We are producing the pit buggy that the Factory Team has used for years. This buggy comes with no flat, heavy duty wheels and tires. We also have added a 2" deep tray for air gauges and misc. tools. The steering can be rotated 180 deg. for great maneuverability. Plus this buggy is extremely light; it can be picked-up by one person. The other great features is awesome stability, durability, and this buggy was designed to a hieght that allows one person to take the car on or off the buggy if necessary. Cars can be ratcheted down in the trailer while still on the buggy, and the tires are fantastic through gravel. Never have a flat tire again! Units come unpowdered.
