The BD 6R140 ProForce 4D Torque Converter is designed for hard-working and modified 6.7L PowerStroke Diesels. This torque converter is equipped with 4 clutch surfaces designed to handle heavy towing loads and is intended for up to 900+ horsepower. Our in-house CNC machined forged cover is designed to prevent warping and improper balance while facilitating the increased clutch count without sacrificing strength. In addition to a new cover, BD has designed a custom piston, bearing hub, release springs and backing plate to retain the OEM captured clutch design which delivers the same great drivability 6R140 owners are accustomed to.
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, billet steel piston, hardened piston seal bore, improved friction lining and steel Torrington needle bearings which replace plastic thrust washers. Tested to 1,000 lbft crank torque!
