Quote: You might be hitting those bars too hard with your 4 speed and weight, and either the diagonal link or ladder bar has to bend at some point. I think your diagonal link won the feats of strength fight back there.
It's awesome you're using the car again after a multi-year hiatus.
If the rear end is square in the car the diagonal link shouldnt be taking much if any load(if the preload is correct)... I think its just too wimpy of a bar set up for the force being applied... the bars I put in the Rampage are 1 1/8 X .095 wall moly being that its a street/drag car
