What is a torque converter stall speed and why does it matter?

Stall speed is the RPM at which the torque converter will lock up and transfer power directly from the engine to the transmission. A higher stall speed, like the 4000 RPM on this converter, allows the engine to rev higher before engaging, which is beneficial for launching a performance vehicle quickly.

What does 'billet' mean in the context of a torque converter?

Billet refers to a solid block of metal that has been machined to create the part, in this case, the front cover and lockup piston. This manufacturing process results in a much stronger and more precise component compared to cast or stamped parts, making it ideal for high-performance applications.

What transmissions does this torque converter fit?

This FTI Performance torque converter is specifically designed for 700R4 and early 4L60 transmissions that use a 27-spline input shaft. It's important to verify your transmission model and spline count before purchasing.
