Sway-A-Way Torsion Bars

It looks like you’re installing the LCA per the factory instructions with the LCA hanging all the way down. With the really large torsion bars that doesn’t usually work. They need to be installed with the angle much closer to ride height, so you may be installing the LCA one hex flat from where it needs to be

That’s especially easy to do with the QA1 LCA’s, because unlike the factory LCA’s they clear the K frame and will hang straight down, making more hex flat positions possible. I did that on my Challenger when I installed tubular LCA’s and 1.12” bars. Followed the FSM and clocked the LCA’s wrong.
