258mm Pro Series 6R80 Torque Converter

The Circle D Specialties 258mm Pro Series 6R80 torque converter is a high-performance component designed to handle demanding applications, particularly those involving positive displacement blowers or turbochargers. Constructed with durability and performance in mind, this converter boasts 100 square inches of clutch lining, ensuring robust lock-up during Wide Open Throttle (WOT) conditions. Its construction involves furnace brazing and hand TIG welding, enhancing its bonding and heat dissipation capabilities. Internal components include Torrington bearings for smooth operation and long-term reliability, a billet front cover and lock-up apply piston for increased strength, and a flanged impeller hub to resist flexing under high torque loads. Each unit is meticulously hand-assembled to precise tolerances. This Pro Series converter is available in a 258mm diameter, which is ideal for heavier cars, smaller trucks, and builds with significant power increases or those intended for performance street use. Three diameters are offered for the 6R80 Pro Series Multi Disk lineup: 245mm for lighter vehicles and naturally aspirated setups, 258mm as detailed here, and 265mm for extreme horsepower or large, heavy trucks. Note that this is a custom-manufactured product with a build time of 4-6 weeks. Proper stall speed selection and vehicle configuration are critical for optimal performance; contacting Circle D Specialties for confirmation of the correct setup for your specific build is recommended.
