210150 4-speed transmission gear kit

This Andrews 4-speed transmission gear kit is designed for 1936 to early 1976 Big Twins and features a 2.44 first gear and a 1.35 third gear ratio. This specific combination is often preferred for heavier bikes, like the Electra Glide, as the 2.60/1.35 setup provides a better pull away from traffic lights. The kit is sold as a kit and includes six gears, two shifter clutches, and two forks, all manufactured from high-quality nickel alloy steel that has been heat-treated and shot-peened for maximum strength. Upgrading to Andrews gears is a proven way to improve shifting reliability and overall transmission life on vintage Harley-Davidson motorcycles, though additional small parts may be required for a full rebuild.
