Our take on the OEG Parts New 220 AMP Alternator Replacement For Jeep Wrangler 3.6L 2018-2023, Gladiator 3.6L 20-23 2020 2021 2022 2023 220A 12V

A 220-amp, 12-volt replacement alternator for the 3.6L V6 in 2018-2023 Jeep Wrangler and 2020-2023 Gladiator. It uses a CCW rotation with a solid SD6 pulley and cross-references several Mopar and Mitsubishi part numbers, including 56029765AA and 421000-7221. The 220-amp output is well above the stock unit, which suits owners running winches, light bars, dual batteries or overlanding fridges. It is a direct-fit replacement rather than an upgrade kit, so it installs like the original part.

Questions and answers

Will this fit my 2021 Jeep Wrangler with the 3.6L V6?
Yes. It is listed for Wrangler 3.6L V6 models from 2018 through 2023 and Gladiator 3.6L V6 models from 2020 through 2023. Confirm your engine is the 3.6L, since the 2.0L turbo and diesel use different alternators.
Does 220 amps matter over the stock alternator?
It gives more charging headroom for winches, auxiliary lights, fridges and dual-battery setups. If you run a stock electrical system, the extra capacity is mostly unused but does no harm.
Which part numbers does it replace?
It cross-references 4210007221, MX421000-7221, MX4210007221, 56029765AA and 421000-7221. Match one of these to your original alternator before ordering.
Do I need to upgrade the battery or wiring?
Not strictly, but a higher-output alternator works best with a healthy battery and sound charging cables. If you add heavy loads, check that the wiring and fuse ratings can handle them.
Is it a new or rebuilt alternator?
It is sold as a new alternator, not a remanufactured unit. It is a 12-volt, 220-amp, counterclockwise-rotation unit with an SD6 pulley.
