XDP offers the high-quality alternators, batteries, and starters you need to maintain or update the Charging & Starting systems in your 2017-2019 GM 6.6L Duramax L5P. With a large inventory of electrical components to choose from, XDP has the parts you need for demanding aftermarket electrical equipment and the most brutal road conditions.
Add-on electrical components such as winches, plows, stereo equipment, and LED lights can cause strain on the stock charging system. One of the best preventative maintenance changes you can make is to swap out the aging batteries in your truck, as the average service life of most batteries is only between 4 to 6 years. XDP carries high-quality batteries to replace the stock batteries in your truck and offer higher output to handle more electronic accessories. With increased service life and greater reliability, these batteries are an excellent investment for your truck.
Swapping out the stock output alternator with a greater amperage XDP HD Series High Output Alternator will remove stress from the charging system and increase reliability. The XDP Gear Reduction Starter has a smaller motor that is more efficient and draws less current while providing more torque than a factory replacement starter. Greater torque means faster engine turnover for quicker starting, even for highly modified diesels.
The 2017-2019 GM 6.6L Duramax L5P 2500/3500 models are commonly equipped with a Group Size 48 Battery.
