BAKER Harley Complete 6-into-4 Transmission
Made to satisfy the old school tendencies while providing the ability to run reasonable RPM’s at highway speeds. Panhead and Shovelhead riders will love the ability to ride hard with their friends on late model bikes.
Case: The 6-Into-4 Transmission case comes in two different versions. Our 1936-64 case has no ear, to work with the factory primary. Our 1965-1986 version includes the primary ear bosses. These can be used with stock primary applications, belt drive applications, or running no primary plate at all. For the 1936-1964 Tapered Mainshaft applications, please note that the 6-into-4 case does not contain an alignment track or a provision for the primary adjustment bolt that you would normally find on a stock case.
4 different mainshafts available for Knucklehead, Panhead or Shovelhead:
1936 to 1964 Tapered Mainshaft**
1965 to 1969 Tapered Mainshaft
1970 to E1984 Tapered Mainshaft
1970 to E1984 Splined Mainshaft
1st Gear Ratio: The 2.94 1st gear ratio fits 1936-1986 FL & FX models. This gear ratio is an all around good ratio. The optional 3.24 1st gear ratio fits 1936-1986 FL & FX models and is recommended for heavy GVW applications. The R-Ratio 2.82 1st gear is for 1936-1986 FL & FX models and is recommended for light hot rods.
2nd Gear Ratio: We recommend a 2.21 2nd gear ratio for the 2.94 and 3.24 1st gear ratios. The 2.08 2nd gear is normally paired with the 2.82 1st gear for racing applications. If you would like a personalized 2nd gear pairing, please contact us through the website chat, email us at firstname.lastname@example.org, or call us Monday-Friday 8AM-7PM EST/EDT at 517-339-3835.
