High Output Alternator for RAM 5500 (2011-2014) 6.7L

Heavy-Duty 350-Amp High Output Alternator for 2011-2014 RAM 5500 (DP)

What it Does: The 350-amp High Output Alternator replaces the low-output factory charging unit on the 2011-2014 RAM 5500 to deliver stable 12V electrical current and prevent voltage drop under severe auxiliary loads.

The Stock RAM 5500 Charging Limitations

Commercial-duty DP platform trucks run high-demand auxiliary equipment such as hydraulic lift gates, commercial snow plows, service body cranes, and heavy winches. The OEM alternator (interchange 04801768AA) fails to supply sufficient amperage at engine idle, dropping system voltage below 13.0 volts under continuous duty cycles. This excessive thermal stress degrades the internal diode trio, causes brush arcing, and induces stator coil varnish breakdown, resulting in drained dual-battery banks, flickering work lights, and severe ECM voltage drop.

The Engineering Solution

Engineered specifically for the Cummins 6.7L ISB turbo diesel, this 350A drop-in alternator incorporates dense, heavy-gauge hairpin-style copper stator windings paired with a precision dynamic-balanced rotor. High-temp, double-sealed NSK bearings prevent front-bearing failure caused by severe serpentine belt tension, while a heavy-duty internal bridge rectifier with oversized heat sinking efficiently dissipates thermal soak. The unit mounts directly to factory brackets using standard OE bolt points, clocking, and plug configurations for zero wiring harness modifications.

Frequently Asked Questions & Fitment Warnings

Does this fit the DP 5500?

Yes, this is a direct fit for the 2011-2014 RAM 5500 equipped with the Cummins 6.7L ISB engine.

Should I upgrade my vehicle's charging cables during installation?

To safely carry full 350-amp output and minimize resistance, upgrading the alternator-to-battery positive wire and primary chassis ground to 1/0 AWG cable is strongly recommended.

The RAM Work-Ready Standard

Commercial fleets rely on heavy-duty RAM platforms for relentless towing, hauling, and auxiliary power generation. Upgrading to a 350-amp alternator delivers the reserve charging capacity and continuous reliability necessary to keep commercial electrical gear functioning flawlessly on grueling jobsites.
