my friend's old ford ranger does not flex..it doesn't have a sway bar that I can spot...there your normal three bars when you look at the front of his truck, the tie rod, track bar and drag link...I assume that none of these should be keeping it from flexing?? I guess the coils could just be extremely stiff coils and it wouldn't surprise me, but I know his truck could do stuff easier if it would flex, so I just wanted to see what ya'll had to say
