Our all new line of Mr. Amp Alternators have been improved to combine the best of both worlds, which is higher amperage output in a lighter more compact design! The new High Output Mr. Amp features a shorter housing, making installation much easier compared to the previous version which required modification to the bracket or alternator itself. Output has been increased to a maximum of 240 amps. That’s 50 more amps over our previous generations high ouput model! More accessories can be run at idle as the new gerneration Mr. Amp’s low rpm output has been doubled to produce 130 amps. This means your headlights, A/C, stereo system, ignition system and any other power hungry components will operate at their peak performance level, even if you are running underdrive pulleys! Additional features include an internal fan, heavy duty regulator and high-tech mega fuse with weather proof housing. Mr. Amp Alternators come with six feet of 4 gauge cable, a deep groove chrome plated V-belt pulley and easy to follow instructions. The Mr. Amp alternator is covered by a one year warranty from date of purchase.
