My current setup is 456-457 SS springs,Procomp truck shocks and snubber.I had Cal-Tracs and Monoleafs but they went flat just like the 3400 springs did.I really liked the way the Cal-Tracs hooked and launched but for a street strip car they were not the solution.I now have a pair of 454-455 3800# springs to install and I was going to install them with "good" Afco adjustable shocks and move them inboard to the framerails.This is the reason for the sliders instead of installing upper spring mounts in the frame.
