1999-2013 GM Vortec 4.8, 5.3, 6.0, 6.2 V8 GM and Chevy Vortec Dual Alternator Bracket

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 DC Power GM dual alternator bracket is the perfect solution. This kit fits popular GM Trucks and SUV's such as Chevy Tahoe, Suburban, Escalade, H2, Silverado and Yukon with the 4.8, 5.3, 6.0, and 6.2L Vortec V8 Gas 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.

How easy is your dual alternator bracket to install?

Here at DC Power Engineering, we believe seeing is believing and that a picture is worth a thousand words. For this reason, we would like you take a look at our step-by-step installation guide with detailed pictures of every single step of the installation process. To view this PDF, please go here.

Why run dual alternators?

What if you had a separate charging system dedicated to the additional accessory load? By running dual alternators you can do just such a thing, and doing so leaves the factory charging system intact doing what it was intended to do, running the vehicle while the secondary alternator carries the additional accessory load. By effectively doubling the available amperage of the vehicle, you can run more accessories with less worry, and all for about the same cost as a single high quality High Output alternator.

We are very proud to say, this dual alternator kit is 100% designed and manufactured in the USA!

What does your dual alternator kit come with?

  • Dual alternator mounting bracket
  • OEM GM idler pulley for the best serpentine belt life. Our competitors use alternator bearings which can cause extreme heat and destroy serpentine belts.
  • Gates Green Stripe serpentine belt.
  • ALL mounting hardware needed to install the bracket and alternator to the vehicle.
  • An alternator excitation harness to turn on the secondary alternator, and this kit will not cause any check engine codes/charging lights
  • Installation instructions
