Alternators for Toyota & Lexus

Toyota and Lexus vehicles stay on the road for years, and many pick up electrical load along the way: a Tundra with a light bar and fridge, a Land Cruiser set up for overlanding, a Camry with subwoofers in the trunk. This page brings together every Toyota high output alternator we carry for Toyota, Lexus and Scion. Use the vehicle finder or a model page to see units that fit.

Sedans, crossovers, trucks and overland rigs

The Toyota range covers daily drivers and serious off-roaders alike. The Toyota Camry alternator page spans 1994-2017 with four- and six-cylinder engines, and Highlander high output alternators and RAV4 alternators cover the family crossover side. Truck owners can go to Toyota Tundra alternators for 2000-2021 trucks, including the 5.7L. Overland builders will find Land Cruiser alternator upgrades and 4Runner alternators. Lexus coverage includes the SC300, GS300, IS, ES, RX, GX470 and LX models, and the Toyota Supra, Solara, Matrix, Sequoia, Tacoma and Scion models are in the vehicle finder too.

How to pick the right unit

Every Toyota high output alternator here is fitted by year and engine, so use the vehicle finder or your model page first. A 2.4L Camry and a 3.5L Camry take different alternators, and the same is true across most Toyota and Lexus lines. The year/make/model selector at the top of each model page then shows which series fits which years and engines.

Output runs from 170 Amp to 370 Amp. Most models offer 240 and 320 Amp. The SC300 and Supra list 170 and 240 Amp, and the Land Cruiser adds 250 and 370 Amp options. 240 Amp handles one amplifier or added lighting well. 320 Amp suits multi-amp audio or a fridge and inverter. 370 Amp on the Land Cruiser is for heavy overland loads such as a winch, lighting and a dual-battery setup.

Housing and finish

Most Toyota and Lexus units here use a standard housing in a Natural finish. If a billet version is listed for your model, the housing filter will show it. The SC300 and Supra also offer a Black finish.

Upgrades that work with it

Mechman high output alternators need wiring sized for the current. Add Big 3 and amp wiring kits, and consider a deeper battery from our battery collection. Plug adapters and regulators are in harnesses and regulators. To compare other makes, browse all alternators.
