Product Details

The Tuff Stuff Performance 7127K is a high-output 140-amp alternator designed to provide reliable charging performance for high-demand electrical systems. This versatile alternator features both OEM-style and one-wire operation capability, allowing for simplified installation in custom applications or direct replacement in factory configurations.

Key Features:

  • 140-amp output for high-performance charging capability
  • Dual wiring options: OEM-style or simplified one-wire operation
  • V-groove pulley for compatibility with standard belt systems
  • Internal voltage regulator for reliable charging control
  • Factory Cast PLUS+ construction for enhanced durability and heat dissipation
  • Premium chrome finish for corrosion resistance and show-quality appearance

This alternator is ideal for street rods, muscle cars, and performance vehicles requiring additional electrical capacity for accessories like high-powered audio systems, electric fans, or auxiliary lighting. The one-wire capability eliminates the need for a factory harness connection, making it perfect for engine swaps and custom builds.

Great customer service. Fast shipping. The products provided are good quality.

Simple. Easy shopping

You seem to have the best price and your pictures help a lot. HOWEVER -- no place did my order say "Mercury Grand Marquis 2003 *Passenger Side* Glass -- and that has me concerned because I have to go by make/model/yr and then picture alone!

I sent my order for some comp cams lifters on Monday 1-16-2012 at around 8:30 and the Item was still shipped on the next day Tuesday. This was awesome. I received my product on 1-19-2012. They have had the fastest turn around time that I have ever delt with. I would highly recommend them for your auto parts needs. They also had the cheapest price I could fine, including the shipping fee.<br>I like the fact that they sent me an e-mail that my item had shipped and gave the shipping number for tracking.

The price is good, easy to fill out the required information, I hope the shipping is fast, paid for 2 days over night, need the part now.

good so far, just ordered a part not available anywhere but autoplicity

Good prices

Your website said that these would not fit my vehicle. However, every other site says they do, including the manufacturer's website.

shipment came very speedy and everything was exactly as expected. All parts were in excellent condition.

Found good price and reasonable shipping. Thanks. H

Thanks full
