Product Details

The Hays Twister 3/4 Race Torque Converter is a high-performance, hand-built torque converter engineered for Ford C4 transmissions in racing and high-horsepower street applications. This case-filled converter is built, tested, and proven to support up to 650 HP, making it an ideal choice for serious performance enthusiasts.

Key Features:

  • Heavy-Duty Construction: Utilizes heavy-duty Torrington bearings for exceptional strength and durability under extreme loads
  • 650 HP Rated: Built and tested to reliably handle up to 650 horsepower in demanding applications
  • Superior Welding Process: Internally welded construction (not brazed) provides longer converter life and enhanced consistency compared to brazed units
  • High-Flow Stator Design: Features stators with high-flow vents and channels to promote cooling in heat-producing, high-horsepower applications
  • Weight-Optimized Design: Single-application design reduces weight compared to multi-bolt pattern converters for improved acceleration and horsepower transfer
  • Advanced Manufacturing: State-of-the-art spray welding process used in critical areas provides clean, strong, consistent fusion while increasing strength through work hardening
  • Quality Assurance: Each converter is hand-built and inspected at every step of assembly to ensure top-of-the-line quality
  • Expert Support: Industry-leading tech support team available to assist with stall speed selection for your specific application

The Hays Twister 3/4 Race series is available in multiple stall speeds to match your vehicle's engine characteristics and intended use. The case-filled design provides additional strength and heat dissipation for consistent performance lap after lap.
