Design, made, and assembled in the USA as it should be

This product works as advertised bench tested the same as the ticket. Great product! I would recommend to anybody. Quick note, 2014 Chevy Silverado. The battery light did come on after the installation of the module 103 however, it did go away after a short acclimation period.

Best of the best out there

Crazy good voltage easy install got the specified smaller belt for my vehicle fit with no issues cold start getting about 15.2 volts once everything is charged up and warm sitting at about 14.8v puts out real good power at idle 600-650rpm drops to around 14.3v with 2 agm batteries and a 4k amplifier and a 1400w amplifier

Works Great!

Alternator working really well on 2001 chevy Tahoe little to no voltage drop when Bass hits would definitely buy another..5.3 vortec engine original belt fit just fine Didn't need a shorter one.

Corriendo un taramps Smart 3k y 2 skar 1000.4ab

Asta ahora todo va bien, si alcanzo a percibir un poco las caídas de voltaje pero es algo muy leve, ya que tengo alrededor de 5k w rms corriendo en este alternador y valla que le suda, hay que aclarar que esto sería imposible en alternador de stock, pero como dije: asta ahora todo va bien con el y nada de problemas eléctricos. Antes de todo recuerden hacer big3 en el, recomiendan cable 0 pero yo me fui con 2/0

Powerful

Replace my alternator with this 400 and gave my smart 5k blow my speakers boxes apart, but make sure you replace your vehicle main fuse with bigger amperage

Works flawlessly

This alternator operates beautifully. Comes with DETAILED instructions on how to install it with the proper harness extension and belt length. Keeps my d4s jp63 and my lithium bank very happy. Will purchase again, and will refer my friends.
