Bolts must be 3/8-16 x 3/4 to 1 inch in length and only use Grade 8 quality.

Features and Benefits:

• 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, Ford, and Chrysler transmissions
• Industry leading Tech Support Team is available to provide assistance with stall speed selection
