The Exotek B64 Heavy Duty Spur Gear is machined from heavy duty pom (delrin) material with a thicker mounting base but same teeth width and size as the stock 81t spur which eliminates the problem of the soft stock gears flexing and stripping out under high load race conditions. Includes mounting hardware and instruction sheet- but bolts right on to the stock gear diff. Not for the slipper set.

I went through one Associated spur gear a month before trying these, this spur gear lasted five months of racing. Will definitely buy again.

Using this on a Yokomo Yz4sf2 gear diff, it fits perfectly.
so far so good. one race day and no significant signs of wear.
one thing to note is that it is a wee bit thicker than the stock spur, it actually is the exact same width as the robinson hardened steel spurs, they match perfectly.
