Tuff Stuff Performance High Output 250 Amp Alternator

The Tuff Stuff Performance High Output 250 Amp Alternator line gives you a high-amperage replacement charging unit. It suits builds with heavy electrical loads, such as winches, auxiliary lighting, and high-power audio. These 12-volt, negative-ground alternators use an external regulator. Output is well above that of a typical factory unit, and they are built to charge at low RPM.

• 250 amp high output to support demanding accessories and upgraded electrical systems
• 12-volt, negative-ground design with an external regulator
• Serpentine (6-groove) pulley included
• Heavy-duty copper-wound coils and premium bearings and diodes for durability
• Spike-resistant diodes help protect against electrical spikes
• Low-RPM charging for strong output at idle and low engine speeds
• Built from 100% new components and tested to meet or exceed OEM specifications
• Hand built in the USA, with a one-year limited warranty
