Avetlink AK Rear Axle Differential for Heavy-Duty Vehicles
Heavy loads and rough roads can cause differentials to jam, make unusual noises, or suffer gear damage. Frequent repairs interrupt transport and increase operating costs.
The Avetlink AK rear axle differential gearbox offers 16T and 18T gear configurations for demanding cargo and construction vehicle applications.
High-strength alloy materials and precision heat treatment help the gears withstand sudden torque loads. The differential allows the rear wheels to turn at different speeds when needed, supporting smooth cornering and reliable power transmission.
When matched with a suitable motor and controller, the drivetrain can deliver smoother power and reduce stress on its components.
Reported application results show that the interval between failures increased by more than three times, helping reduce maintenance frequency and costs.

Key Features
- Strong impact resistance: Designed to withstand torque shocks during heavy-load operation.
- 16T and 18T options: Select the configuration that matches your rear axle and drivetrain requirements.
- Effective sealing: Helps protect internal components from dust and moisture.
Maintenance Tips
- Check the gearbox oil level regularly and keep the lubricant clean.
- Use the oil grade and viscosity specified for your AK configuration.
- Avoid mixing gear oils from different brands or formulations unless their compatibility has been confirmed.
- If the differential housing temperature exceeds 120°C, stop operation and allow it to cool. Follow any lower temperature limit specified for your configuration.
