KIM163 48P 76T Differential Spur Gear
Differential Spur Gear 48P 76T for 1/12 and 1/10 scale cars. Made of super strong nylon with 12 ball bearing holes on outer hole circle.
These gears are available in a variety of tooth count options to fine tune the torque and top speed of your vehicle. Larger the pinion more torque and smaller for higher top speed.
Kimbrough 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.
