The chassis is made with 4mm thick square steel tubing and has a galvanized coating to protect against nature's elements. The dump box is also galvanized and is mounted to it's own powder coated reinforcement structure for added rigidity. The complete chassis system connects to a heavy duty tandem axle system featuring 4-bolt hub bearings where the four 22x11-10 offroad ATV tires are mounted. The tandem axle utilizes one pivoting pin that comes standard with a grease-able zerk fitting.
