There’s 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 we’re 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, don’t be surprised at what you’ll find underneath their skin.
