About This Product
This Andrews 27-tooth first-gear transmission mainshaft replaces Harley-Davidson OEM part 35277-52A and fits 1952–1956 K and KH models as well as 1957–1990 four-speed XL Sportster transmissions. Manufactured in the USA from high-alloy nickel steel, it is ground to precise dimensions, heat-treated, and shot-peened for strength and durability. Andrews has maintained race-quality standards for decades, making this a reliable replacement when your original first-gear mainshaft is worn or damaged. A direct-fit component that restores factory-correct operation to your Sportster's gearbox.
Manufacturer part number: 251050.
