{"title":"RAM, (2019-2024) 6.7L Cummins, Charging\/Starting, Alternators","description":"\u003cdiv class=\"sds-copy-intro\"\u003e\u003cp\u003eThese are high-output alternators for the 2019-2024 Ram 2500 and 3500 with the 6.7L Cummins. The factory unit makes 180 amps on base trucks and 220 amps on Laramie, Longhorn and Limited diesels. Before you order, know whether your truck has one alternator or the optional dual setup, because the belt and the part numbers change with it.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"sds-copy-guide\"\u003e\n\u003ch2\u003eAlternators on the 2019-2024 Ram 6.7L Cummins\u003c\/h2\u003e\n\u003cp\u003eRam rated the base alternator at 180 amps on both the Hemi and the \u003ca href=\"\/collections\/cummins\"\u003e6.7L Cummins\u003c\/a\u003e. Diesel Laramie, Longhorn and Limited trucks get a 220-amp unit, and a dual 220-amp setup was optional on the Cummins. That is a lot of charging capacity, and the diesel uses it. The intake grid heater draws on the order of 200 amps on cold starts. The two Group 65, 730 CCA batteries need to be brought back up afterward. Diesel models also carry in-duct electric cabin heater elements to speed warm-up, and the truck offers up to three 115-volt, 400-watt outlets plus USB ports. Every one of those loads runs back to the alternator.\u003c\/p\u003e\n\u003ch2\u003eStock output or high output\u003c\/h2\u003e\n\u003cp\u003eOur research does not document an alternator failure pattern for this generation, so this page is about matching output to the way you use the truck, not chasing a known defect. A stock-output replacement suits a truck running factory equipment. A high-output unit makes sense when you add work lights, run tools or appliances off the outlets, or spend long hours idling with the electric cab heat on. Ram itself offered a second 220-amp alternator on this diesel, which shows how much current a working truck can call for. One caution: a bigger alternator does not fix weak batteries. If the batteries are tired, replace both as a matched pair of Group 65 AGM batteries.\u003c\/p\u003e\n\u003ch2\u003eWhat we carry\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/mean-green\"\u003eMean Green\u003c\/a\u003e builds the MG1391SHD, rated at 375 amps, and the 1391 high-output unit.

On 2019-2021 trucks, the serpentine belt is Mopar 5281816AA with one alternator and 5281817AA with two, and the tensioner is a Gates 38285. Check your option code before you order. The Mean Green units are titled through 2023 and the XDP through 2024, so 2024 owners should run the fitment checker.

Dual-alternator trucks use different bracketry and a different belt (5281817AA), and the alternator part numbers differ from single-alternator trucks.

An alternator recharges batteries; it does not bring a tired pair back. The diesel runs two Group 65 batteries, so replace both together as a matched pair.\u003c\/p\u003e\n\u003cp class=\"sds-copy-cta\"\u003eNot sure what fits?
