{"product_id":"87-tooth-spur-gear-48-pitch","title":"87 Tooth Spur Gear 48 Pitch","description":"Kimbrough 48P Spur Gear (87T)    Kimbrough Products 48 Pitch 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.    Kimbrough 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.    NOTE: The use of full width pinion gears is highly recommended.","brand":"Eds Hobby Shop","offers":[{"title":"Default Title","offer_id":52134514688281,"sku":"KIM148","price":6.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0776\/7467\/6505\/files\/kim148.jpg?v=1773763953","url":"https:\/\/edshobby.com\/products\/87-tooth-spur-gear-48-pitch","provider":"Eds Hobby Shop","version":"1.0","type":"link"}
