ACC Performance Boss Hog 4945HD Night Stalker GM 4L60E/4L65E/4L70E Lock Up Torque Converter

ACC Performance designed this Boss Hog 4945HD Night Stalker Lock Up LS Torque Converter for Towing with GM 1998-Up 4L60E/4L65E/4L70E transmissions with a 2 step input shaft. This hand-built 12” converter has a stall speed 200-300 RPM over stock, and can also handle up to 500 horsepower!

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.
