Mechman high output alternators · Authorized dealer
Land Cruisers are built to go a long way from help, and owners equip them that way: dual batteries, a fridge, a winch, recovery lights and radios. A Toyota Land Cruiser high output alternator is the foundation for that kind of build. This page covers 1998-2024 Land Cruisers with the 4.7L and 5.7L V8 and the 4.5L diesel, in outputs up to 370 amp.
An expedition build runs a fridge around the clock, charges a second battery, powers camp lighting and radios, and keeps enough reserve for winching. On a long trip with days between towns, the alternator is the only power source unless you carry solar. Every amp it delivers while driving is energy you can use at camp. A Toyota Land Cruiser high output alternator gives a dual-battery system the input it needs to stay topped up.
Land Cruiser fitment comes in four combinations, which the finder at the top of the page sorts for you. The 1998-2002 4.7L and 2003-2007 4.7L use different series. The 2008-2015 5.7L has its own unit, and the 4.5L diesel listed for 2007-2024 has another. Diesel owners should confirm their exact model before ordering. Match your year and engine first, then pick output:
The 370 amp options include a Mechman Elite Series unit for the 5.7L and a unit for the 4.5L diesel. These are Mechman high output alternators, sold here by an authorized dealer.
Most expedition builds use a deep-cycle auxiliary battery from our lithium batteries or AGM batteries. Heavy cable from our amp wiring kits and a Big 3 upgrade let a Toyota Land Cruiser high output alternator deliver its output to both batteries.
