This upgrade comes with weight and springs already in it ready to mount up and use! It is also a lot smoother engaging clutch on take off and does away with the problematic EBS setup that came stock. It is a P90XT clutch with the same heavy duty design that comes on the 16-20 RZR Turbo.
It does away with the failure prone EBS design and casting flaws. This will get you in the slightly higher rpm power band you want for performance if using on medium to fast pace trail riding or for sport.
Only downfall on these has nothing to do with function of it but rather a sound. They tick at idle (when under 2200 rpm) by design for same reason the OE RZR Turbo clicks at idle. It is becuase the spider moves freely in the clutch basket by design unlike the oe clutch that its replacing. IN 2018 POLARIS DID A SPLIT YEAR and it FITS the NON CREW models in 2018.
