I saw that Ranger in Moab. Takled to the owner for and invited him to the site. The raduis arm setup is sweet! Its hard to tell from the photos, but the right arm uses Johnny joints on both ends. The left arm has a fixed mount at the axle and a Johnny joint at the frame. The owner hadn't tested it when I was talking to him (he had only finished it the day before), but he did say that he was going to have trouble with the driveline due to the increased flex of the new suspension. The truck is running a EB Dana44, 9" combo with a 302, C-4, Dana20.
