The rear Currie RockJock high-pinion 60 has 5.13 gears and an Eaton Detroit Locker. The offset differential hearkens back to Jeep's good ol' days (yeah, we know it's on the opposite side). By doing this, the diff travels up and over the rocks when the tire does. Also, with the front and rear differentials in line with each other, the same rock can be missed without jockeying the vehicle around. The Atlas transfer case has a center output, causing a horizontal driveshaft angle as well as the usual vertical angle. Walker reports he doesn't have any driveline vibration, though.
