I've run Tri-City Launcher springs with and without Cal-Tracks and then Cal-Tracks with the split-leaf. By far the Cal-Track bars with the split leaf was the best move for me. You will reduce your leaf spring weight by about half when you go from a multi-leaf spring (especially if you had a stiff / race multi-leaf such as a SS Mopar spring) to a split leaf from Calvert. That weight savings can be placed right back in the trunk where it does the most good.
