FTI 9.5in Ford C4 Street Racer Series Converters Sprague Type - 26 Spline - 10.5in BC 2800 Stall

If you're building a Ford C4 transmission for a street/strip application, a good torque converter is key to getting that power to the ground effectively. This FTI Performance Street Racer Series converter is built for those who want improved performance without sacrificing too much drivability. It's designed to work with C4 transmissions and features a 26-spline input, a 10.5-inch bolt circle, and a 2800 RPM stall speed, making it a solid choice for a wide range of street performance builds.

FTI Performance puts a lot of attention into how these converters are put together. They use a Sprague type lock-up mechanism, which helps reduce heat and improve efficiency when you're cruising. This means you get a more comfortable ride and better fuel economy on the highway compared to non-lock-up converters. The 2800 stall speed is a sweet spot for many performance street cars, allowing for a strong launch off the line when you hit the throttle, while still being manageable in traffic. The 26-spline count ensures it mates correctly with the C4 transmission's input shaft.

When you're looking at a converter like this, it's important to consider your engine's powerband and rear-end gearing. A 2800 stall speed is generally a good match for engines making power in the 3000-6000 RPM range. This converter is not CARB approved and cannot be shipped to California. For optimal performance and longevity, always follow the manufacturer's installation guidelines, which typically include proper filling of the converter with transmission fluid before installation and ensuring correct cooler line flow.
