Trust me. We know, because we asked for the rough stuff and came out of it with no damage to the sheetmetal or body parts – ours, or the Jeep’s. Though all Wrangler Rubicons have front and rear electronic locking differentials, we tackled Cadillac Hill without ‘em, activating only when we felt the urgent need to do so. This way, we could see first-hand how well the system worked. All told, we activated the lockers around five times over six hours of driving, and only to assist us in navigating a tough patch of rocks or a slippery corner.
