GMDDK Diesel Dual Alternator Kit for All GM Duramax 6.6L Diesel Trucks with 300XP Alternator

The GMDDK Diesel Dual Alternator Kit for All GM Duramax 6.6L Diesel Trucks with 300XP Alternator from Nations Starter & Alternator is the definitive power solution for your heavy-duty Chevy or GMC rig.

You can finally support your truck's most demanding electrical needs by installing this precision-engineered alternator upgrade kit. This dual alternator kit functions by adding a secondary, independent power source to your engine without removing your factory unit. By utilizing these high amp alternators, you gain the ability to dedicate one unit to your truck's vital systems while the 300XP focuses entirely on auxiliary loads like large inverters or hydraulic pumps. This configuration ensures that your primary starting batteries remain fully charged even when your secondary equipment is under maximum strain, providing "brute force" amperage that single-unit setups simply cannot match.

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.
