Cummins 300 big cam custom Peterbilt rat rod SEMI truck

When it comes to rat rod rides, you see these machines sculpted in every way, shape, and form. The variety of build is kind of the point of creating a rat rod in the first place.

Even though each one is unique in and of itself, many of them sport similar engines from the commonly used LS transplant to small block Fords and everything in between.

This time, however, the hobby of rat rod building takes on an entirely new face with Cummins power is found under the hood and that isn’t where the cool factor stops.

When we continue to the chassis, we see that this rat rod is built off of the likes of a Peterbilt big rig, making the chopped up creation even more unique.

Check out the loud and proud Peterbilt rat in the video below and tell us what you think of this wild child that brings many custom touches to the table.
