You have to take one bolt off the back of ladder bars, top bottom no matter. You can’t get the car balanced right without doing that, all four corners have to move, I would do all the shocks too.
I did pull the front shocks on case there was an issue. Didn't think there would be since they just came back from Afco. Removing the ladder bar bolt would remove all preload. I wanted to know how much it had just for reference. It'll never make a pass with the bars neutral. So what it scales with no preload really doesnt give me any info. It launches straight and level.
