7" Race Converters
TCI® helped lead the way in the design of the 7" race converter. Developed for use with a small cubic inch engine or very high rpm engine (8500+ rpm) that requires the ultimate high-stall converters. The TCI® 7" race converter delivers higher stall and better top-end lock-up than an 8" converter. Because of the wide variety of engine combinations, tire sizes, gear ratios and weights of different vehicles, we have provided a reference chart to use when ordering your 7"·converter.

8" Race Converters
Our best-selling race torque converter. Suitable for the greatest percentage of drag cars, TCI® 8" converters win races in classes from bracket racing and Super Gas to Sand Dragging and Stock Eliminator. We continually work to refine the dependability and consistency in these converters to give you a better unit. Most of our models now feature a cast steel stator supported by an oversize caged bearing for added reliability. Current models also feature an improved housing design for less flex or ballooning under the stress of racing, resulting in more consistent elapsed times, faster reaction times and better durability.

9"-10"-11" Race Converters
All TCI® race converters incorporate aftermarket high-load sprags, furnace-brazed and reinforced fins, needle bearings and hardened steel pump hubs. All of our 9-inch converters are built to be suitable for a Trans-Brake or ultra-high horsepower application.

PRO-X™ 9" & 10" Race Converters
TCI® offers a complete line of torque converters built exclusively for six-second nitrous engines. All of these converters incorporate hand-fabricated steel stators, oversize bearings, races and anti-balloon plates. They are well-suited for 500-plus cubic inch engines with multiple-stage nitrous or supercharged induction.
