8" MAXIMUM PERFORMANCE CONVERTER W/ CNC MACHINED BILLET ALUMINUM STATOR, "SUPER SPRAG"

The Coan Racing COA‑20550 8″ Maximum Performance Converter with CNC‑Machined Billet Aluminum Stator and Super Sprag is a compact yet formidable torque converter engineered for TH350 and TH400 transmissions in race-focused applications. At just 8 inches in diameter, it reduces rotating mass for lightning-quick throttle response while delivering aggressive stall characteristics tailored for drag, circle-track, or high-performance street use. The CNC-machined billet aluminum stator adds exceptional structural integrity and improved heat resistance over conventional designs, ensuring consistent hydraulic efficiency even under intense load.

Central to its strength is Coan’s proven “Super Sprag” one-way clutch assembly, which locks up firmly under hard acceleration to prevent slippage and ensure reliable torque holdoff at launch. Designed to perform under pressure, the COA‑20550 balances precision engineering, rugged construction, and sprint-ready performance in a tight, race-proven package. It's an optimal choice for enthusiasts seeking race-level torque management, consistent clutch engagement, and durable operation, all housed in a high-quality, compact converter architecture.
