Increase the output of the charging system in your 2001-2007 GM 6.6L Duramax with the XDP Wrinkle Black HD High Output Alternator XD355. The Duramax engine is a known powerhouse that is easy to modify, but the charging system is often forgotten about until there is an issue.

The demands of popular add-on accessories like aftermarket horn kits, on-board air compressors, off-road lights, plows, stereo equipment, and other electronics can quickly exceed what your factory alternator can support.

The XDP HD Series Alternators increase the output of your charging system and allow your truck to keep up with any aftermarket upgrades you choose to install. Whether you're out plowing snow all night, or need to light up the trail with your off-road lights, the XDP HD Series Alternators have you covered!

Each unit features an ultra-durable wrinkle black coating for enhanced underhood aesthetics and corrosion resistance. The XD355 comes pre-tested and ready to install using factory mounting locations, factory belt, and existing connections.
