About This Product
These 5/16-inch diameter steel balls from MCS are essential for several critical assemblies on vintage Harleys. They are used in the head cups for 1952 to 1977 K-models and XL Sportsters, as well as all Springer front ends from 1929 to 1973. Additionally, they are used in the clutch ramp for 1971 to early 1984 XL Sportsters. Whether you are rebuilding your steering neck or refreshing your clutch release mechanism, having high-quality, uniform bearings is key to smooth operation. This set is sold as a pack of 25, providing plenty of replacements to meet the requirements of OEM part 8860.
Manufacturer part number: 507810.
