Great kit for a leaking counter shaft
Did the trick in sealing my counter shaft, sprung a gnarly leak that was basically a solid stream of oil when my engine was running, over a year later and lots of miles and the seal is still holding just perfectly. Great price and product worked flawlessly.

All Balls Counter Shaft Seal Kit
My KTM had the automatic chain oiler running at full tilt. It was infuriating, and made a mess everywhere. When I pulled the old sleeve, I found it had been ridden so much the seal wore a .2mm groove into it. This kit went on in about 15 min and using the thickest provided O-ring it does not leak at all. Spectacular product/value for KTM countershaft leaks. -m-2008 KTM 200 XC-W--

Very Satisfied
This All Balls Seal kit for my KX450F included everything needed and all parts fit perfectly. Having a new bushing is great if the stock one is stuck and you ding it up trying to get if off (be sure to replace the O-ring when changing the countershaft seal). Very happy with this kit and I would definitely recommend.
