FTI Performance Street Racer Series 9.5in Billet Triple Disc 3600 Stall Torque Converter for LS 4L80E/4L85E (1991-2007)

Fits select 1991-2007 Chevrolet, GMC, Bentley, and AM General models equipped with LS-based engines and 4L80E/4L85E transmissions. The FTI Performance Street Racer Series (SRL) 9.5-inch billet triple disc lock-up torque converter is engineered for high-horsepower street and strip applications where heat management and durability are non-negotiable.

Built to solve the problem of premature clutch wear, this converter features a computer-designed, CNC-machined billet front cover and a matching billet lock-up piston. The internal assembly is reinforced for extreme duty with furnace-brazed and heli-welded fins, a severe-duty sprag, and an anti-ballooning flanged impeller hub to prevent internal distortion during high-RPM launches. This custom-configured unit provides the consistent 3600 RPM stall required for performance LS builds while maintaining the efficiency of a triple-disc lock-up system.
