Description
Performance Torque Converter. The Hays Twister Full Race Torque Converter; 11-1/2-Inch Bolt Pattern; 2800-3200 RPM Stall is engineered to deliver superior power transmission for racing and high-performance applications. It is designed to handle extreme conditions involving trans-brakes and power adders like nitrous, superchargers, and turbochargers, improving overall acceleration and power delivery.
Construction and Appearance. This race-grade torque converter is hand-built with meticulous attention to detail, employing state-of-the-art spray welding techniques for exceptional strength and durability. Internal components, including heavy-duty Torrington bearings and high-flow vented stators, are internally welded and assembled for maximum longevity and consistent performance under high stress.
Installation. Installation is straightforward for professionals familiar with TH400 transmissions. This converter features a bolt pattern and dimensions that fit many TH400 applications without requiring drilling or modifications; however, proper fit depends on specific transmission, flexplate bolt pattern, crank pilot, and vehicle combination.
