THE KWI AO BASE CLUTCH KIT IS DESIGNED FOR THE 2017+ CANAM X3 120HP, 152HP, AND 172HP MODELS AT STOCK HP LEVELS OR WITH ANY TUNE OR FUEL THAT INCREASES BOOST/HP AND STILL USES THE OEM TURBO. THIS KIT COMES WITHOUT A HELIX AND CAN USE THE OEM HELIX THAT CAME WITH YOUR VEHICLE. FOR THAT EXTRA BOOST IN PERFORMANCE YOU CAN OPT TO PURCHASE THE KWI DR CUT HELIX AND ADD TO YOUR AO BASE KIT (DR HELIX IS NOT REQUIRED BUT WILL ACCELERATE HARDER AND BACKSHIFT QUICKER THAN OEM HELIX)
