FTI 9.5in 4L80E/4L85E Billet Triple Disc Lock-Up Street Racer Series - LS - 4000 Hard Hit Stall

This is the FTI Performance 9.5-inch Billet Triple Disc Lock-Up Street Racer Series torque converter, designed for LS engines paired with 4L80E and 4L85E transmissions. It's built to handle serious power and deliver a hard-hit stall speed around 4000 RPM, making it a solid choice for performance builds that demand quick acceleration and reliable power transfer. This converter is custom-built to match your specific engine and driving style, ensuring it works seamlessly with your setup.

FTI uses a computer-designed, CNC-machined billet front cover and a billet lockup piston, which significantly reduces clutch wear and increases durability. The internal components are also built tough, featuring furnace-brazed and heli-welded fins, a severe-duty sprague, and an anti-ballooning flanged impeller hub. These features combine to make the converter exceptionally strong and resistant to failure, even under demanding conditions. The custom stator designs and multiple blade angle pumps are key to achieving the specific stall speeds FTI offers, like the 4000 RPM stall on this particular model, which helps get your vehicle moving off the line quickly.

This torque converter is designed for a wide range of vehicles, including many Chevrolet and GMC trucks and SUVs, as well as some Bentley models. Because it's a custom-built unit, it's tailored to your specific needs, ensuring optimal performance for your LS-powered vehicle. It's important to note that this converter is not CARB approved and cannot be shipped to California.
