The FTI Performance 9.5-inch Street Racer torque converter for Ford C6 applications uses a Sprague-type 1.375-inch pilot and is tuned to a 3800 hard-hit stall. As a Street Racer Series unit, the 9.5-inch triple-disc lock-up design fits C6 transmissions that accept a 1.375-inch Sprague pilot and provides a higher-stall option for more aggressive launch behavior.
