About This Product
JIMS standard steel breather valve with an elongated rear oil hole. The longer hole improves crankcase vacuum on large-capacity performance engines. It fits late 1977 to 1999 Big Twins, excluding Twin Cam motors, and replaces OEM 25313-77C. It also works with late 1979 to 1999 style steel breather valve thrust washers. Fit this instead of the stock plastic breather if you want better oil scavenging under high loads.
Manufacturer part number: 2337ST.
Fitment
L77-99 Big Twin (Excl. Twin Cam)
