This product is a differential pinion gear designed as a replacement drivetrain component for compatible Losi RC vehicles. It works within the differential assembly to transfer power from the driveshaft into the ring gear, enabling smooth and efficient torque distribution to the wheels. The precision-machined gear teeth ensure accurate meshing for consistent performance under high-load and high-RPM conditions. Built from durable materials, it is engineered to withstand the stresses of both racing and off-road driving. Ideal for replacing worn or damaged gears and restoring proper differential operation.
