FTI Ford 4R100/E4OD BA Series Billet Lock-Up Diesel Converter - 4 Stud - Triple Clutch - Low Stall

FTI Performance is known for building robust drivetrain components, and this BA Series Billet Lock-Up Torque Converter is a prime example of their work for Ford diesel trucks. This converter is specifically designed for the 4R100 and E4OD transmissions, offering a significant upgrade over stock, especially for those running modified diesel engines. It features a low stall speed, meaning it engages power more quickly from a standstill, which is beneficial for towing or when you need immediate response off the line. The triple-clutch design provides a larger surface area for engagement, helping to handle increased torque loads and improve durability under demanding conditions.

The construction of this converter is all billet, meaning the entire case is machined from a solid block of aluminum. This makes it incredibly strong and resistant to the flex and distortion that can occur with stock, multi-piece welded converters, especially when dealing with the high torque output of diesel engines. The 4-stud design further reinforces the lock-up mechanism, ensuring a solid connection when the converter is locked. This is a critical component for anyone looking to improve their truck's performance and reliability, particularly if you've upgraded your engine or plan to tow heavy loads regularly. The low stall speed is a key characteristic, making it a good match for applications where you want the engine to feel more directly connected to the drivetrain sooner.

When installing a high-performance torque converter like this, it's important to ensure your transmission fluid is fresh and that the transmission itself is in good working order. Because this is a specialized part for diesel applications, it's built to withstand the unique demands of those powertrains. While this converter is not CARB approved and cannot be shipped to California, it represents a solid option for diesel truck owners outside of that state looking for improved drivetrain strength and performance.
