The Circle D Specialties HP Series 10R80 Torque Converter, part number 46-07-05, is a high-performance upgrade designed for 2018+ Ford Mustang GT and F150 models with the 10R80 transmission. This converter is based on the original factory unit but enhanced with a CNC-machined billet stator and custom impeller modifications. Constructed with precision, this torque converter features a CFD-designed 5th-axis CNC-machined billet stator, ensuring optimal fluid dynamics. The entire unit is hand TIG welded for maximum durability, and it includes custom internal clearances and Torrington style bearings for smooth operation and longevity. Impeller fin recalibration further enhances performance. This converter is available in multiple options to accommodate various engine configurations, power-adders (Naturally Aspirated, PD Supercharger, Centrifugal Supercharger, Single or Twin Turbo), and specific vehicle setups while aiming to retain pleasant street driving characteristics. The converter diameter is 258mm, and multiple stall speed options are available, ranging from 2800-3000 RPM up to 4200-4400 RPM. Please note that this product is built to order and has an estimated build time of 4-6 weeks. Proper stall speed and vehicle configuration are critical for optimal performance and drivability. It is recommended to contact Circle D Specialties to confirm the correct setup for your specific application.
