About This Product
S&S steel breather valve and spacer set with +.030" oversize outside diameter. Fits 1948 to early 1977 Big Twins with a worn or damaged crankcase breather bore. You will need to re-machine the hole with a standard reamer. The valve has elongated breather holes. That extends vacuum duration and pulls more oil from the cylinder heads. The kit includes steel spacers for setting end play. Use it on stock motors or Big Inch builds. Sold as a set.
Manufacturer part number: 33-4263.
