I have my modified Blazer thanks to my brother, a mechanical genius in his own right. He does the mud racing up in East Texas and has built a couple of mud trucks in stages of madness. This is his last creation, the frame built from scratch and over a couple of months. It has 63" tires on it now, don't have any of those new pics but the military tires you see on it are 40" and look pretty small. With 2 1/2 ton axles and full hydrallic steering it will blow through the pits in about 7 seconds.
