FTI 9.5in AODE/4R70/4R75 Billet Single Clutch Lock-Up Street Racer Series - 4000 Hard Hit Stall

If you're looking to get more out of your AODE, 4R70, or 4R75 transmission, especially for street racing or performance applications, a high-stall torque converter is a key component. This FTI Performance 9.5-inch Billet Lock-Up Street Racer Series converter is built to handle higher horsepower and deliver a harder hit off the line, aiming for a 4000 RPM stall speed. It's designed to work with a range of Ford and Mercury vehicles, including popular models like the Ford F-150, Crown Victoria, and Mercury Grand Marquis.

This converter features a solid billet cover for increased strength and durability, which is crucial when dealing with increased power. The internal components are furnace brazed and TIG welded, ensuring that the fins stay in place and the unit can withstand the stresses of aggressive driving. It also utilizes triple Torrington bearings, which help reduce friction and improve longevity compared to standard bearings. The lock-up feature means that at cruising speeds, the converter can mechanically couple the engine to the transmission, reducing slippage and improving fuel efficiency when you're not demanding maximum performance.

When installing a torque converter with a higher stall speed like this one, it's important to ensure your engine's power band aligns with the converter's stall rating. This helps you achieve the best performance off the line. This converter is a substantial upgrade for those looking to improve their vehicle's acceleration and overall performance feel. Always refer to the manufacturer's installation instructions for proper setup and fluid requirements.
