About Diesel Freaks
Diesel Freak LLC is a group of talented mechanics that live, eat, sleep, and breath diesel engines. Diesel Freak the name came from a customer that always called us by this because of our nature and it has stuck.
We started development of our power harnesses back in 1996, After being frustrated with the electronic engines and the capability to adjust certain parameters. With the older mechanical fuel delivery systems we could control anything we wanted and the electronic engines limited that control. We figured out that with the use of wiring harnesses we could get some of that control back that we had lost. So after hours of testing and tuning we developed the Diesel Freak power harnesses.
Sales of these harnesses started to sky rocket and the results have been fantastic. Gains in power have been from 30 hp to 100 hp. And the torque numbers are bigger; gains from 100 ft. lbs. to 250 ft. lbs. have been achieved. Not only has horsepower and torque been increased but fuel mileage has increased as well, gains have been from .2 mpg as high as 2 full mpg. These harnesses are safe to your engine also, they can't make your engine go any further than what the factory parameter maximums are set. They simply make your engine perform closer to these maximums.
We also have had a hard time great trucking related T shirts so we decided to make some of own. Diesel Freak apparel and merchandise has been sold all over the world and has been worn by some of the actors on Ice Road Truckers and other TV programs making it's popularity in the trucking industry soar. We have developed this website to make it easier for you to buy our products.
