These were the identical part number to the ones that came with my GTS. At close to 900 miles, they were still running well. But I figured I'd change them out since I was doing a full bard breakdown anyways (on my GTS). I previously replaced out my old GT bearings with these also. Both installed went great. One small tip. Use a thin film of white lithium lubricant on the outside of the bearing and the inside of the bearing well (the receiver). It will help it seat better.
