Description
ACC Performance designed this Boss Hog 3404HD Night Stalker Torque Converter for Towing with 1962-1973 GM Powerglide transmissions. This hand-built 12” converter has a stall speed 200-300 RPM over stock, and it has been leak and pressure tested as well as digitally balanced.
All Boss Hog torque converters are welded at the fins, not furnace-brazed, eliminating erosion over time. They include industrial-strength Torrington-type bearings that handle more torque than light-duty needle bearings. Aircraft aluminum washers instead of inferior fiber washers ensure all power transfers directly to the ground.
