What does EBS mean on a Polaris RZR?
Used EBS secondary and one way bearing for those models listed as having EBS on it. All vehicles have engine braking down to a certain speed or RPM but the EBS we are talking about is when the speed drops down to a point the primary disengages and it starts to free wheel. There is two levels of EBS and the natural engine braking is on all of them.
Where is the EBS notch on Polaris engine braking?
To see a helix click HERE and the helix on the left in the picture has a EBS notch, the one on the right does not. That would be for someone who wants to remove low speed engine braking for say a racing application.
What kind of EBS does a 2012 Polaris 570 have?
2012 570’s have EBS secondary, actually the exact same one as a XP 900 and the two way bearing. 2013 570 LE Models have the EBS secondary and one way bearing. I “think” all RZR 4 800’s have Rapid Reaction secondary and two way bearing.
What kind of braking system does Polaris have?
Full On EBS, Most Braking: These vehicles have the EBS secondary and a one way bearing in the primary from the factory. Other than the 09 S RZR 800, any vehicle that comes with a one way bearing, those bearings fail rather often.

What kind of bearing does Polaris engine braking use?
Polaris has not done us much help by using a combination of different clutching components on different models and different years. Same primaries but two different bearings in them, one has a one way bearing for full one EBS and one has a two way bearing in it.
Is the EBS secondary and one way bearing primary freewheel?
Vehicles with the EBS secondary and one way bearing primary have what we call “Full” EBS and do NOT freewheel ever. They have braking to a dead stop on the engine.
