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

If you're looking to get the most out of your 4L80E or 4L85E transmission, especially in a performance street application, a high-stall torque converter is key. This FTI Performance Street Racer Series converter is built for that purpose, featuring a 3600 RPM stall speed designed to let your engine rev up before the transmission engages, which is crucial for launching a powerful vehicle. It fits a wide range of trucks and SUVs, including models like the Chevrolet Silverado 2500 HD, Cadillac Escalade, and Bentley Arnage.

FTI builds these converters with a focus on durability and performance. The billet front cover and billet lockup piston are CNC-machined to resist premature clutch wear, meaning this converter can handle the abuse of hard launches and spirited driving. Inside, custom stator designs and multiple blade angle pumps are used to achieve the specific stall speeds like the 3600 RPM on this model. The fins are furnace-brazed and heli-welded for strength, and it includes 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 it works well with your engine's powerband. It's designed to be a direct replacement for your stock converter, simplifying the installation process. Remember that this part cannot be shipped to California due to emissions regulations.
