Hays Performance Drivetrain is proud to announce the addition of Twister 3/4 Race Performance Torque Converters. Torque converters are a perfect addition to our line of performance Flex-plates, Clutches, and Flywheels. The 3/4 Race converter is the first series we are bringing to market. This series of converters is intended for street/strip combinations, with various stall offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss. |
