Replace that heavy and weak cast aluminum primary clutch cover with this billet aluminum version. CNC cut from 6061 aluminum, this cover is a work of art and works great too. Lighter and stronger then stock and you will notice and better top end engagement. Also has a small fins to allow for slightly better cooling. Installs just like the stock unit, no modifications necessary. Replaces pretty much every Polaris ATV/ UTV clutch cover from 1996 and up. Does not fit 2016-19 RZR Turbos and RS1
