There are three distinct year groups in eight different color-coded sizes for optimum gear lash available for big twin engines. The S&S color codes match Harley-Davidson color codes so replacement is easy. Just pick the appropriate color S&S gear that matches the color on your OEM or old stock gear. We have other the other gear pinions (by color) up for sale in our eBay Store.
S&S does not offer a replacement pinion shaft for 1990-99 big twin engines that accepts a stock pinion gear, oil pump drive gear, gear spacer and pinion gear nut, because experience has shown that the design is not strong enough for performance applications. For this reason, we recommend and sell only the pre-1990 style pinion shaft for big twins. To make the change easier, S&S offers a conversion package consisting of a pinion gear, spacer, nut and oil pump drive gear for big twin engines. All reference to H-D part numbers is for identification purposes only. We in no way are implying that any of S&S products are original equipment parts or that they are equivalent to the corresponding H-D part number shown.
