GM SNS LOCK UP TORQUE CON

The TCI Automotive 242900 Saturday Night Special Torque Converter is designed for GM 4L80E transmissions from 1991-2006. It's engineered for performance enthusiasts looking for a significant increase in performance on the street or at the strip, offering a 400-500 RPM increase in stall over stock. This converter provides quicker acceleration and improved low-end power, making your vehicle run more smoothly. It's fully streetable with no modifications required. Key features include furnace-brazed fins for reinforcement, heat-treated sprag races, bearings to increase thrust capacity and reduce drag, turbine spline reinforcement welds, and a heat-treated steel hub. Each unit undergoes a "Triple Tested" production process, including impeller-to-front cover welding verification, leak testing, and computer balancing to reduce drivetrain vibrations.
