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.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\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.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e\u003cspan\u003e The use of full width pinion gears is highly recommended.\u003c\/span\u003e\u003c\/p\u003e","brand":"Kimbrough","offers":[{"title":"Default Title","offer_id":52564647280929,"sku":"KIM147","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/5766\/9665\/files\/kim147.jpg?v=1776101321","url":"https:\/\/997rcraceway.com\/products\/kim147-kimbrough-48p-spur-gear-84t","provider":"997 RC Raceway","version":"1.0","type":"link"}
