Rebuilding the rear diff on a 2013 Outlander 650 XMR. It took 6 months to get the ring and pinion set and the first thing I noticed is the pinions are different. I just called the shop and they swear this is the right part number for this atv. 703500873 is the part number. First off, the new pinion spins rough if I just place it in the needle bearing and spin it as opposed to the old one which feels smooth and nice.

In the picture below the new is on the left and the old on the right. The top shoulder is cut different where it butts up to the end of the needle bearing and the you can also see the teeth on the left are straight across the top and the one on the right are cut at an angle.

And you can see the one on the left has a smaller bolt hole. Anybody know what's going on here? There are little plastic pieces on both sides under the rear fenders that say G2 and the diff looks like what a G2 is from pics I have found online. So I have to assume this is a second gen rear end.
