TCI Breakaway Torque Converters These TCI Breakaway torque converters will give you about 1,000 more rpm stall speed than stock, so you'll launch and accelerate faster. TCI remanufactures them to last with furnace-brazed fins, needle bearings, and a flame-hardened hub--the same qualities that they gave their street/strip converter.
