Enhance the charging system in your 2011-2019 GM 6.6L Duramax with the XDP Wrinkle Black HD High Output Alternator XD350. While many Duramax owners upgrade their truck for performance, the charging system is often overlooked until there is an issue.

Aftermarket accessories such as off-road lights, aftermarket horn kits, on-board air compressors, snowplows, stereo equipment and other electronics will overload your factory charging system and demand more than what the factory alternator can provide.

The XDP HD Series High Output Alternator increases the output of your factory charging system giving you the ability to reliably run your high-draw electronics while alleviating the strain on your charging system.

The XD350 features an OE style decoupler pulley that helps synchronize the serpentine belt to improve efficiency, while also reducing the noise/vibration/harshness (NVH) and increasing accessory drive component life.

Each XDP HD Alternator comes with an ultra-durable wrinkle black coating and is pre-tested for an easy bolt-on installation.
Features:

• 245 Amp Output
• Bolt-On Upgrade
• OEM Style Decoupler Pulley
• 100 percent Brand New, No Core!
• Fits: 2011-2019 GM 6.6L Duramax
