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.

Baker Transmission dipstick

My Baker transmission dipstick was delivered quickly to the house. It is one solid piece and the chrome is beautiful. I expect it to last the life of my Harley. I would definitely use Baker again for my future needs. Thank you

Transmission Dip stick and DD6 gear set

Very happy with both purchases. Took a few miles to get use to the 6 over the 5 speed difference, but love it now.

Baker Drivetrain customer for life.

Awesome experience dealing with Baker Drivetrain. Parts shipped right away, and as soon as I got my hands on them I could tell they were high quality. Not to mention when I stopped at the Baker trailer at the Delmarva bikefest the year before last, the guys went out of their way to try and help me. Thanks To everyone that makes Baker Drivetrain a great company to work with.
