well that goes to show that you dont listen to pot heads who think they know what theyre talkin about. okay next question how much would it be for locked differential.
If you're only spinning 1 wheel, you do not have T-lok.
A locking differential is different from a limited slip differential. A limited Slip T-lock diff is what you need. If you do upgrade, get urself a set of 3.73 gears too.
