Our complete gear sets include all necessary sprockets to properly overhaul a 4-speed transmission for Harley-Davidson Sportster models. In addition to the standard ratios, we also offer “close ratio” sets that feature a longer input gear pairing for a sportier shifting experience.
The standard set has an input gear ratio of 18/26 (1:1.444), while the close-ratio set uses 17/27 (1:1.588) for tighter gear spacing. The 4th gear remains at the factory standard 1:1 ratio in both versions.
These gear sets are ideal for transmission rebuilds and performance upgrades on Harley-Davidson Sportsters, ensuring precise fitment and high durability.
Installing kit WW# 78-175 in Sportster transmissions 1986-up requires the use of an Andrews countershaft WW# 78-110, the stock countershaft does not fit. Also required are one or two thrust washers of the group WW# 77-550 to 77-553.
