Rock Buggy's are usually made of round tubing like D.O.M. or Welded Seam tubing and have 4 link suspensions. They use Coil-over shocks or Air Shocks to support the weight of the vehicle. These Buggy's are very capable off road and sometimes even have steering in the front and rear to help navigate the terrain. Some are built with 2 seats and some 4 seats. What these vehicles can drive over is no joke. If you ever get a chance to go for a ride don't pass it up, you wont be sorry.
