Quadralock Torque Converter

The SunCoast 6R140 2,300 RPM Billet Quadralock Torque Converter (6R140-3) represents a significant advancement in torque converter technology for the 2011-2019 Ford 6.7L Powerstroke. Its innovative captured clutch design revolutionizes lock-up strategies by eliminating the need for fluid exhaustion from the apply piston's backside, resulting in much quicker engagement. SunCoast offers a variety of custom stator options, allowing for tailored performance whether you need an improved stock replacement or a setup for serious competition like sled pulling. This specific model, the 6R140-3, is built upon the foundation of the 6R140-2 but incorporates a unique custom stator. This modification provides an additional 200-300 RPM of stall speed, making it particularly beneficial for trucks equipped with slightly larger turbochargers that still handle heavy towing duties. The result is faster turbo spooling compared to factory stall speeds, enhancing responsiveness for both street driving and track use. Constructed with durability and performance in mind, this torque converter boasts features such as furnaced brazed fins, Anti Drag Captured Clutch Technology (ADCCT), a 4140 HTSR billet steel clutch retain ring, a CNC-machined billet forged one-piece cover, and a Torrington Thrust bearing design. It also incorporates an increased clutch count, Quadralock captured clutch technology, a larger apply piston for enhanced clamping force (over 1,000 PSI), an upgraded custom sprag, and a billet stator for superior efficiency.
