About This Product
S&S steel breather valve and spacer set. Sold as a kit. It fits 1948 to early 1977 Big Twins. The elongated breather holes extend the vacuum pulse to scavenge more oil from the top end. That helps both stock 74-inch motors and large-displacement stroker builds. The kit includes spacers to set end-play correctly in the case. It replaces worn plastic or steel factory breathers. Fit this if you want better oil control and fewer leaks.
Manufacturer part number: 33-4253.
