BD Diesel 2011-2016 Ford F250/F350/F450/F550 6.7L Proforce 4D Torque Converter

If you're pushing your 6.7L PowerStroke diesel in your Ford F-250, F-350, F-450, or F-550 beyond stock, you need a torque converter that can keep up. This BD Diesel ProForce 4D torque converter is built for those hard-working and modified trucks, especially when you're dealing with heavy towing or significant horsepower increases. It's designed to handle up to 900+ horsepower and has been tested to withstand 1,000 lb-ft of crank torque, giving you confidence when you put the pedal down.

What sets this converter apart is its robust construction and updated design. It features four clutch surfaces, a significant increase from the factory's two, which helps dissipate heat much better under load. This improved heat management is crucial for preventing premature wear and ensuring consistent performance. The converter also boasts a 23% larger piston area, which means more clamping force on the clutches for better engagement. BD Diesel uses a CNC-machined forged cover to prevent warping and maintain balance, even with the added clutch count. They've also updated the piston, bearing hub, and backing plate to keep the OEM captured clutch design, so you still get that familiar, smooth drivability you expect from your 6R140 transmission.

Inside, you'll find performance cast aluminum stators for improved efficiency and durability, along with a stamp-forged steel front cover, furnace-brazed fins, a billet steel piston, and hardened piston seal bores. Steel Torrington needle bearings replace plastic thrust washers for added longevity. This converter comes with hardware and is designed as a direct replacement, though it's important to note it is not CARB approved and cannot ship to California. If you're looking to upgrade your drivetrain for more power and towing capability, this is a solid option.
