The FTI Performance 9.5-inch Billet Street Racer torque converter for TH350/TH400 GM transmissions delivers a 3800 rpm stall for stronger launches and improved on-throttle response when pushing the car on the street or strip. SR series units are engineered with TIG-welded, furnace-brazed fins, a heavy-duty race sprag and a hardened steel impeller, then pressure-checked and computer-balanced to ensure reliable, trouble-free operation.
