FTI 9.5in Ford AOD Street Racer Series Converters - Sprague Type - 3800 Hard Hit Stall - Non Lock-Up

FTI Performance is known for building serious drivetrain components for racers and high-performance street cars. This 9.5-inch Street Racer Series torque converter is a prime example, designed specifically for Ford AOD transmissions that demand serious power handling and a hard-hitting stall speed. If you're building a Ford AOD for drag racing or a high-performance street machine where a lock-up converter isn't needed, this unit is engineered to put your engine's power to the pavement effectively.

This converter features a Sprague-type sprag for robust engagement, crucial for handling the torque of modified engines. The 3800 RPM 'hard hit' stall rating means the engine will rev up significantly before the converter fully couples, allowing your engine to build boost or reach its powerband before launching. This is ideal for applications where you want a dramatic launch and don't need the efficiency of a lock-up clutch for cruising. The non-lock-up design simplifies installation and is often preferred in dedicated drag racing setups where fuel economy at cruising speeds is not a concern.

When installing a non-lock-up converter like this one, remember that it will not provide a direct mechanical link between the engine and transmission at lower RPMs, which can lead to higher transmission temperatures during extended slow-speed driving. Ensure your transmission cooling system is up to the task, possibly with an auxiliary cooler. This converter is a solid choice for those looking to maximize acceleration from a standstill with their Ford AOD transmission.
