The Coan Racing COA‑20430‑1S 9″ (245 mm) Maximum Performance Converter – Spragless, is a precision-engineered torque converter designed for high-power TH350 and TH400 transmissions. Featuring a compact 9-inch design with a billet steel stator and reinforced to resist ballooning, it maintains optimal pump clearances under extreme RPM and torque loads, crucial for maintaining hydraulic efficiency and long-term durability. By opting for a spragless configuration, this unit eliminates parasitic drag and delivers consistent, repeatable torque transfer, making it particularly well-suited for racing. 

Despite its compact size, the converter offers aggressive stall responsiveness thanks to Coan’s Maximum Performance build quality. Whether deployed on the strip or in high-intensity circuit applications, the COA‑20430‑1S delivers race-grade strength, efficient fluid dynamics, and repeatable performance in a lightweight, compact package.
