The blue ones are the lighter weight 106-40's (500lbs). The black ones are 106-47's (1000lbs). I think yellow is for the rear. Per sumo literature the blue ones are for a van (lighter weight) and the black for a box truck. I would say the blacks are better suited for the Axis/Vegas as they are very heavy.
