Increase the output of the charging system in your 2011-2019 GM 6.6L Duramax with the XDP HD High Output Alternator Wrinkle Black XD350. 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 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 includes the results of pre-testing for easy bolt-on installation.
