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.

Yank Performance offers Pro Thruster Series torque converters for a variety of transmission applications, including 4L80-E, 4L85-E, 8L90E, THM200-4R, 4L65-E, 6L80-E, 6L90-E, 4L60-E, 4L70-E, THM700-R4/4L60/MD8, and 8L80E models. The ultimate converter for your car, this series loves big camshafts and RPM. These replacement fluid couplings allow the engine to spin independently of the transmission in automatic vehicles, enabling the engine to keep running when the car is stopped, and facilitating smooth power transfer. The street-strip torque converters are available in a variety of stall speed ratings, bolt circles, input spline quantities, and other options. (Yank does not recommend the use of NOS on this series of converters. The reason for this is the shift extension will get too high. All Pro Thruster Series converters are 9.5 in. billet cover with billet lock up clutch. Rated at 650 RWHP.) * One piece roller burnished hub * New Torrington bearings * Fully furnace-brazed pump and impeller * Hardened splines

Competition Clutch Full Race twin disc clutch kits are rated up to 1,350 hp. They're engineered, designed and developed from years of experience through in-house engineers, enthusiasts, and racers just like you. Competition Clutches are CAD/CAM designed and built featuring proprietary micro finished friction material for smooth easy-driving engagement; precision designed diaphragms; and CNC-machined components. The Power-V drive system allows the floater plates to self-center, evening out the drive forces in the clutch and providing for inherent dynamic balance. Increased surface area of the Power-V lowers stress in the clutch, providing longer life of component parts. This line delivers a superior quality-built assembly designed be a direct bolt-in and just simply work! Competition Clutch did the homework, so you don't have to. Kits are available separately for Honda© B, H, and K Series engine applications.

South Bend Clutch Stage 3 drag race clutch kits are powerfully built with heavily modified vehicles in mind—particularly those built for 1/4 and 1/8 mile tracks. They include a single mass SFI-approved flywheel with each kit, which is typically required for drag racing when the original design is dual mass. The pressure plate is race cover engineered to keep the clutch pedal travel short and quick. South Bend Clutch Stage 3 drag race clutch kits are recommended for drag racing, pulling, and drifting. Order the clutch kit recommended for your specific vehicle and engine size. Features, items, and specs include: * Puck-style disc reduces rotational mass and is assembled with all high-carbon components for maximum strength * Graphite-impregnated ceramic friction material perfectly suited for drag racing (maximum friction co-efficient, rapid heat dissipation, and abrupt engagement characteristics) * Meticulous processing and advanced packaging materials

South Bend Clutch Stage 3 Endurance clutch kits are recommended for single mass flywheel (SMF) when original design is DMF (dual mass) to achieve optimal performance. These kits use the same race-engineered SFI-approved pressure plates as Stage 3 Daily Driver packages. The disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar® friction material is used for its unique friction compounds applied with high-energy levels. This translates to a perfect transition from one gear to the next. Discs are assembled with only performance components and equipped with torsion springs functioning as a damper between engine and gearbox. These Stage 3 Endurance clutch kits are recommended for applications such as rally, endurance race, club sport, autocross, performance street and daily driving. Order the kit you need.
