Associated 6693 Spur Gear 81T 48P RC10B3 RC10L3O RC10L3T RC10L4O RC10T3 RC12L3O

This is the genuine Associated 6693 spur gear, cut with 81 teeth at 48 pitch and built to fit a wide range of vintage Associated platforms including the RC10B3, RC10L3O, RC10L3T, RC10L4O, RC10T3, and RC12L3O. The spur gear meshes directly with your pinion gear to transfer power from the motor into the transmission, so its tooth count plays a direct role in your car's overall gearing and top speed.

Spur gears wear down over time from constant mesh with the pinion, especially on higher-power setups, and a worn or chipped gear can cause inconsistent power delivery or premature pinion wear. This 81-tooth, 48-pitch gear is a direct-fit factory replacement that restores clean, reliable meshing without altering your car's stock gear ratio.

Keeping a spare spur gear like this on hand is a smart move for anyone running one of these classic Associated platforms, since gearing parts in this exact tooth count and pitch can be hard to track down.
