Mechman high output alternators · Authorized dealer
Plenty of RX350 owners use theirs as the weekend vehicle: bikes on a hitch rack, a small trailer, camping gear and a cargo area full of charging devices. A Lexus RX350 high output alternator gives the 3.5L V6 more charging capacity for those loads. Two Mechman units, 320 Amp and 240 Amp, are listed for 2007-2015 models.
An RX350 that tows a small utility trailer or carries a hitch-mounted cargo box often picks up extra lighting, a power outlet in the cargo area and a portable fridge for weekend trips. Add an inverter to run a camp kettle or charge e-bike batteries, and the electrical draw climbs fast. A Lexus RX350 high output alternator keeps the battery topped up while those devices run, even in slow traffic on the way out of town.
The 240 Amp unit handles trailer lighting, chargers and a fridge. The 320 Amp unit adds room for an inverter, an audio upgrade or auxiliary lights. Both Mechman high output alternators cover the 2007-2015 RX350 with the 3.5L V6. Confirm your year and engine in the vehicle finder above the products before ordering.
The same 3.5L alternator series fits other Toyota and Lexus models, including the Toyota Sienna and the Lexus ES350. If you are wiring an inverter or fridge, our amp wiring kits include the heavier cable those circuits need. See every Lexus fitment on the Lexus alternators page.
