The 9in (245MM) Comp Torque Converter is engineered for high-performance automatic transmission builds where torque multiplication and converter lockup precision are critical to engine durability and overall drivetrain efficiency. This COAN converter is purpose-built for street performance, bracket racing, and heavy-duty towing applications where factory converters cannot withstand sustained load cycles or deliver the stall speed needed for optimized power delivery. Whether you're upgrading a small-block V8, LS engine swap, or reinforcing a truck's transmission package, a quality compensator-style converter becomes the foundation of reliable power transfer.
The 245mm diameter design balances mass and thermal capacity—critical factors in preventing converter overheat during load-bearing runs. A compensator-design torque converter regulates stall speed dynamically, allowing the engine to reach optimal RPM for maximum torque output before the transmission load fully engages, then tightening lockup progressively as throttle input stabilizes. This reduces transmission stress, improves fuel economy under cruise conditions, and extends fluid life by minimizing unnecessary heating. The COAN engineering standard ensures tight tolerances, quality welding, and validated performance across a wide range of engine displacements and transmission types, from 200 to 500+ horsepower builds.
This converter suits builders and mechanics working with TH350, TH400, 700R4, 4L60E, and comparable three- and four-speed automatic platforms in performance vehicles. Installation requires proper transmission alignment, pilot bushing clearance, and validation against your specific engine-transmission combination; consult manufacturer fitment charts or your transmission specialist to confirm compatibility with your application. At 26.6 lbs, the balanced weight distribution minimizes rotational inertia while maintaining structural rigidity—essential for consistent engagement feel and reduced parasitic loss during sustained driving.
