 This is a 84 tooth 48 Pitch Traxxas spur gear from Kimbrough Products. This spur gear is intended for use with 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.
NOTE: The use of full width pinion gears is highly recommended.
