Yes, much more adjustable & I believe the part underneath that contacts the lower part of the spring eye acts as a ladder bar kinda causing lift & at the same time pushing down on the leaf spring like caltracs. Caltrac has 1 bar that goes across the top of the spring. In addition to the assassin bars & Calvert split monoleafs I have Calvert sliders to finish it off. @ Rat Bastid can fill us in with the finer big word details
