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.

Kimbrough 48P Spur Gear (75T)
Bought this as an affordable and available replacement for my HPI RS4 sport 3 (since HPI now sucks and you can find parts except for ebay). This part is a great replacement to HPI part no. 113705. the only gotcha is that this Kimbrough spur gear only has holes for two of the 4 screws that the 'stock' spur gear uses to connect to the drive shaft rod housing. after screwing in two of the 'stock' screws (to align the drive shaft housing) a simple drill of the other holes allows the other two screws to be connected just fine. I could probably get away with just two screws, but I decided to drill so I could put all four just to be safe. That's a long winded response to say, this is a great product/item. Thumbs up.
