These helixes make the RZR more responsive in all conditions and are much less prone to RPM and top-end power loss in higher load conditions (sand, snow, mud etc.) as well as at hi gher elevations or when running larger, more aggressive tires. EBS Helixes have a less aggressive EBS notch than the factory helixes and when used on 570/800/900 models with factory EBS or all RZR XP 900/1000 models, they will reduce the aggressive nature of the stock Engine Braking System. Non-EBS Helixes are made without an EBS notch and when used on 570/800/900 models with factory EBS or all RZR XP 900/1000 models, they will let the RZR freewheel more readily than stock. These helixes are a good combination for customers that want less engine holdback when off the throttle in sand, most racing applications or jumping long distances. Non-EBS helixes are not recommended for trail use as engine braking is greatly reduced. Note: Many RZR models came from the factory with a TEAM Rapid Reaction Secondary Clutch that had the helix cast into the moveable sheave. On these models, the helix is non-replaceable (2009 and newer Standard RZR as well as 2010 and newer RZR-S, 800 RZR-4 and 2012-17 RZR 570, 2015 900 Trail/S/XC/RZR-4 (except 570/800/900 models with factory EBS). These models must use the TEAM Tied Clutch. Show more
