Mounts up and works on 2017-2018 Polaris Ranger 1000 XP as it comes but weights and springs that come in it let it rev up higher than the oem did. This might 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 OR if you use your Ranger more for slow /work and, or towing you might want to swap your OEM weight and springs in for low rpm torque like the way it came.
FITMENT: FITS ALL PACKAGES OF 2017 Ranger 1000 XP .* IN 2018 POLARIS DID A SPLIT YEAR and THE CREW of 2018 this fits BUT NOT the standard. If you got a 2018 the part number this replaces is 1323317.
