So do I have to run with the radius rods?? What will happen if I pull them out???
I never see them in bagged trucks so I am thinking I can get away witout them...

 

you mean strut rods right?

yes you have to have them. they control the caster of your suspension, and without them your lower control arm will flop all around.

if you buy/make triangulated control arms you can eliminate them though.

u must keep it..it helps hold ur lower spndle in place..if u dnt its super wobbly..u dnt se them on bagged trucks cuz they usually have them behind the control arm.custom made ones to help...or like burnie said triangulated arms eliminate them...
