Major advantages of upgrading to this part/product：

Upgraded to 20CrInTiH steel material, Spiral cut ring gear, Main Diff Gear 39T Spiral, Main Input Gear 12T Spiral, 1.5Mod


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.


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. 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. After hardening treatment, the gear surface can better resist the wear caused by these forces and extend the service life of the gear.

Requirements: All packaging accessories are pre-assembled. It is recommended to use screw glue to ensure stability and prevent loosening.
