Yank SS Series Torque Converters — 9.50-Inch Billet Street/Strip Power

Build a street car that hits like a bracket racer with Yank Performance Converters Street/Strip (SS) Series—purpose-built for setups that see real dragstrip time. These 9.5-inch billet converters use a solid billet lockup clutch and premium internals—one-piece roller-burnished hub, new Torrington bearings, fully furnace-brazed pump/impeller, and hardened splines—for crisp launches and efficient lockup up to 650 RWHP. Stall choices from 2,800 to 4,000 rpm let you match your cam and gearing, with fitments for popular GM automatics, including 4L60/65/70E, 4L80/85E, and 6L80/6L90.
