Product Details

The Tuff Stuff Performance 7068K is a high-output 140-amp alternator designed for street rods, muscle cars, and performance applications requiring reliable charging power. This one-wire alternator features a smooth back housing for a clean, streamlined appearance and simple installation that eliminates the need for an external voltage regulator or additional wiring harnesses.

Key Features:

  • 140-amp output provides ample charging capacity for high-demand electrical systems
  • One-wire design simplifies installation with self-exciting internal voltage regulator
  • Smooth back housing offers a clean, polished look without external fans or brackets
  • V-groove pulley included for standard belt applications
  • Factory Cast PLUS+ construction ensures durability and heat dissipation
  • Internal regulator eliminates need for external voltage regulation
  • Ideal for GM and compatible applications with proper mounting brackets

This alternator is engineered for performance enthusiasts who demand reliable power output with straightforward installation. The one-wire operation means it begins charging automatically once engine RPM reaches the self-excitation threshold, typically around 1,200 RPM. Perfect for street machines, hot rods, and custom builds where clean engine bay aesthetics and dependable charging are priorities.

I was looking for a part for my Mallory distributor at a fair price. I called around to my local speed shops and they all had to order the part, so I went on line. With a little research for the best price here, at Autoplicity. I ordered the part last night and it has shipped 24 hours later. I like that. I have bookmarked Autoplicity so I can use the again. Thanks guys.<br><br>Jim
