THE WAIT IS OVER!!!  A true 300+ amp alternator for the SOHC Ford Modular Engine family can now be utilized in a real-world application. We have 100% solved the poor belt wrap that has held this platform back for years. 

Since the early 2000's these V8 & V10 SOHC engines have had some of the worst belt wrap for an upgraded high output alternator.  With the belt only touching appx. 1.2" of effective pulley surface area, this left little to no grip needed to properly operate a high output alternator over 250 amps. This is having been the reason we are one of if not the only manufacturer to limit our selection to just a 250-amp version for so long.  We either do it right or not at all. 

There are many different fitments and brackets throughout the years on the engines, but we have chosen to include all the necessary brackets, hardware and pertinent items needed to mount this alternator CORRECTLY.  Correctly in this case means with a properly designed upper bracket area to eliminate alternator flex and belt deflection. You may or may not need all hardware/brackets included to install on your application.  We chose to provide all that would be needed just in case of mid-year changes or fitments that has been discovered. (see all included items in picture gallery)

This is THE ONLY alternator of its kind like this in the world for this platform and proves that we look to innovate and not duplicate like our competition.  Please be sure to check out our ultra detailed instructions online for this P# to better familiarize yourself with why this is hands down the best option for the SOHC engines. 

Installation notes:

Uses GM 4pin style regulator with our H105 adapter harness for plug and play connection. Can also be ran as single wire turn on and use voltage boost harnesses.

Must use 0-gauge power and ground wires directly to battery for best install performance results.

In some/most applications you will reuse and/or relocate your OEM idler pulley(s) to maximize grip. See instructions for belt size recommendations. 

Optional idler pulley add-ons for even more extreme grip!  

Please refer to any and all pictures in the included instructions. Fitment is tight in some applications; however, all testing has shown no signs of wear or fail due to fitment location restrictions.
