With each passing year, TTC rigs have only seemed to grow larger. As proportions increase, so do the demands on drivetrain components. We have often wondered if someday we will see nothing but Rockwell axles under our top ten vote-getters at TTC. In '09, five out of ten competitor rigs had grown past the traditional Dana/1-ton running gear to the superior Rockwell axle sets. Shown here is Brett Jerome's custom Jeep buggy on 54-inch Baja Claw TTC tires as he negotiated our Mini-Rubicon boulder field.
