Mechman high output alternators · Authorized dealer
Trail Jeeps spend a lot of time at low engine speed with heavy loads switched on: light bars at night, an air compressor after airing down, and a winch when the line comes off the drum. Each Jeep Wrangler & Gladiator high output alternator on this page matches our fitment data, from early 2.5L and 4.0L Wranglers through current 3.6L models.
A winch pull draws heavily from the battery, and the alternator has to replace that energy before the next obstacle. Crawling keeps engine speed low, so the charging system works at a disadvantage just when the light bar, rock lights and compressor are all on. A Jeep Wrangler & Gladiator high output alternator gives the battery more support on that kind of trail day. It helps on the road too, where a sound bar or an amplifier for a subwoofer under the rear seat adds another load.
Fitment splits by engine and year, which the Make, Model, Year and Engine search above handles for you. The 1991-1998 4.0L and the 1991-2002 2.5L share one series. The 1999-2006 4.0L uses a later series, the 2007-2011 3.8L has its own unit, and the 3.6L covers 2012 through 2026. Match your year and engine before choosing a Jeep Wrangler & Gladiator high output alternator, since each span uses a different design.
Mechman high output alternators for these Jeeps come in 240 and 320 Amp, in a natural finish. Available output depends on the year span, so check the amperage filter once you pick your Jeep.
Pair either one with a winch-ready AGM battery and heavy cable from our Big 3 and wiring kits. More Jeep fitments, including the Grand Cherokee, are in the Dodge, Ram, Jeep and Chrysler collection.
