Mechman S Series Alternators

The S series family of alternators offers large case alternator performance in a compact package. Highly efficient, these 6 phase alternators use less horsepower per Kilowatt than conventional 3 phase alternators. 12 press fit diodes, twin rectifier plates, and highly efficient twin internal cooling fans make them durable in any application. Smaller, lighter rotors and reduced rotating resistance make them an excellent choice for high RPM or racing applications. Like their big brothers in the Elite series, the S series have hairpin stators and high pole count rotors that create much less Electromagnetic noise than conventional 3 phase alternators.

  • 240 amp alternator
  • For use with select 1992-2003 Dodge/Jeep vehicles

devin l on Feb 24, 2015
would this fit my 2002 toyota 4runner sr5? 3.4 L engine. i know it wont be a direct direct fit.. but with slight modification it should correct? because about 2 weeks ago i installed a CS-144 GM alternator in my 4Runner and it fit in flawless.. all i had to do was adjust the bottom mounting bracket just a little. and add a few washers to the bolt and it looked great.. i ended up returning the alternator because it was a cheap ebay BRN alternator and i read alot of bad reviews after i bought it.. but thats returned and i want to get a real good alternator because im planning on running around 8,000-10,000 watts RMS all together sound system.. and i cant do a dual alternator and i cant do anything over a 270amp alternator because of my pully system.. so im very limited

Besides getting a bracket to make this fit my motor would it work on a 1200/1.2i engine size?
