About This Product
This Colony rocker box bolt kit is an essential reproduction for 1936 to 1947 Knucklehead engines. These hex bolts are meticulously machined from solid steel bars to match the original factory specifications, rather than being simple modern fasteners. The kit comes finished in zinc and includes the necessary lock washers for a complete installation. It replaces the upper and lower bolts along with the spring washers, corresponding to OEM reference 071 and part number 929723. Sold as a kit, this hardware provides the strength and authentic appearance required for one of Harley-Davidson’s most iconic powerplants, ensuring your Knucklehead remains period-correct down to the last bolt.
Manufacturer part number: 8779-12-Z.
