Trucks, Jeeps, muscle cars and minivans

Ram trucks have the widest coverage. The Ram 1500 alternator page runs from 1988 trucks to 2023 models with the 3.6L, and the Ram 2500 and 3500 high output alternators cover the 5.9L and 6.7L diesels and the 6.4L gas V8. Off-road and family SUV owners can start with Jeep Grand Cherokee alternators or the Dodge Durango alternator page, both reaching from the 1990s to 2023. Muscle car builders will find Dodge Charger alternators and Challenger alternator upgrades. The range also includes the Chrysler 300, Magnum, Dakota, Nitro, Commander, Wrangler and Gladiator, and Caravan and Town & Country minivans.

Fitment first, then output

Choosing a Dodge or Ram high output alternator starts with the vehicle finder or a model page, then year and engine. A Ram 1500 alone spans more than a dozen year and engine combinations, and each can call for a different alternator family. Enter your year and engine in the finder at the top of any model page to see which series fits.

Mechman high output alternators for this group come in 240, 320 and 370 Amp. 240 Amp suits a daily driver with one amplifier or a set of auxiliary lights. 320 Amp covers multi-amp audio, a winch or an inverter. 370 Amp is listed for Ram trucks, the Grand Cherokee, Durango, Nitro, Chrysler 300, Charger, Challenger and Magnum, for the heaviest audio and work loads. Minivans and the Wrangler and Gladiator offer 240 and 320 Amp.

Housing and finish

Ram 1500 and Ram 2500 and 3500 pages include billet units in Black or Natural, machined from solid aluminum for extra rigidity. Most other vehicles in this group use a standard housing in a Natural finish, which suits the majority of builds.

Supporting upgrades

Bigger output needs a path to the battery. Start with Big 3 and amp wiring kits, then add capacity from our batteries. For plug adapters and voltage regulators, see alternator harnesses and regulators. To compare every make, browse all alternators.
