Major advantages of upgrading to this part/product：

Spiral cut ring gear: The tooth design of the spiral cut ring gear allows the differential to distribute torque more accurately and efficiently according to the actual driving conditions of the wheels. For example, when the vehicle turns, the torque can be reasonably distributed to the left and right wheels based on the difference in rotational speed between the inner and outer wheels, allowing the outer wheels to obtain more power to travel longer distances, while the inner wheels will reduce power accordingly to ensure that the vehicle turns smoothly.

Meshing of spiral gear: During the meshing process, the contact between the teeth of the spiral cut gear is smoother. Compared with other tooth shapes such as straight cut gear, it can effectively reduce the noise and vibration generated during gear meshing. This not only improves driving comfort, but also reduces problems such as loosening and wear of components that may be caused by vibration, and extends the service life of the differential and the entire transmission system.

Enhanced transmission efficiency: The tooth surface contact area of ​​the spiral cut ring gear is relatively large, and the force is transmitted more evenly during the transmission process, which can effectively reduce the energy loss during power transmission process, improve the transmission efficiency of the differential, and enable the vehicle's dynamic performance to be better exerted, and perform better during acceleration, climbing, etc.

Hardening and blackening treatment: Hardening treatment can improve the surface hardness and wear resistance of the differential gear. During vehicle driving, the differential gear needs to frequently withstand various forces such as power from the drive shaft and the resistance of the wheel feedback. After hardening treatment, the gear surface can better resist the wear caused by these forces and extend the service life of the gear.

Upgraded to medium carbon steel material, Spiral cut ring gear, large bevel gear 30T, front and rear small bevel gear 12T
Requirements: All packaging accessories are pre-assembled. It is recommended to use screw glue to ensure stability and prevent loosening.
