**Premium aftermarket RBI Bearing option custom designed by Doc's Full Bore Outdoor is an upgrade to Argo's OEM outer axle bearing.  This bearing is a higher quality bearing then what Argo uses as the OEM outer bearing for increased life and durability.  All of our aftermarket RBI bearings include dual set-screws.  
  
_RBI Outer Bearing Features:_**  
  
_**\- Staked outer seal prevents grass and mud from popping the metal seal off allowing access to main bearing seals.  This is an issue with the OEM bearing.**_  
  
_**\- Dual triple lipped seals helps prevent water and mud from entering the bearing reducing bearing failure with normal maintenance.**_  
  
_**\- Pre-greased with premium Polyrex EM Grease during production to ensure no dry spots in the bearing for smooth operation and extended life.**_  
  
_**\- Dual race ports at 12 and 6 allow any water or contaminants to be pressed out when greasing.**_
