Description

Stock replacement parts for the 4 speed and 3-and-reverse transmission as used in 1936 thru 1986 Big Twin models. As always, we show OEM part numbers for reference only. The actual OEM part might have been slightly different or could have included a bushing, washer or retaining ring where the replacement is just the main part. Replacements however can be used for the years as indicated but please note that after all these years your transmission may no longer be completely like stock. All parts are sold each unless differently indicated.

Stock replacement mainshaft for Big Twin 1970-early 1985 fits OEM as well as aftermarket 4 Speed transmission.
