12V fummins swap 6.4 fan solution

Here is how I integrated the stock 6.4 fan onto the 12v fan bearing. I had a thread adapter machined to screw into the stock 6.4 fan clutch and then onto the 12V bearing. Running destroked engine mounts this gave me the perfect amount of room to run this fan. I have never been in a truck with colder AC.

Website Updates

I've been working hard on new updates and design for my website. Key focus on design and navigation.

Main landing page: clean, refined, and a new mega-simple menu.

Product pages will gradually gain new info tabs, where any fitment info will go.

"Find your truck" is a Year Make Model search that AI and I built 😂 but all kidding aside, it works well.


all in an effort for less clicks on the end user, and like always, dealers are welcome to text in orders or login to get your discount as well (shown in cart) if any shops are looking for dicounts please reach out to me.
