FITMENT • 1939–'89 FEATURES AND BENEFITS

• Contain all the components that need to be installed on the pinion shaft for the specified year group. • Kits for 1939–’53 and 1954–’77 can be used in 1972 and earlier engines to speed up the oil pump by 25% for more potential oil volume, since S&S oil pump drive gears are of the 1973 and later 6-tooth design.
