On my bloodyknuckle offroad radius arms (cage offroad)they use huge heims the size of soda cans... they seem to do real good so far, on the highway anyway. I didnt get to try it out on the trail so i cant help you with that. Was said that with the heim ull get more articulation with them. The arms dont connect right to the axle tho they have poly bushings on the axle mounts.
