Dodge Ram Promaster Dual Alternator Kit with 280XP High Amp Alternator for 2014-2021 3.6L Gas Engines using AGM Batteries

• Robust Power Delivery: The 280XP unit provides massive amperage even at low speeds, ensuring your AGM house batteries stay topped off during city driving or idling.
• Stand-Alone Reliability: This system operates independently of your factory charging circuit, protecting your vehicle's sensitive ECU and starting battery from heavy accessory loads.
• Precision Fitment: Every bracket is laser-cut and powder-coated for a perfect match with the 3.6L Pentastar engine, ensuring long-term belt stability and performance.

• Eliminate voltage sag and flickering lights by providing a dedicated current source for your living space.
• Enjoy a quieter camping experience by relying on silent, engine-based power generation instead of a generator.
• Achieve rapid battery replenishment that outpaces solar panels, especially during winter or overcast travel days.

Dodge Ram Promaster Dual Alternator Bracket Kit

(Using only AGM Batteries)

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 Nations dual alternator bracket is the perfect solution. This kit fits 2014-2021 3.6L Gas Engines using AGM Batteries.

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.

What does your dual alternator kit come with?

• Dual alternator mounting bracket
• 280XP High Amp Alternator
• 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.

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!
