Street Applications Up To 500-HP
The Nightstalker Series Torque Converter is designed to handle as much as 500 horsepower. The Night Stalker series converters are OEM factory sized in order to maintain a lower level of operating temperatures and for the best torque multiplication. These converters are ideal for just over stock applications, heavy vehicles and trucks. At ACC Performance Products, the only thing they do is Boss Hog Torque Converters. And they are really good at building Torque Converters. ACC proudly manufactures all Boss Hog torque converters, by hand, in the USA. They rigorously follow Six Sigma world class manufacturing methods and ISO 9000 quality standards. Boss Hog torque converters are available for your street, street/strip, drag race, or off-road racer.

During the hand-built construction process, ACC Performance use a much larger industrial Torrington-type incased bearings, that give these converters the ability to handle thousands of pounds of torque, throughout the converter where needed. These bearings will handle more raw power and abuse that the higher horsepower engines produce. Some other companies use a smaller needle type bearing. Needle bearings are not incased, which makes them susceptible to picking up trash or debris from the transmission fluid, which can lead up to heat build up and failure. ACC Performance has custom engineered their own turbine hubs and weld up and "four-corner" tack weld their turbine and impeller fins in order to maintain the highest quality, strength, and durability. Many competitors use a chrome-moly steel hub that does not weld very well. If improperly welded, the hub could cause converter failure and or damage to your transmission. ACC's stators are built with high flow vents and channels for greater cooling in order to handle the greater power and heat ranges.
These converters are also engineered with a single bolt pattern for the rotating mass. This makes ACC Performance Torque Converters surprisingly light, keeping the weight of the converter off of the rotating mass of the motor. This will free up your motor and allow it to rev-up through the RPM range quicker, helping your engine put more power to the ground. Some competitors use a dual bolt pattern converter to eliminate multiple part numbers (i.e./ TH-350 & TH-400's). These transmissions using the same converter with a dual bolt pattern, will add 3 to 4 pounds of weight to the converter. This adds weight to the rotating mass of the engine, costing you nothing but horsepower & torque. All ACC Converters are designed, engineered, hand assembled and tested in the USA to ensure that you are getting the best converter money can buy!
