Dynatrac’s ProRock 44 Unlimited housing was designed specifically for lifted JKs. The Unlimited has added steering caster engineered in to retain proper steering angles on JKs lifted 2.5 to 6 inches. The shock mounts are moved to provide better shock-to-frame clearance under full articulation. For the JK Rubicon owner, this housing is a direct bolt-in and allows the retention of factory brakes, knuckles, axles, gears, and electric locker. Dynatrac ball joints are much better than the failure-prone OE ball joints and are rebuildable, too.
