The AD2 also benefits from revised materials and molded parts for greater strength and durability necessary for today's high-powered nitro off road racing trucks. Special attention was given to produce much stronger shock towers, rear pivot, suspension arms, and battery box. In short, the new AD2 has better traction, stability and rough track handling than you ever thought possible. The unmatched combination of the improved durability, easy adjustment and power handling performance makes it easier to drive"
hope that helps...
