The Release Bearings that we supply are new, this part of the clutch is not remanufactured, they are of OE specification.  They range from the old Carbon Bearings, Release Bearings, Pull Type and lastly the most modern the Concentric Slave Cylinder, also known as the CSC.   

These bearings can all be purchased through us as a single item.  But of course, we recommend that when changing any part of the clutch you should replace the whole unit.

Unfortunately, we can only guarantee clutch kits and not items purchased individually, as you are placing them with old and worn parts.
