Show original supplier description
The Circle D 07N-09-07-2A is a 278mm HP Series torque converter engineered for the 6L80E transmission, offering a 3000-3200 RPM stall speed and a billet cover. This converter is designed to handle up to 750 horsepower, making it suitable for daily-driven performance vehicles, LS swaps, restomods, and various other applications. Key features include a billet cover for enhanced durability, hand TIG welding for maximum strength, a woven carbon lockup clutch lining for improved performance and longevity, heavy-duty Torrington bearings, an exclusive CDS bearing retainer, and an anti-balloon plate to minimize ballooning under high load. This torque converter is a popular choice for applications such as 2010-2015 5th Gen Camaro SS, Pontiac G8, LS truck applications, and LS swaps. It is built to order with a 4-6 week build time. Important Note: This torque converter does NOT fit C6 transmissions. Proper stall speed selection is critical for performance and drivability; it is recommended to contact the manufacturer to confirm compatibility with your specific vehicle and combination.
