Trophy Trucks are the fastest class of off-road racing vehicles designed and built to resemble modern pickup trucks. Although any truck that meets the safety standards can race the trophy truck class, they, for the most part, feature long travel suspensions and high power engines. They are intended for desert racing, and are not street legal.
They are most often 2-wheel drive, they do have a class that is 4-wheel drive, and most feature a 4130 chromoly tube-frame chassis covered by a fiberglass or other composite body. Engines are required to be naturally aspirated, and are typically V8s generating in excess of 700-850 hp. Suspension travel can exceed 30 inches (760 mm) depending on chassis design. Most Trophy trucks use independent A-arm suspensions up front. In the rear, most trucks use a 3 or 4-link setup with a solid axle, while some use various types of independent suspension. Suspension and damping duties are handled by 1 or 2 shock absorbers per wheel; usually consisting of one coil-over and one by-pass shock.
The roll cage is the bars you see running inside of the vehicle. The roll cage is made of different types of steel tubing. There is mild steel and DOM (Drawn Over Mandrel). Mild steel is really easy to bend, with it being easy to bend it won’t break. DOM steel is the steel that is mainly used for roll cages, it is a lot harder than mild steel and doesn’t bend as easy. With DOM steel being harder this is why it mainly used. 
The typical cost of one of these trucks is $300-$500,000, this does not include; race entry fee, tool cost, parts cost, and fuel. A Craftsman tool set is $450 worth and this is a good place to start for tools. It’s $30,000 to enter each race and a $100,000 pay if you win, and there is 8 total races across country. Cameron Steele, a veteran in racing, spent $20,000 in gas for only a two day event. The biggest event is the series is the Baja 1000 down in Mexico. In 2013, the time that won was 20:00:59 by B.J. Baldwin in his Chevrolet Silverado.
