210450 4-speed transmission gear kit

This Andrews 4-speed transmission gear kit is a high-quality replacement for 1936 to early 1976 Big Twins, featuring a 2.60 first gear and a 1.23 third gear ratio. This combination offers a great balance, giving you a strong pull off the line with the 2.60 first gear while the 1.23 third gear helps keep the RPMs lower at cruising speeds. Sold as a kit, it includes six gears, two shifter clutches, and two forks, all crafted from heat-treated and shot-peened nickel alloy steel for exceptional durability. If you are looking to refine the shifting and performance of your early 4-speed gearbox, this Andrews kit provides the precision engineering needed for a long-lasting and reliable transmission.
