Those drivers who insist on conducting three or four stall tests in the pits and conducting three or four dry burnouts prior to staging at wide-open throttle should use the heavier planetary. If you're using more than 500 hp, you're going to want to equip your performance vehicle with ATI's high-impact gear sets. These precision-balanced carriers are manufactured from 9310 material for added strength and durability and are designed to provide heavy-duty output.
