When you're buying a BAKER Drivetrain transmission getting the best shouldn't be good enough. You may deserve better than that when there are standards to meet and goals to reach. This is why its part of our winning plan to make sure you're advised before, during, and after your purchase.We make sure you're covered with a tremendous 5-Year Limited Warranty on your Softail transmission after you buy it.
We believe in choices to tune your transmission to your standards. Pulley or sprocket? Would our 'R' Ratio 1st and 2nd gears be the ratio of choice for you? Would an ignition-kill shift kit shave your time on the track?
We believe in sacrificing in the name of holding our commitment to premium quality. Our releases take longer to get to market. Our products may cost more. Our warranty is one the industries longest. We'll ask the hard questions if you're not perfectly satisfied. It's all painful stuff, but we can take it. This is because we know its worth it. Nobody goes where we go...and it pays off.
We believe in American made products, especially for the American motorcycling culture. It's our duty as industry leaders to keep the quality of our products high, as well as keeping the quality of our company just as high. This all may go away if industry leaders don't set the quality standards and support the scene.
We work hard to ensure our customers believe in us. Whether you're riding across the country on a epic journey, or you're breaking a speed record somewhere, or you're trusting that the judges will see our brand name on your bike and consider it for points. Hell, believe in us even if you ride like an asshole bastard as you split lanes, rip on your bike, give it hell, and beat the shit out of it between bars. That's the idea! Have fun and worry not about your tranny!

APPROACHABLE FUNCTION-FORMED LOOK
WITHOUT HAVING TO PAY FOR OVERKILL STRENGTH
The design directives for the TorqueBox were clearly established in the early stages of development. This flagship gearbox had to have a 250 ft-lb torque capacity gearset but externally look like 400 ft-lb standing still. Development costs and resultant retail price were deemed irrelevant. By choosing the venerable 6-71 blower for architectural inspiration, we inadvertently gave rise to what is now trademarked as
Function Formed™ design.
Enter the new PowerBox; Function Formed™ looks without the need to pawn your guns or your wife’s jewelry.
Design inspiration from the TorqueBox coupled with a diamond ground 8620 steel 6-speed overdrive gearset
gives the PowerBox an input torque capacity of 165 ft-lb, with a 400 ft-lb curb appeal; some may argue more.
More because the tidy compact design of the PowerBox makes the function Formed design elements pop out
more. 34Ds will always be noticed more on a petite chick than a larger chick; same concept.
Hydraulic clutch actuator only.
No neutral switch hole in the top cover
Speedometer hole for LSD or RSD
