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

If you're building a high-performance street machine or a dedicated race car that uses a 4L80E or 4L85E transmission, you need a torque converter that can handle the power and deliver consistent performance. This FTI Performance Street Racer Series torque converter is designed for just that. It features a 9.5-inch diameter and a 3600 RPM stall speed, making it a popular choice for LS-based engines looking for improved acceleration and responsiveness off the line.

FTI builds these converters with a computer-designed, CNC-machined billet front cover and a billet lockup piston. This construction means the clutch is built to last, avoiding premature wear that can plague lesser converters. Inside, you'll find custom stator designs and multiple blade angle pumps, all engineered to provide the stall speed and efficiency you need. The fins are furnace-brazed and heli-welded for extreme durability, and it includes a severe-duty sprague and an anti-ballooning flanged impeller hub, making this converter incredibly tough and reliable under demanding conditions.

This converter is custom-built to match your specific vehicle and driving style, ensuring it works seamlessly with your setup. It's designed to fit a wide range of vehicles, from classic trucks and SUVs like the Chevrolet Silverado 2500 HD and GMC Sierra 2500 to performance-oriented models like the Bentley Arnage. Remember, this converter is not CARB approved and cannot be shipped to California.
