GMDDK Diesel Dual Alternator Kit for All GM Duramax 6.6L Diesel Trucks with 270XP High Amp Alternator

The GMDDK Diesel Dual Alternator Kit for All GM Duramax 6.6L Diesel Trucks with 270XP High Amp Alternator from Nations Starter & Alternator is the ultimate solution for powering high-demand electrical systems.

This alternator upgrade kit allows you to maintain your factory charging system for the truck’s essential functions while adding a dedicated secondary source for auxiliary loads. By installing this dual alternator kit, you effectively double your power capacity and gain critical redundancy in the field. The included upgraded alternator utilizes 6-phase hairpin stator technology to provide "brute force" current without the voltage drops typical of standard units. As one of the most reliable high amp alternators available, the 270XP ensures your Duramax can support massive electrical draws without straining your primary battery or engine computer.

When you need more output than the factory alternator or a single High Output Alternator can handle, or want the safety and security of a secondary alternator, a GM dual alternator bracket is the perfect solution. This kit fits GM Trucks such as Silverados, Sierras, and Chevy 2500's with 6.6L Diesel Engines.

Unlike other GM Dual Alternator bracket kits on the market that are cheaply made and poorly designed, our Dual Alternator brackets are precision CNC waterjet cut from solid 3/8" STEEL plate. Then we coat them with a super durable powdercoat finish so they stay looking and working great! With our dual alternator kit, the mounting plate is securely fashioned to the engine with 4, 10MM grade 12.9 bolts which makes installation very simple and secure.
