Power to Handle Any Load!

Tuff Stuff Tuff Mudder Alternators are specifically designed for your Jeep Wrangler JK and provide up to 50 percent more amperage power than a factory-style alternator. These quality alternators feature large copper windings, giant diodes and premium-quality ball bearings for maximum output and dependability. High-amp alternators provide charging at very low RPMs and come complete with a 6-groove pulley and a large internal cooling fan to prevent overheating in extreme conditions.
