FTI 9.5in 4L80E/4L85E Billet Lock-Up Street Racer Series - LT - 3800 Hard Hit Stall

If you're looking to get the most out of your 4L80E or 4L85E transmission, this FTI Performance Street Racer Series torque converter is a serious upgrade. It's designed to handle a lot of power and deliver a strong hit off the line, with a stall speed around 3800 RPM. This converter fits a wide range of vehicles, including many GM trucks and SUVs like the Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD, as well as luxury vehicles like the Bentley Arnage.

FTI builds these converters with a computer-designed, CNC-machined billet front cover and a billet lockup piston. This means the clutch is much less likely to wear out prematurely, even under demanding conditions. They also use custom stator designs and multiple blade angle pumps to achieve specific stall speeds, and this particular model is set up for a hard hit around 3800 RPM. The fins are furnace-brazed and heli-welded for strength, and it features a severe-duty sprague and an anti-ballooning flanged impeller hub. Basically, FTI builds these to be tough and reliable, even when you're pushing your vehicle hard.

Because these are custom-built to your specific needs and driving style, it's important to provide as much detail as possible when ordering. This ensures you get a converter that perfectly matches your setup, whether you're building a street machine or a dedicated race vehicle. Remember, this converter is not CARB approved and cannot be shipped to California.
