TCI Maximizer Street Performance Torque Converters

These Maximizer Street Performance torque converters are built with extra reinforcement and thicker mounting surfaces to withstand the additional load and vibration put through the drivetrain by a truck with performance modifications. By providing additional stall, your truck will see better initial takeoff and will not lug the engine when using big tires. Special attention is made to match the converters to the power range of most trucks that do double duty as off-road and daily drivers. Improved rear-wheel horsepower and elapsed times are some of the results.
