FTI 9.5in 4L80E/4L85E Billet Triple Disc Lock-Up Street Racer Series - LS - 3200 Stall

When you're looking to get the most out of your LS-powered vehicle with a 4L80E or 4L85E transmission, this FTI Performance Street Racer Series torque converter is a solid choice. You'll receive the torque converter itself, featuring a billet front cover and a billet lockup piston, designed to handle the demands of higher horsepower applications. This converter is built for a 3200 RPM stall speed, which means it's engineered to let your engine rev up to around 3200 RPM before the converter fully locks up and transfers power efficiently. This is ideal for street performance where you want a good balance between off-the-line acceleration and drivability.

FTI builds these converters with serious attention to durability. The billet construction for the front cover and lockup piston helps prevent premature wear, a common issue with lesser converters under stress. Inside, you'll find furnace-brazed and heli-welded fins for strength, a severe-duty sprague mechanism, and an anti-ballooning flanged impeller hub. These features combine to make the converter exceptionally robust, capable of handling significant power. The custom stator and multiple blade angle pump designs are tailored to achieve specific stall speeds, like the 3200 RPM rating on this model, ensuring it matches your engine's power band and your driving style for improved performance.

This torque converter is designed to fit a wide range of vehicles, including many GM trucks and SUVs from the 90s and early 2000s, as well as some Bentley models. It's a direct replacement for your stock torque converter, but with significantly enhanced performance and durability. Because this is a performance part, it's always a good idea to consult with your transmission builder or a performance specialist to ensure it aligns with your specific build and goals.
