Hays TWISTER 3/4 Race Torque Converter, 2800-3200 RPM (1992- GM 4L60-E & 4L65-E)

9.6" diameter torque converter with lock-up 30 spline input, 300mm (LS engine only), 11-1/8" bolt pattern, 2800-3200 RPM stall

• 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

Warning: The 3/4 RACE series converters are NOT designed to be used with Nitrous Oxide or Trans-Brakes

Note: HAYS recommends an external transmission cooler for all Twister 3/4 Race Converters (A minimum size of 18,000 GVW or 15,000 BTU Rating.)

Note: Stall ranges will vary depending on engine set-up, weight of vehicle, and gear ratio
