Mechman high output alternators · Authorized dealer
Lexus owners keep their cars a long time, and an older LS, GS or SC often ends up as a project: a modern head unit, an amplifier behind the rear seat, or a full show system. LX and GX owners load up for overland trips instead. Every Lexus high output alternator we list is collected here for models from 1990 on. Use the vehicle finder to match year and engine.
The Lexus SC300 alternator page covers the 1992-2000 3.0L coupe, a popular base for audio and performance builds, and the GS300 page spans 1993 to 2006. Owners of V8 sedans should check the LS430 for 2001-2006 and the GS430 for 2001-2007. The ES, IS, LS400, SC400, SC430 and other GS models are listed as well, each on its own page. On older cars, a new high output unit also replaces a factory alternator that may have decades of wear on it.
The LX470 from 1998 to 2007, the 2008-2015 LX570 and the 2003-2009 GX470 are covered for owners who travel far from pavement. Those trucks often carry a second battery, a fridge, recovery lighting and a two-way radio, and they spend long stretches at low speed off-road, so a higher-output unit restores charge faster between camps. The RX330 and RX350 crossovers are covered too.
Confirm your year and engine in the vehicle finder, since Lexus nameplates are split by engine and generation. A 170 Amp Lexus high output alternator fits a sedan with a single amplifier. 240 Amp suits a component system or a crossover with extra accessories. 320 Amp covers multi-amp audio and SUVs with heavy camping loads, and 370 Amp is listed for select V8 models with larger demands. Units come in natural or black finishes with standard housings.
Mechman high output alternators should be paired with a wiring kit rated for the new output, a fresh battery from our battery selection and any parts from harnesses and regulators. Lexus units sit alongside Toyota on all Toyota and Lexus alternators, and every make is on our alternators page.
