About This Product
Colony cylinder base nut kit fits 1957 to 1985 XL Sportster and 1929 to 1973 45 inch Sidevalve models. The kit contains hex nuts with a zinc finish. These fasteners take the heat and torque at the cylinder base. Replace the old hardware during a top-end rebuild on an Ironhead or 45 inch engine to maintain proper clamping load and a reliable seal at the jug.
Manufacturer part number: 8107-16-Z.
