FTI Performance SST Series custom-order torque converters are available for use with a variety of transmissions, including Powerglide, THM350, and THM400. The 9 in. units are used by top drag racers. A torque converter is what transmits torque from the engine to a rotating driven load. It's a type of fluid coupling which allows the engine to spin somewhat independently of the transmission. SST Series torque converters are available with a 0-blade stator for a turbo spline, or the looser 6T stator model.

Hays Twister Full Race Torque Converters feature a custom-designed anti-balloon plate to stop any converter ballooning and swelling in racing situations. These torque converters are designed for use with a trans-brake and great for power adders such as nitrous, superchargers, and turbos. They're available with various RPM stall speed offerings to accommodate any mixture of modifications—including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss. Additional product features: * All Full Race Series converters are built, tested, and proven to support up to 1,000 hp * Designed to handle the extreme shock and abuse of trans-brakes, nitrous oxide, superchargers, and turbochargers * State-of-the-art spray welding process is used in select areas. Spray welding provides clean, strong, and consistent fusion while also increasing strength through hardening from higher process temperature * Each converter is hand-built and inspected in every step of assembly to ensure top-of-the-line quality * All Hays torque converters are internally welded, compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency * Heavy-duty Torrington bearings are used for greater strength and durability * Stators are chosen with high-flow vents and channels to promote cooling in heat-producing higher horsepower applications * Increased horsepower and acceleration due to a weight-saving, one-application design. Almost all Hays converters are built for one application to reduce weight, compared to a multi-bolt pattern converter * Full Race Series torque converters are offered in several different stall speeds for popular automatic transmissions.

TCI Competition torque converters are proven race winners and an excellent choice for stock and Super Stock cars. They work well with both big and small blocks, producing power between 4,500 and 7,000 rpm. You'll maintain engine rpm between shifts with their efficient design, and gain improved reliability with an oversize caged bearing supporting a new stator. ETs are more consistent and reaction times faster as a result of a stronger housing, which resists flexing and ballooning.
