The BD Diesel 6R140 ProForce 4D Torque Converter is engineered for demanding applications involving heavily modified 6.7L PowerStroke Diesel engines. Designed to deliver exceptional torque capacity, this converter features four clutch surfaces that significantly improve heat dissipation and clamping force, supporting up to 900+ horsepower. The CNC-machined forged billet cover ensures optimal strength and prevents warping or imbalance during high-stress operation, allowing for increased clutch engagement without compromising durability. It includes a custom piston, bearing hub, release springs, and backing plate that retain the OEM captured clutch design, offering smooth drivability and reliable performance in heavy-duty towing and performance scenarios.
