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

FTI Performance is known for building robust drivetrain components designed for demanding applications. This 9.5-inch Billet Lock-Up Street Racer Series torque converter is a prime example, specifically crafted for LS engines paired with 4L80E and 4L85E transmissions. It’s engineered to handle significant power and deliver a strong stall speed, making it a solid choice for performance builds. This converter fits a wide range of vehicles, including models like the Chevrolet Silverado 2500 HD, Cadillac Escalade, and Bentley Arnage, offering a custom solution for many different applications.

What sets this converter apart is its construction. The front cover and lockup piston are CNC-machined from billet aluminum, which means they are incredibly strong and resist premature wear, unlike some stock components. FTI uses custom stator designs and multiple blade angle pumps to achieve specific stall speeds, like the 3800 RPM hard hit stall featured here, tailored to your engine's characteristics and how you drive. For added durability, the fins are furnace-brazed and heli-welded, and it features a severe-duty sprague and an anti-ballooning flanged impeller hub. This level of construction makes the converter exceptionally tough.

When you're looking for a torque converter that can withstand serious use and deliver consistent performance, this FTI unit is built to last. It’s designed to be a virtually indestructible upgrade for your drivetrain, ensuring you get the most out of your LS engine and transmission combination.
