Toyota 03-09 4Runner 4.0L 05-15 Tacoma 4.0L 200-350 amp alternator 14.8v bypassed

These are direct fit 200-350 amp alternators made for 03-09 4 runners and 05-15 Tacomas with the 4.0L engine.

these units are bypassed and includes plug and play adapter for 14.8v so there’s no cutting or modifying your stock wiring. If you’re looking to charge higher or lower than this voltage set point message us and we can help with that, no problem! 

we don’t generally recomend over 275 amps for stock vehicles without increasing the idle rpm for 300+ amp alternators or running an overdrive crank pulley. The 4.0L is a smooth lower idle rpm running engine, due to that 275 amps is seen as the perfect upgrade to drop into a stock vehicle without those changes or less output IE 250 200 amp alternators. The 200 amp doesn’t even require a smaller belt / drive pulley.

make sure to message us with any questions about fitment or wiring. We’re happy to help!
