Baker 6in4 Overdrive Transmission Raw Finish

Years ago we 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-4’s 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
