GM Torque Converter 10in Big Shot 4100-4500 RPM

The GM Torque Converter 10in Big Shot 4100-4500 RPM from Transmission Specialties is a precision-engineered torque converter designed for GM TH350 and TH400 transmissions. This 10-inch diameter unit delivers a 4100–4500 RPM stall speed, optimizing launch characteristics and driveline responsiveness in high-performance and heavy-duty applications.

Built to exacting specifications, this torque converter represents the engineering standard for operators and enthusiasts who demand repeatable, reliable torque multiplication across demanding driving conditions. The stall window is engineered to allow the engine to build torque and RPM before load transfer occurs, translating to controlled acceleration and improved off-the-line performance without excessive slip or heat generation.

Operators of high-output diesel trucks, performance muscle cars, and specialized recovery vehicles depend on torque converters that bridge engine and transmission without slipping or cavitation under sustained load. The Big Shot series is purpose-built for crews running extended duty cycles—towing, rock crawling, and other demanding applications.
