This cover comes with 4 new mounting bolts, o-ring, and two 1/4NPT x 6AN fittings OR barbed fittings - its your choice. The cover has a 1.25" height without fittings. This was designed for my Rhino and they work so well I put them on the site for your Rhino to enjoy being able to breath without spitting oil everywhere. Super Trick and EASY to install. Both lines can go to one breather filter, or two separate filters(sold separately) - or you can do it like my Rhino, one line goes to my original Crankcase breather hose and the other line goes to a Breather/filter - works AWESOME! No more losing your precious oil by having it just blow(plus the suction from your intake) into the airbox and then on the ground - keep that oil in your engine! This little goodie will let the oil drop right back to the top of your head where the cam and rockers are - and thats good...Will fit Race Raptors and Rhino 660's.
