FTI 9.5in 4L80E/4L85E Billet Lock-Up Street Racer Series - LT - 3600 Stall

If you're looking to get the most out of your high-performance 4L80E or 4L85E transmission, especially in a street/strip application, a well-built torque converter is key. This FTI Performance Street Racer Series converter is designed to handle the demands of powerful engines and aggressive driving, offering a 3600 RPM stall speed for improved acceleration off the line. It's a popular choice for vehicles like the Chevrolet Silverado 2500 HD and Cadillac Escalade, where enhanced power transfer is a priority.

FTI builds these converters with serious performance in mind. The billet front cover and billet lockup piston are CNC-machined to ensure durability and prevent premature clutch wear, which can be a common issue with lesser converters under stress. Inside, you'll find custom stator designs and multiple blade angle pumps, all working together to achieve that specific stall speed. The fins are furnace-brazed and heli-welded for strength, and it features a severe-duty sprague and an anti-ballooning flanged impeller hub, making it a very solid option for demanding builds.

This converter is custom-built to match your specific needs and driving style, ensuring you get the performance you're looking for. While it's designed for a wide range of trucks and SUVs, including models like the Bentley Arnage and Chevrolet Suburban 2500, it's important to note that this specific converter is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guide for proper setup and fluid recommendations.
