Kimbrough 387 48P Traxxas Spur Gear (87T)

Kimbrough Products 48 Pitch Traxxas spur gears were developed for Traxxas 1/10 Electric vehicles. Kimbrough Racing Products Plastic Gears have been used to set all of the unlimited speed records for R/C 1/10 scale electric cars in the U.S., and are used by a majority of the top professional R/C car racers around the world. The best drivers in the world trust Kimbrough gears, so you know you can too!

Kimbrough 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.
