Rock crawling is very much about ground clearance, but even more so is the way that weight and gravity can play out when your rig is on the rocks. There is no mistaking this. This simple matter of science shows up time and time again every time a rock-buggy rolls, flips, slides or slips ass-backwards. First, take into consideration the weight of the entire vehicle. Some say that super-light-weight is the way to go, while others may feel that a more hefty vehicle will get better traction and help with stability. Just look at the pro's. Walker Evans's latest crawler runs a 2.2L EcoTech motor in front of a 2-speed powerglide transmission. The engine and the tranny together likely weigh in at less than 350lbs! Others will gladly use a cast-iron V-8 and TH400 transmission, that likely weigh damn near 700lbs. What is the truth? Should a rock-crawler be as light as possible, or is extra weight not necessarily a bad thing???
