2/3 Race Torque Converters

Full Race Torque Converters

Designed specifically for blown, nitrous, and turbocharged trans-brake applications and strong enough to withstand the punishment of 1000-horsepower engines, they're available in four different stall-speed ranges: 2400-2800, 2800-3200, 3200-3600, and 3600-4200. They're internally welded (not brazed) for longer life and greater consistency and, in select areas, spray-welded. Heavy-duty Torrington bearings and carefully selected stators with high-flow vents and channels promote cooling, a custom-designed anti-balloon plate prevents converter swelling, and each one is inspected during every step of assembly and hand-built.
  

Hays Twister 3/4 Race Performance Torque Converters

Ideal for street/strip applications. Multiple stall speeds are available to accommodate virtually any combination of engine modifications, including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, and lower gear ratios. Built, tested, and track-proven to support up to 650 horsepower, each Twister torque converter is hand-built and inspected during to ensure top quality. They are offered for GM, Ford, and Chrysler and available in various stall speeds to suit countless applications. State-of-the-art Spray Welding techniques are used in select areas for clean, strong, and consistent fusion, which also builds strength through hardening from higher process temperatures. Each torque converter is internally welded – not brazed – and heavy-duty Torrington bearings are employed for maximum strength and durability. Stators with high-flow vents and channels promote cooling in heat-producing high-horsepower applications.
