Roger,
Yes im using the Kit black ones, i have had the car since october 2006 and its been used indoors and out, including dusty/sandy/wet tracks so it had a fair bit of abuse and i only ran the diff for one meeting, so i have had the 1 way in for a year now. I have never even opened up the front diff casing or had the need to re-build/replace the driveshafts.
The BJ4 doesnt actually feel like its using a one way, it feels very neutral yet positive and never snatches.
All this may be because i drive like a touring car girl though
