Wrinkle Black HD High Output Alternator For 2011–2019 GM 6.6L Duramax
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 trucks for performance, the charging system is often overlooked until problems arise. High-demand accessories such as off-road lights, onboard air compressors, aftermarket horns, snowplows, sound systems, and other electronics can quickly overwhelm the factory alternator.
The XDP HD Series High Output Alternator increases the output capacity of your charging system, allowing you to reliably power high-draw electronics while reducing strain on your factory electrical components. Designed as a direct bolt-on upgrade, it provides improved performance without requiring modifications.
The XD350 features an OE-style decoupler pulley that helps synchronize the serpentine belt for improved efficiency while reducing noise, vibration, and harshness (NVH). Each alternator includes a durable wrinkle black coating and is pre-tested for a straightforward installation.
