The No-Compromise Converter for High Performance Street, Towing or Racing Applications! In high performance, high-load situations, the torque converter bears the brunt of the engine's force. Inferior torque converter designs can slip excessively, causing the oil to foam and boil, and the front cover to balloon, even rupture. But BD's ProForce torque converter was specifically designed to handle the kind of punishment you dish out. BD torque converters feature exclusive performance cast aluminum stators that improve efficiency and durability for better response in stock to higher horsepower applications. Each BD-engineered torque converter features a stamp-forged steel front cover, furnace-brazed fins, and up to triple the amount of lock-up clutch material.
