The FTI Performance 9.5-inch Billet Street Racer torque converter for TH350/TH400 GM transmissions includes a 2800 rpm stall for a modest boost in initial response while maintaining daily drivability. Engineered and built in-house, the SR series uses TIG-welded, furnace-brazed fins, a heavy-duty race sprag and a hardened steel impeller; completed units are pressure-checked and computer-balanced for quality and dependability.
