11in Break Away Torque Converter

The 11in Break Away Torque Converter (TCI 240900) is a precision-engineered fluid coupling designed for high-performance automatic transmission builds, particularly suited for TH350 and TH400 applications in drag racing, street performance, and specialized military vehicle platforms. This breakaway-style converter operates in the 2200–2600 RPM stall range, enabling controlled engagement and optimal power transfer during hard acceleration. Built for operators and technicians who demand reliable torque multiplication without the complexity of manual clutch management, this converter serves as a critical interface between engine and transmission in demanding high-load environments.

The breakaway design allows the converter to slip at initial launch, reducing shock loads on drivetrain components while the impeller and turbine reach synchronous speed—a critical feature in tactical and performance applications where durability under stress is non-negotiable. The 11-inch diameter and 2200–2600 RPM stall characteristics provide a balanced sweet spot between launch aggression and highway cruise efficiency, with internal vane geometry optimized for fluid dynamics across varying load conditions. Precision manufacturing and quality internal components ensure consistent performance across repeated duty cycles, essential for both civilian performance builds and specialized military applications where component failure is not an option.

This converter is engineered specifically for TH350 and TH400 transmission platforms, making it the go-to choice for restoration builds, high-output engine swaps, and specialized vehicle configurations requiring proven transmission coupling technology. Installation requires proper transmission alignment and fluid fill procedures; compatibility checks with your specific engine and transmission combination are essential before procurement. At 26.4 lbs and compact enough for standard transmission bell housing fitment, the 11in Break Away Torque Converter delivers reliable performance in both street and extreme-duty tactical vehicle platforms where transmission integrity directly impacts mission success.
