ACC 48441 GM 700R4 Night Stalker Torque Converter, 1600-2200 RPM, 12 in. Each

The Night Stalker Series is designed to handle as much as 500 horsepower. Comparable lines will only handle up to 300 horse power. ACC Performance puts the much larger Torrington type incased bearings throughout the converter where needed. These bearings will handle more raw power and abuse that the higher horsepower engines produce. Some of the competition uses 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 also weld up and four-corner tack-weld our turbine and impeller fins in order to maintain the highest strength and quality. ACC Performance has custom engineered our turbine hubs. Many competitors use a chromemoly steel hub that does not weld very well. If improperly welded, the hub could cause converter failure and or damage to your transmission. The stators are built with high flow vents and channels for greater cooling in order to handle the greater power and heat ranges. ACC Performance converters are 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 of the competitors use a dual bolt pattern converter to eliminate multiple part numbers, i.e./ th350 & 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. We at ACC are in the performance business and try to maximize horsepower at every level. ACC think you do too! NOTE: 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 and heavy vehicles and trucks.
