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.
