190 Amps, 140 at Idle

The 190 Amp Version is the ultimate upgrade for the Diesel Truck. It is the perfect choice for either a reliable stock upgrade and it will handle a high powered stereo, hho generator, winch, trailer lighting,inverter or any other current drawing accessory you want to install on your truck with no problem. The original 6G Ford diesel alternator on these trucks was only rated at 110 amps and only makes 60 amps at idle! This alternator will make 140 amps at idle, HOT! With this alternator you are gaining an extra 80 amps of output, AT IDLE!

These alternators are NOT just overwound, stock Ford high output alternators with low or zero output at idle like the competition sells that just dont work, The TAD-190 OEM series alternator is a specially designed Large Case alternator that weighs an incredible 8lbs more than the stock Ford 6G alternator, and is capable ofproducing the large amounts of output that the Factory Ford alternators are just not capable of! Dont be fooled by othermanufacturers claims of their so-called Ford high output alternators, their supposed "high output" alternators are no match for our "stock"190 Amp TAD-190 alternator. The TAD-190 OEM is the overall best value alternator we make for the Ford Powerstroke diesel, and it produces over 2/3 of its rated output at idle! Simply put, there isn't another alternator like this that will deliver this kind of output at ALL speeds! All of our OEM series alternators have our exclusive USA made and special wound, heavy duty stator windings that gives our alternators their incredible low speed output and also lets the alternator run much cooler than other stator windings and deliver unmatched performance!

This alternator is our overall best value alternator for Powerstroke engines! Give you high performance at idle, 140 Amps, which means that your vehicle will always have the power it needs. This alternator is built from 100% BRAND-NEW USA made parts!This alternator is a Direct Bolt on OEM fit with no modifications necessary for easy installation! Comes standard with our custom pulley for MAXIMUM output at idle! Comes with heavy duty rectifiers that feature six, 75 amp diodes in MASSIVE aluminum heat sinks for optimal current transfer and optimum heat dissipation under high heat, high output conditions for better outputs and longer life.

Backed up with a worry free 2 year warranty!!

AmAzInG Customer Service!!! May 12, 2015
Reviewer: Rachel Faulkner from Patterson, CA United States  
I knew I wanted to buy a DC Power alternator, but I honestly couldn't find anyone to sell me one. No return phone calls, rude customer serivce, out of stock, etc.! I was so frustrated. Then I called Holly at Nations and she sat on the phone with me, answered all of my questions and got me the product I needed. I know if there are any issues nations will be there to back their product and thats what I was looking for! Thank you for your great customer service!

In my 2003 6.0 Excursion September 13, 2014
Reviewer: Anonymous Person from CO United States  
Fast shipping and works like a champ.  I should have installed one if these long ago!  Great replacement for the stock 110amp alternator that the brilliant Ford engineers put in their trucks.
