About This Product
MCS stock-style front exhaust rocker arm for Ironhead Sportsters. It replaces OEM 17394-57A. It fits XL models from 1957 to 1985. The pad and bushing wear out over time. Worn rockers cause valvetrain noise. Replace it when you are rebuilding the top end. This keeps the valve timing right. This is the front exhaust position.
Manufacturer part number: 904845.
