0-TAMX7113 4WD Chassis Kit - Tamiya 70113 <p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">Capable of negotiating rough terrain, the 4WD Chassis incorporates a four-wheel
shaft-drive system similar to those in full size 4WD vehicles. A hex shaft
transfers power from the center gear box to the outer gear box giving 4WD power.
The large semi-pneumatic tires enhance traction, the roll bar also prevents
damage in rollover incidents.</font></p>
