Shovels forever! Convert your old rumblin’ mill into a purring interstate mile eater. These transmissions are replacements for the 1970-early ’84 Shovelhead 4-speed units. They bolt directly into your stock frame and your stock 4-speed primary and dry clutch bolt right up.
The BAKER 6 into 4 has a 1:1 fifth gear and a 0.86:1 overdrive sixth gear for a 500 rpm reduction in cruising rpm on the highway. There is no provision for mechanical speedo drive, but the case accepts a sensor.
gear ratios:1st - 2.94:1
2nd - 2.21:1
3rd - 1.60:1
4th - 1:1.23
5th - 1:16th - 1:0.86
Due to the extended length of the transmission on the kicker side, the exhaust pipe, oil tank and electric starter mounting brackets may have to be modified. Some inner primary covers require modification to clear the main drive nut.
