Transmission Dipstick

Have you ever heard of a 5-speed transmission dipstick breaking off and working its way into the gearbox with disastrous results? Ask any seasoned technician; he’s seen one. The low frequency firing pulses of the American V-Twin make the stock zinc die-cast dipstick go into resonance like a suspension bridge in a severe windstorm. Over time, the stalk breaks off and you know the rest of the story. Bigger engines make this situation even worse. We redesigned the dipstick with the largest radius possible between the stalk and the head. This radius stiffens the dipstick and increases its natural frequency. Our dipstick is made of billet aluminum and is show-polished with an o-ring.
