3 4 Race series converters are built, tested, and proven to support up to 650 HP 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 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. 3 4 Race series converters are offered in several different stall speeds for GM
