Years ago Baker Drivetrain came out with the 6-into-4 for Shovelheads. Sales of these transmissions have been a complete shocker and the message is loud and clear: People love their Shovelheads and they ride the piss out of them. We often get asked “why not a 5-into-4?”. This is because 4-speeds have a 1:1 fourth gear and Evo 5-speeds do as well. This provides no RPM advantage to your old iron. 6-into-4s have a 1:1 fifth gear and a .86:1 sixth gear; good for a 500 RPM reduction on the highway. Our original 6-into-4 transmission is a direct replacement for the 1970-Early 1984 4-speed. This year we have main shaft options that allow fitment into wet (diaphragm) clutch model Shovels and 4-speed Evo models that require a longer main shaft and shorter ones for Pan and Knuckle. Available with different kicker covers.
