FTI 9.5in Ford C6 Street Racer Series Converters - Sprague Type 1.848in Pilot - 4000 Hard Hit Stall

The 1.848-inch pilot diameter on this FTI Performance Street Racer Series torque converter is a key detail for ensuring a solid connection with your Ford C6 transmission's input shaft. This converter is built for performance applications, specifically designed to handle a 4000 RPM stall speed, meaning it's intended for engines that make power higher up in the rev range and need the converter to hold that engine speed before engaging the transmission. It's a well-built unit aimed at street/strip vehicles where a hard hit off the line is desired.

FTI Performance constructs these Street Racer converters with a focus on durability and performance. The internal components are selected to withstand the demands of higher horsepower engines and aggressive driving. The 9.5-inch diameter is a common size for performance applications, offering a good balance between efficiency and stall speed. This converter is a popular choice for enthusiasts looking to improve their vehicle's acceleration from a standstill, especially when paired with a performance camshaft and other engine modifications that shift the power band higher.

When installing this torque converter, remember that it's crucial to ensure proper engagement with the transmission's pump. You should feel and hear a distinct 'clunk' as it seats fully. It's also important to fill the converter with a quart or two of transmission fluid before installation to help prime the system. Keep in mind that this converter is not CARB approved and cannot be shipped to California due to emissions regulations.
