Long story short. 2020 HL 4 seater on 4 inch portals with 37’s. went to change front diff fluid and when I pulled plug noticed shavings in oil and water in diff. I change almost every ride and never had an issue with water or shavings. Found pinion seal was dripping. No biggie, I punch out the roll pin, and notice that the input shaft has side to side play in it. that can’t be good. Rzr has less that 300 miles on it. I want to go ahead and replace it with a SuperATV one. Then when I have time rebuild the stock one and keep on shelf. I took to dealer to try and have it covered, got denied. So I sold my extended warranty back for 2300$ and I’ll use about $1000 of that for new diff. Also how do I find out which diff I actually need. Where do I find those numbers? what could have caused such a premature failure? I’ve noticed a slight vibration under floorboard when in AWD. Drive shaft bad? The u joints are tight with no slop. Just input bearing FAIL.
Torque against input bearing. Portals big tires something might break. Some said 35s will break front differential. I would have had 2 sets of tires rims for warranty.
Not sure if the RS1 diff will fit a 1000 but I would look in to the conversion. My buddy did one for less than 1500 bucks on his 2017 XPT4 it was a good day project. The new billet dif brackets made the conversion pretty easy.
As far as I know only XP PRO, TURBO S, RS1 only get the RS1 diff. Normal XP turbo does have an upgraded diff but not to the extent as the RS1 diff. BRAND NEW RS1 FRONT DIFF W/ OPTIONAL BRACKET KIT
Brand new RS1 front diff
Turbos no need for new axles, 1000XP must utilize turbo axles.
Will fit 2015-2016 Highlifter Models
******This unit does not fit 2017-2019 Highlifter and Rock and Trail Edition. We have done the research.
Optional bracket allows for winch mount!
The end all your problems, the king of Differentials. Polaris knocked it out of the park with this engineering spectical
