ACC Performance 49451 Night Stalker Torque Converter 1600-2200 Stall 4L60E/4L65E

Boss Hog Night Stalker Series Converters are engineered and precision assembled by hand in the USA to to 500 hp.

ACC Performance uses larger Torrington bearings where needed. Torrington bearings handle more power than smaller needle type bearings others use. Needle bearings are not incased, which makes them susceptible to picking up trash in transmission fluid, in turn leading to heat build up and failure.

ACC Performance also welds-up and four corner tack-welds turbine and impeller fins to maintain the highest strength. This will stop fin degradation or deformity. They also have custom engineered turbine hubs to maintain the highest quality, strength, and durability. Some of the competitors use a chromemoly steel turbine hub that does not weld very well. If improperly welded, it can cause converter failure and or damage to your transmission.

Stators are built with high flow vents and channels for greater cooling in order to handle the much greater power and heat ranges.

Rather than using a dual bolt pattern to fit multiple applications, ACC Performance converters are engineered with a single bolt pattern for less rotating mass. This makes them surprisingly light, keeping the weight of the converter off of the rotating mass of the motor. That allows your engine to rev-up through the RPM range quicker, helping put more power to the ground.

NOTE: The Night Stalker series converters are 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. For NOS applications see the Outlaw Series.;

• Boss Hog Street Bandit Series Converters handle up to 500 hp
• Torrington bearings where needed to handle more power than smaller needle type bearings others use
• Welded turbine and impeller fins for added accuracy, strength and durabiility. Welded fins harden, which maintains stall under extreme duty conditions.
• Custom engineered turbine hubs to maintain the highest quality, strength, and durability
• Stators are built with high flow vents and channels for greater cooling in order to handle the much greater power and heat ranges
• Converters are single bolt pattern for less rotating mass when applicable. Dual bolt pattern converters that fit multiple applications weigh more robbing horsepower.
• Engineered and precision assembled by hand in the United States
• Factory sized to reduce temperatures. Ideal for mildly modified applications, heavy vehicles, and trucks.
