FTI 9.5in TF-6/904 Street Racer Series Converters Sprague Type - 3600 Hard Hit Stall

If you're building a Mopar with a 904 or TF-6 transmission that sees regular street duty but also hits the drag strip, this FTI Performance 9.5-inch Street Racer Series torque converter is a solid option. It’s designed to handle more power than a stock converter and is built to last, even with frequent hard use. This converter is engineered to provide a 3600 RPM stall speed, meaning the engine will rev up to around 3600 RPM before the converter fully locks up and transfers power to the drivetrain under acceleration. This is ideal for performance applications where you want the engine to build boost or rev high before launching.

FTI builds these converters entirely in-house, focusing on strength and reliability. You'll find TIG-welded furnace-brazed fins for durability, a heavy-duty race sprag for positive engagement, and a hardened steel impeller. The billet front cover adds extra toughness, and the unit includes Triple Torrington bearings for smooth operation. Each converter is pressure-checked and computer-balanced to ensure it meets FTI's standards before it leaves their facility. This converter fits a wide range of Mopar vehicles from the mid-60s through the late 70s, including models like the Dodge Dart, Plymouth Barracuda, and Chrysler Imperial.

When you're looking for a torque converter that can keep up with your performance build, this FTI unit offers a well-built solution. It’s a non-lockup design, which is common for many street/strip applications where maximum torque multiplication at launch is key. Remember to consult FTI's specific recommendations for your transmission and engine combination to ensure optimal performance.
