are we talking about the bolt on underrider bars that attatch using the bolt going through the front bushing in the leaf?? and have a bar going across the top of the leaf spring?? if you pull on a calltrack bar, it will just lift the bar from the leaf and allow the pinion to nose down..... which is what happens under breaking... they are great for drag racing... and as you yourself put it hook 700 hp on NOS... my point wasnt hook, but breaking..
