Four link?

Once a four link is installed and adjusted 95% of the people never adjust it again . They are terrible on the street because the rod ends are constantly being pounded out and they are noisy . the same goes for ladder bars . Today leaf springs and/or Cal-tracs can perform the same function without cutting the crap out of the car . Consider NHRA, A/Stock stick or automatic that are in the 9 second time slot with leaf springs . I you want to hook hard at the track with leafs add a pinion snubber . Still works great after 50 years .
