This plastic is almost three times tougher and will withstand operating temperatures 75° to 125° higher than plastics used by other R\/C car gear manufacturers.\u003cbr\u003e\u003cbr\u003eKimbrough spur gears are full width, because a narrow or profiled plastic gear can deform under load, is weaker and less efficient. This can cause drag in the gear train and waste horsepower. The wider a gear is, the more load it can handle. The only time gear engineers narrow gears, is when there is a space limitation. Kimbrough Racing Products gears run quiet because they have the correct tooth shape and don't have to be narrowed. Choose from a variety of tooth count choices to allow you to fine tune the torque and top speed of your model.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe use of full width pinion gears is highly recommended.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"3.
