FTI 9.5in Ford AOD Street Racer Series Converters - Sprague Type - 3600 Hard Hit Stall

If you're building a Ford with an AOD transmission and looking to get serious about street performance, a high-stall torque converter is a key piece of the puzzle. This 9.5-inch Street Racer Series converter from FTI Performance is built to handle the demands of a performance-oriented vehicle, helping you launch harder and put that power to the ground more effectively. It's designed to work with applications aiming for a 3600 RPM stall speed, meaning the engine will rev to that point before the converter fully locks up and transfers power to the drivetrain under acceleration. This characteristic is crucial for getting a strong start off the line, especially with modified engines that make power higher in the RPM range.

FTI Performance builds these converters with a focus on durability and performance for street applications. The Sprague-type design is known for its reliability and efficient power transfer, especially when paired with the right engine and rear-end gearing. This particular converter is rated for a 3600 RPM stall, which is a popular choice for street/strip cars that see regular driving but also hit the drag strip. It's important to match your engine's power band and your vehicle's gearing to the converter's stall speed for optimal performance; too low a stall and you'll bog, too high and you might not get the most efficient transfer on the street. This converter is a well-built option for enthusiasts looking to improve their vehicle's launch characteristics without sacrificing too much street drivability.

Keep in mind that this converter is not CARB approved and cannot be shipped to California. It's also important to ensure your transmission is in good condition and properly set up to handle the increased stress from a higher stall converter. If you're unsure about compatibility with your specific build, it's always a good idea to consult with a performance transmission specialist or FTI Performance directly.
