S&S, breather valve and steel spacer set. +.030" OD

With steel breather valve shim set for correct axial play. Oversized +.030" steel breather valve. Used to salvage worn or damaged crankcases. Suitable for stock or high-performance replacement.
Note: JIMS has a reamer tool for +.030" breather holes, available as 978343.
Note: S&S breather valves come with elongated breather holes to increase the duration of the vacuum, allowing more oil to be extracted from the cylinder heads. This has no downside on any model year, whether stock or Big Inch engine.
