33-4205 Steel breather valve spacer .150"

This S&S steel breather valve spacer is a precision thrust washer designed to set the correct end play for steel breather valves. It features a .150-inch thickness and is compatible with late 1977–1999 Big Twin models (excluding Twin Cam) as well as 1936–1999 S&S style cams. These spacers are identical to the OEM-style large-hole replacement spacers. It is critical to remember that steel breathers require steel spacers; you should never intermix steel and plastic components in the breather assembly. This high-quality steel spacer ensures long-lasting durability and proper mechanical clearance within the cam chest.
