Tuff Stuff - MAX AMP Alternators
These MAX AMP alternators provide nearly 50% more amperage than the stock alternator, yet they retain the OE form factor for a direct fit. Add-on electronics like high power stereos can easily overwhelm the OE alternator. Our new MAX AMP alternators can handle nearly any load with output up to 210 amps at idle!
The huge copper windings, giant diodes and premium quality ball bearings assure maximum output and extreme dependability. They incorporate twin internal cooling fans that prevents overheating. In addition to Chrome Plated, these MAX AMP alternators are also available in either Polished Aluminum, Stealth Black or Factory Cast PLUS+ finishes and include a 6-groove clutched pulley. Available in both 175 amp & 250-amp versions.
