicles to electric or hybrid drive systems, particularly for light commercial trucks. It features an aluminum alloy housing with hardened steel gears and is rated for a maximum input torque of 500 Nm and input speed of 5000 rpm. The unit weighs 32 kg and measures 475x305x431 mm, allowing integration into existing chassis layouts without major structural modification.
The gear ratio of 1.00/0.76 enables direct drive for highway cruising and a lower ratio for hill climbing or heavy load acceleration. Lubrication is provided by 75W-90 GL-4 gear oil, with a capacity of 1.5 liters. The gearbox is designed for use with AC traction motors and is compatible with DONGFENG truck platforms, making it suitable for fleet electrification projects in Asia, Africa, and Latin America.
This unit is primarily purchased by EV upfitters, fleet operators converting diesel trucks, and regional parts distributors. Units are shipped in wooden crates with foam padding and protective caps on input/output shafts. Trade terms are typically FOB Shantou, with lead times of 4 to 6 weeks. Buyers should confirm gear tooth profile, backlash tolerance, and output flange type before ordering to ensure compatibility with existing driveline components.

Before ordering, verify the gear ratio, output flange dimensions, and input shaft spline count against your motor and axle. Request a dimensional drawing and gear tooth profile specification. Confirm the gearbox has been tested for vibration and noise levels under load. Do not assume compatibility with DONGFENG trucks without matching the exact model variant and driveline configuration.
Lead time is typically 4 to 6 weeks after deposit. Shipping is FOB Shantou Port, with CIF available. Payment terms are usually 30% advance, 70% against shipping documents. Buyers must confirm the gearbox is packed in a wooden crate with internal foam and desiccant bags to prevent corrosion during ocean transit. Request a packing list with serial numbers for each unit.
Upon delivery, inspect for physical damage and verify the model number matches the order. Check oil level and ensure no leaks are present. Test the gearshift mechanism for smooth engagement. Retain a sample unit for quality reference. Request a certificate of conformity and a test report showing torque transmission efficiency and thermal performance under simulated load.
