Andrews gears for 4-speed Sportster gearbox - Clutch gear XL71-78 4-speed

These sprockets fit all 4-speed Sportsters from 1956 to 1990. The sprockets are made from high-nickel steel, heat treated and shot peened for maximum durability. With shot peening properly applied, wear resistance is significantly increased, especially in the corners of the teeth and their corresponding recesses.
