The Precision Spur Gear TD 48dp 78T is specially designed for the use with Team Durango's line of 1/10th scale vehicles. The gears are precision machined from our specially formulated composite material to ensure highest strength, lowest running noise and best reliability. The precision machining not only increases the durability of the gears but also helps when setting gear mesh. All gears feature machined venting holes to reduce heat build-up when running a soft slipper setting and they come with engraved size markings for easy identification. RDRP's spur gears are available in sizes of 78T, 83T and 87T, ideal for all modified racing classes.
