FTI 9.5in NAG1/722.6 Multi-Plate Lock-Up Street Racer Series - 3600 Hard Hit Stall

The billet cover on this FTI Performance 9.5-inch torque converter is a solid starting point, showing this isn't just a stock replacement. It's built for the demands of a performance vehicle, specifically designed for the NAG1/722.6 transmission found in many Chrysler, Dodge, and Jeep models. This converter features a 3600 RPM stall speed, meaning the engine can rev up to 3600 RPM before the converter fully locks up and transfers power to the transmission. This characteristic is key for getting off the line quickly, especially if you've made other modifications to your engine or drivetrain.

Beyond the billet cover, FTI uses furnace brazing and TIG welding for all its internal components. This construction method ensures that the fins and fins are securely attached, which is crucial for reliability under higher horsepower and torque loads. The use of triple Torrington bearings also helps to reduce friction and improve durability, allowing the converter to handle the stress of repeated hard launches. This multi-plate lock-up design means it offers both strong performance when you need to accelerate and efficient power transfer once you're cruising.

When installing this torque converter, remember it's a significant drivetrain component. Ensure you have the correct transmission fluid and follow the manufacturer's recommended procedures for filling and priming the converter before installation. This converter is a popular choice for those looking to improve their vehicle's acceleration and overall performance feel, especially for street use with occasional track days.
