 Same here. Cal-Tracs or Assassin Bars (very similar to Cal-Tracs) are as good as it gets for leaf spring traction. Both are about the same as far as ground clearance. I've never had a clearance issue w/ mine. What springs did you run with your Assassin Bars? I have Cal-Tracs. The Calvert mono springs handle just fine on the street. I've out a bunch of miles on mine. I'm sorry, I misread. I would like to run Assassin bars, but I have Super Stock springs now. I'm not sure if it would be wise to run those with the Assassins or not. I know you "can", the question is "should I"! I haven't decided against Caltracs, I just would like to run Assassin Bars. (I already have the Dana) The Assassin bars work on the same principle as Cal-Tracs, just have a slightly different design and more adjustments. I would not run them w/ SS springs...get the Calvert mono springs.
