About This Product
These sprocket shaft bearing retaining rings are essential for any bottom-end rebuild on a classic Harley. Sold as a pack of 10, they are a direct replacement for OEM 24779-55 and part number 508603. These rings are designed to fit 1955 to 1968 Big Twin models, ensuring the sprocket shaft bearing stays exactly where it belongs. As a mechanic, I know you cannot cut corners on fasteners like these; they need to be precise and durable to handle the stresses of a Panhead or early Shovelhead motor. Keep a pack in your drawer so you are always ready for the next engine job.
Manufacturer part number: 508603.
Fitment
55-68 Big Twin
