TCI 11" Breakaway Torque Converter 1965-81 GM TH350/TH375 Small Bolt Pattern (Except Lock-up)

TCI Breakaway Torque Converters are designed for use in moderately modified street machines, weekend racers, and as daily driving use. Breakaway Torque Converters provide between 2400 to 2600 RPM flash stall without negatively affecting part-throttle driving. TCI has engineered these Breakaway Torque Converters to be efficient at highway cruising speeds and to launch hard at wide-open throttle. Each unit is built to meet or exceed OE specification and triple tested during assembly. Once all the prep work on the component parts has been completed, the impeller is welded to the front cover. Immediately following this process, a pair of dial indicators are employed on a rotating table to verify that the impeller body and pump drive hub remain true. Each unit is then pressurized and subjected to a leak test to confirm the integrity of all the weld seams. Lastly, each unit is computer balanced to reduce annoying and potentially damaging drivetrain vibrations that would occur from an unbalanced torque converter. That's Triple Tested so you can be confident you're getting a torque converter that's ready to roll
