Description
The Andrews 5-Speed Big Twin Transmission Gear Sets offer robust and durable performance for motorcycle enthusiasts. Constructed from high nickel alloy, these gears are heat-treated and shot-peened to enhance their strength and longevity. The gear sets include stock replacement options for first through fifth gears, as well as a close ratio 2.94 first gear set. This close ratio option provides smoother shifting from first to second gear and allows for an increase in speed by 5 mph at peak RPM compared to a 3.24 ratio. Additionally, many of the gears feature machined lead-in ramps to improve shifting and minimize wear on drive components.
