Give your 2011-2016 GM 6.6L Duramax LML the high-quality batteries, alternators, and starters you need to maintain or update the Charging & Starting systems in your truck. XDP has a vast selection of parts to choose from and the right parts you need for the most challenging environments and high draw electrical equipment.
Electronic accessories such as stereo equipment, snowplows, winches and LED lights can exert a higher amount of strain on your charging system. Replacing a basic output alternator with a more reliable, higher amperage XDP HD Series High Output Alternator will remove stress from the charging system. The XDP Gear Reduction Starter comes standard with a compact motor that is more efficient and draws fewer amps while delivering more torque than an OE starter. This increase in torque equates to quicker starting, even for high horsepower diesels.
