My 12 bolt still works fine after 14 years of rolling burnouts, donuts and 180's at stop lights. Rebuilt my eaton about 3 months ago. Only the clutches crap out and they're only $120 to replace if you do it your self. Stock rear and drive shaft behind a 741hp small block. It doesn't grind or whine or lurch around corners. It just reverts to a one tire fryer every other year. 4.10 and posi = smiles by the 1/4 mile
