The transmission is one of the most important, and most notorious, parts in any motorized vehicle. Harley owners know as much as anyone how vital a good transmission is getting power to the wheels – and how much of a pain it can be when it underperforms or fails. If you’re looking for more out of your motorcycle or want to start over, you can find a huge selection of quality Harley transmission parts here at Dennis Kirk. We have everything from primary covers to gaskets at low prices to increase power, acceleration and torque for the speed fiend inside.

Whatever ails your Harley transmission, we’ll help you get it running better than ever. We have Harley mainshafts, countershafts and kick-start shafts for 5-speed Shovelheads, 4-speed Sportsters, 4-speed Big Twins and more. These transmission shafts are machine-ground and heat-treated to shift faster and run longer than factory stock. For those want better acceleration or more top-end speed, Harley gear sets such as the Baker Drivetrain 6-Speed Gear Set will fit right in an existing 5-speed case to completely revamp your RPM band. We also have individual replacement Harley gears for rebuilds and repairs.

To add some style while protecting your transmission from gunk and grime, install any of our great-looking Harley transmission covers. We have machined inner primary covers, outer primary covers, top covers, side covers, chain inspection covers and derby covers in gleaming colors and designs. All the little parts and accessories you need are in stock as well, including spacers, kickstarter pedals, shifter levers and dipsticks. If you want to renew your transmission without replacing it, our transmission rebuild kits contain the gaskets, seals, bearings and locks.

There are a lot of different Harley transmissions out there, and as an authority on the classic American motorcycle, we have the parts and expertise to make yours run like a dream. Call us today or use our fitment tool to find the right parts for your needs without ordering the ones you don’t, and they’ll be on your front porch before you know it so you can head out to the garage.
