20CrMnTi steel differential gear + 7075 aluminum differential case, The center differential is fully assembled, Replaces factory part number (ARA-2985)
This center differential features a redesigned internal structure with thicker gears for tighter meshing, significantly reducing power loss and improving power output efficiency to more effectively transmit the torque generated by the motor.
This Center differential (38T / M0.8), paired with GPM motor plate and 15T motor pinion gear, is the optimal upgrade kit. This setup is compatible with 11T–23T motor pinion gears (0.8 module, Motor Shafts Bore: 3.175mm). If you need to install different teeth, GPM also offers 15T–30T motor pinion gears (0.8 module, Motor Shafts Bore: 3.175mm) sold separately for flexible choices.
Note: No differential oil, you need to add differential oil by yourself (For the front differential, we recommend using 50K CST silicone oil; for the rear differential, we recommend 30K CST; and for the center differential, we recommend 500K CST or 1000K CST)
Requirements: All packaging accessories are pre-assembled, and it is recommended to use medium-strength screw glue to ensure stability and prevent loosening.
