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

If you're building a high-performance diesel truck with a Ford 4R100 or E4OD transmission, you know that the stock torque converter can be a weak point. This FTI Extreme Series Billet Lock-Up Converter is built to handle the extra power and torque you're putting down, especially in demanding diesel applications. It's designed to be a direct replacement for your factory unit, but with significantly improved strength and performance characteristics.

This converter features a billet aluminum cover for increased strength and rigidity, which helps prevent flex under heavy load. The triple-clutch design offers more surface area for engagement, leading to smoother lock-up and better heat dissipation compared to dual-clutch units. The low stall speed is ideal for diesel engines, allowing them to build boost more effectively before the converter fully engages, which translates to better off-the-line performance and towing capability. FTI uses high-quality internal components and precise balancing to ensure reliability and longevity, even when paired with significant engine modifications.

When installing this converter, it's important to ensure your transmission fluid is fresh and that you follow the manufacturer's guidelines for filling the converter before installation. This unit is not CARB approved and cannot be shipped to California. It's a solid choice for anyone looking to upgrade their diesel's drivetrain to match increased horsepower and torque.
