Key Features
Hays Performance Drivetrain is proud to announce the addition of Twister 3/4 Race Performance Torque Converters. Torque converters are a perfect addition to our line of performance Flex-plates, Clutches, and Flywheels. The 3/4 Race converter is the first series we are bringing to market. This series of converters is intended for street/strip combinations, with various stall offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss. | The name "3/4 Race Converters" perfectly describes a converter suited for an application just shy of Full Race, which is a series we will offer in the near future. | Hays 3/4 Race Converters! | Good names never go away, and neither should good terms!
9.6" diameter torque converter with lock-up 30 spline input, 10-3/4" bolt pattern (non LS), 3200-3600 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
