ACC Performance Boss Hog 49480 Night Stalker GM 4L80E/4L85E LS Lock Up Torque Converter

ACC Performance designed this Boss Hog 49480 Night Stalker Lock Up LS Torque Converter for GM 4L80E and 4L85E transmissions with the 2 step input shaft and 2 inch impeller hub. This hand-built 13” converter has a stock stall speed, 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.
