A radius arm axle tends to have a more torsion bar type action as opposed to a four link which will be looser on the articulation movement. The radius arm setup also changes pinion angle and caster quite a bit more through travel over the 4 link. On the 4 link pinion angle and caster remains fairly constant. Was looking at radius arm from Blitzkrieg as well as 4 link by ORD. I chose the four link over the radius arm myself. Am running a sway bar as well which is added cost.
