FTI 9.5in Ford C4 Street Racer Series Converters - 26 Spline - 10.5in BC 4000 Hard Hit Stall

What you get with this FTI Performance Street Racer Series torque converter is a 9.5-inch unit designed for Ford C4 transmissions, featuring a 26-spline input and a 10.5-inch bolt circle. This converter is built for a 4000 RPM stall speed, meaning it's set up to let your engine rev up to about 4000 RPM before the converter fully locks up and transfers power to the drivetrain under hard acceleration. It's a well-built piece aimed at street/strip applications where you want a noticeable performance improvement off the line.

The Street Racer Series is FTI's popular line for vehicles that see regular street use but are also taken to the drag strip. They use a specific internal design and a custom-tuned stall speed to give you that strong launch you're looking for without being so loose that it makes the car difficult to drive in traffic. The 26-spline count is important for matching up with the correct transmission input shaft. FTI is known for their attention to detail in balancing and building these units, which helps ensure smooth operation and durability for the intended use.

Keep in mind that this converter is not CARB approved, so it cannot be shipped to California. If you're building a Ford C4 for performance driving and want a converter that offers a significant improvement in launch characteristics for a 4000 RPM stall, this FTI unit is a solid option. Make sure to check your transmission's input shaft spline count to confirm compatibility.
