Differential rings and pinions are essential components of a vehicle's differential system. The ring gear is a large gear that is attached to the differential case and is responsible for transferring power from the driveshaft to the axles. The pinion gear is a smaller gear that is attached to the driveshaft and meshes with the ring gear to transfer power to the axles. These gears work together to allow the wheels to turn at different speeds, enabling the vehicle to make turns smoothly. Differential rings and pinions come in various ratios and materials, allowing for customization to fit specific driving needs.
