Hays Twister 3/4 Race performance torque converters are designed to be the perfect solution for your street/strip machine. Hays designed the Twister torque converters to be one step short of being a "Full Race" converter giving you the perfect combination of performance and affordability. Every torque converter is hand built, inspected and tested to ensure they meet the top of the line quality you expect. To ensure consistency and improve performance each converter is built for one transmission with one bolt pattern, meaning a lighter converter to maximize performance.
