         Stock alternators and their traditionally weak output levels can lead to frequent battery replacement, failed electronic modules and a wealth of other problems. You can mitigate by upgrading to a more powerful, robust H.O. unit.  
         This high output alternator is a drop in replacement and the answer to your charging problems. It cranks out 200 amps and is a great upgrade to stock vehicles and can effectively support a variety of aftermarket electrical upgrades. 
         The units are well-engineered and buit to last. (they make great starters too!) This unit incorporates a high-grade hardened tool steel rotor shaft that's supported at both ends by heavy duty double sealed bearings. Simply a great upgrade or replacement for a stock rig or one with extra accessories requiring extra amperage.
