Once the mount locations were determined we returned to Dynatrac, where they began assembling our axles. Dynatrac offers two ProRock 44 housings, one that uses the old-style Dana 44 parts and one that uses the new Jeep JK Dana 44 gears and lockers. We went with the JK version so we could upgrade to a special ARB Air Locker. The axletubes are 31/8 inches in diameter with a wall thickness of 1/2 inch.
