These rocker cover assemblies were developed to provide a high tech look while reducing the high cost of a similar product machined from billet aluminum. They can be used on all years and models of the Evolution engine regardless of whether the engine vents through the crankcase or the cylinder heads. The one way breather valve has been upgraded from the OE umbrella type to a much more efficient flapper type and is also located higher in the cover. Installation of covers on OE height and most comparably sized engines can be performed without removing the engine from the frame. Sold as an assembly for front and rear heads.V-FACTORReplacement Gasket & O Ring Seal Set (includes 10 pieces for 2 rocker covers)Fits Big Twin Evolution 1984/1999 & Sportster 1986/Later(Imported)
