- All Full Race series converters are built, tested, and proven to support up to 1,000 horsepower
- 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
- Industry leading Tech Support Team is available to provide assistance with stall speed selection
- Features a custom anti-balloon plate designed to stop potential torque converter ballooning
- 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
