I would venture a guess that you are running synthetic oil with that clutch? A big no-no........your clutch will slip like crazy if you are running synthetic in the Raptor - switch to a cheaper, regular oil before you spend any money on another clutch and see if that helps you......give the old oil a chance to get out of your clutch plates and the new oil to get in..........it's worth a shot, anyway. This happened to our Raptor and the cheaper oil fixed the problem right away - those Barnett's are good, shouldn't be going out so soon......

 

Oh - you might also try stiffer aftermarket springs, too - before you do anything else....
