Which Secondary do I buy? Hunterworks offers two different secondary clutches, one with a helix and spring and one without either but both have our HD rollers in them to replace the OE square pucks. We are now offering a complete secondary for the XP 1000 RZR and for the 2016-2022 900 RZR All models for those who have ruined their helix and spring. We had these helixes made to be the same upshift and backshift as a stock one therefore even though the spring and helix are not Polaris parts on the XP 1000 but they are the same for all intents and purposes. The one without a helix or spring works on more models, including Generals, 1000S, 2017 Ranger XP 1000 etc, than does the complete one due to Polaris using the same clutch on so many models where the helix and spring are only difference. See complete listing on item description. The 2016 XP 1000 RZR is only available without the helix and spring due to Polaris not doing the clutching correct in 2016 so the only way we sell it is is without a helix and spring. If you need that, then only way we sell it is, is by you buying a Dalton clutch kit so you have correct clutching. If you want a complete stock, we do not carry that for a 2016 model XP 1000 RZR. The models each clutch works on is listed on each of the two product pages. I know it is a touch confusing but if your model is listed on either one it works, if not it won't. LOL If you are planning on adding a Dalton clutch kit to either when you buy, you might want to email me, todd@hunterworks.com too to make sure we get it all right. Todd |
