The best drivers in the world trust Kimbrough gears, so you know you can too!\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eKimbrough spur gears are molded with black 4\/6 Nylon plastic, because black dissipates heat into the air better then any other color - and high temperatures are not good for thermo-setting plastics. 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 options 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","brand":"A MAIN","offers":[{"title":"Default Title","offer_id":51347524256022,"sku":"KIM199","price":6.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/9974\/5341\/files\/Screenshot2026-05-28143131.jpg?v=1780003979","url":"https:\/\/www.mikeshobby.net\/products\/kim199-kimbrough-64p-precision-spur-gear-76t","provider":"Mike's Hobby","version":"1.0","type":"link"}
