Theres really nothing less complicated than mixing water and dirt. The complication comes in the task of compiling the right drivetrain components and gargantuan amounts of rubber. Bigger motors mean more cooling. More torque equals beefed-up axleshafts, U-joints, and knuckles. This, of course, is why were bringing you big, bigger, and biggest buildups for mud rigs. The rigs were selected based not only on their capability but also on their MA (mud aptitude). Since all of the trucks have major disguises, dont be surprised at what youll find underneath their skin.
