The alternator in your Jeep Wrangler performs two vital tasks. First, it recharges the battery, which is used to start the engine. Second, it provides electrical power when the vehicle is running. Because off-roading enthusiasts often install auxiliary lighting systems, such as light bars and brackets, they use more electrical power than most drivers. Not to mention the fact that driving on challenging off-road terrain requires higher amperage to maintain a consistent performance level. The high output alternators we sell have enough power to run the electrical system of any Jeep Wrangler without draining the battery or affecting performance.
