Charging & Starting

2010-2018 Dodge Ram 2500 & 3500 6.7L Cummins Heavy-Duty Starters, High-Output Alternators & Electrical Components

Eliminate performance-robbing voltage drops, guarantee rapid engine turnovers in extreme sub-zero temperatures, and supply your electrical grid with unyielding power with premium 2010–2018 6.7L Cummins 4th Gen charging and starting components from Full Force Diesel. The electrical architecture on a 4th Generation Ram HD truck is subjected to immense structural and mechanical strain. Spinning over a massive, high-compression 6.7-liter inline-six diesel engine requires an incredible amount of initial cold-cranking amperage, while supporting late-model cabin electronics, heavy-duty lighting, aftermarket winches, and high-pressure fuel pumps can easily push the factory charging system to its absolute limits. Upgrading to engineered, heavy-duty starting and charging hardware ensures your dual-battery network remains fully charged and ready to work.

High-Output Alternators: Keeping Pace with Heavy Accessory Loads

The factory alternator is frequently overwhelmed when you begin adding high-draw performance accessories or demanding work gear to your common-rail truck:

• Overcoming Charging Deficits: The stock charging system is designed to handle standard factory parameters, but it leaves very little overhead. If you run dual aftermarket fuel pumps, custom stereo systems, commercial snowplows, or auxiliary lighting grids, your voltage will drop significantly, placing a severe burden on your batteries and electronic control modules. Upgrading to a premium high-output alternator delivering up to 250 or 320 amps ensures stable, clean voltage delivery across your entire chassis, even at a hot idle.

• Heavy-Duty Internal Engineering: Performance alternators feature massive internal upgrades compared to standard auto-parts-store replacements. Utilizing heavy-duty hairpins, dual internal fans for advanced thermal management, and premium oversized bearings, these charging units resist heat soak and failure under continuous heavy loads, ensuring your truck’s electrical grid stays perfectly balanced.

High-Torque Starters and Heavy-Wall Wiring: Bulletproof Crank Synchronization

Ensuring immediate, reliable combustion ignition requires a robust starting system capable of spinning the heavy internal rotating assembly without hesitation:

• Gear-Reduction Replacement Starters: When factory starters age, their internal bushings and brushes wear down, causing them to draw excessive amperage while turning the engine over sluggishly. Our heavy-duty replacement starters utilize advanced gear-reduction architectures that multiply rotational torque while drawing less net power from your batteries. This design spins the micro-polished crankshaft faster to build compression instantly, eliminating extended crank times and saving wear on your valvetrain.

• Heavy-Gauge Battery Cable Upgrades: A high-torque starter or high-output alternator is only as effective as the wiring harness connecting it to the batteries. Factory battery cables use thin-gauge copper that corrodes internally over time, creating massive electrical resistance. Upgrading to custom heavy-gauge copper battery cables with sealed, tin-plated copper lugs ensures maximum current flow, eliminating intermittent starting issues and ensuring your diagnostic network receives a clean, uncorrupted power supply.
