New EBS-type aftermarket primary clutch and secondary clutch both made as OE style replacements. This is the 1-way bearing aka EBS primary clutch, and the tied type secondary which is an upgrade on many years below that came with a Rapid Reaction secondary clutch originally. These are specific for 08-14 RZR 800, 2010-2014 Polaris Ranger 800 (all packages), and all 2005-2014 Sportsman 800. We have spent a good amount of time testing and revising these clutches before selling them to make sure they have smooth and responsive performance on RZR 800, Ranger 800, and Sportsman 800. These come correct for ready-to bolt-on and ride with weights and spring already in it! This setup came originally on 2005-2009 Sportsman 800 and 2009 RZR 800-S so the set stock spec replacement on those years but is also a bolt-on update ( adds additional EBS from primary and stronger secondary design) on all the other years listed. FITMENT is all models below: 2005-2009 Sportsman 800 (original setup on both sides) 2010-2014 Sportsman 800 (upgrades to Tied secondary and EBS primary) 2008-2009 RZR 800 (original Type of secondary but upgrades primary to EBS) 2009 RZR 800 S (original setup on both sides) 2010-2014 RZR 800 (upgrades to Tied secondary and EBS primary) 2010-2014 RANGER 800 (upgrades to Tied secondary and EBS primary)
