The Coan Racing COA‑20360‑2X “Super Mega XL” 258 mm Xtra‑Lite Billet Series Aluminum Converter is a premium, race-focused torque converter engineered for TH350 and TH400 transmissions. Crafted from lightweight CNC-machined billet aluminum, the bolt-together housing and six-bolt billet cover provide exceptional rigidity while allowing quick access for maintenance or tuning. This 258 mm unit combines compact size with strength, delivering reduced rotating mass for faster throttle response without compromising durability.

The Super Mega XL is offered in a spragless configuration to minimize internal drag, though it can be upgraded with an optional XST sprag assembly to further enhance torque-holding capability. Ideal for extreme-racing applications like Pro‑Mod, turbocharged builds, and heavy-duty drag setups, this converter balances efficiency and rugged performance in a lightweight, serviceable design.
